OUR NOTICE AND TERMS AND CONDITIONS OF THE GNU GENERAL PUBLIC LICENSE
|
||||
|
||||
Our Preamble Notice
|
||||
|
||||
A. This notice is required to be provided under our contract with the U.S.
|
||||
Department of Energy (DOE). This work was produced at the University of
|
||||
California, Lawrence Livermore National Laboratory under Contract No.
|
||||
W-7405-ENG-48 with the DOE.
|
||||
|
||||
B. Neither the United States Government nor the University of California nor
|
||||
any of their employees, makes any warranty, express or implied, or assumes any
|
||||
liability or responsibility for the accuracy, completeness, or usefulness of
|
||||
any information, apparatus, product, or process disclosed, or represents that
|
||||
its use would not infringe privately-owned rights.
|
||||
|
||||
C. Also, reference herein to any specific commercial products, process, or
|
||||
services by trade name, trademark, manufacturer or otherwise does not
|
||||
necessarily constitute or imply its endorsement, recommendation, or favoring
|
||||
by the United States Government or the University of California. The views and
|
||||
opinions of authors expressed herein do not necessarily state or reflect those
|
||||
of the United States Government or the University of California, and shall not
|
||||
be used for advertising or product endorsement purposes.
|
||||
|
||||
The precise terms and conditions for copying, distribution and modification
|
||||
follows.
|
||||
|
||||
GNU Terms and Conditions for Copying, Distribution, and Modification
|
||||
|
||||
0. This License applies to any program or other work which contains a notice
|
||||
placed by the copyright holder saying it may be distributed under the terms of
|
||||
this General Public License. The "Program," below, refers to any such program
|
||||
or work, and a "work based on the Program" means either the Program or any
|
||||
derivative work under copyright law: that is to say, a work containing the
|
||||
Program or a portion of it, either verbatim or with modifications and/or
|
||||
translated into another language. (Hereinafter, translation is included
|
||||
without limitation in the term "modification".) Each licensee is addressed as
|
||||
"you."
|
||||
|
||||
Activities other than copying, distribution and modification are not covered by
|
||||
this License; they are outside its scope. The act of running the Program is
|
||||
not restricted, and the output from the Program is covered only if its contents
|
||||
constitute a work based on the Program (independent of having been made by
|
||||
running the Program). Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's source code as
|
||||
you receive it, in any medium, provided that you conspicuously and
|
||||
appropriately publish on each copy an appropriate copyright notice and
|
||||
disclaimer of warranty; keep intact all the notices that refer to this License
|
||||
and to the absence of any warranty; and give any other recipients of the
|
||||
Program a copy of this License along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and you may
|
||||
at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion of it,
|
||||
thus forming a work based on the Program, and copy and distribute such
|
||||
modifications or work under the terms of Section 1 above, provided that you
|
||||
also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices stating
|
||||
that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in whole
|
||||
or in part contains or is derived from the Program or any part thereof,
|
||||
to be licensed as a whole at no charge to all third parties under the terms
|
||||
of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively when run,
|
||||
you must cause it, when started running for such interactive use in the
|
||||
most ordinary way, to print or display an announcement including an
|
||||
appropriate copyright notice and a notice that there is no warranty (or
|
||||
else, saying that you provide a warranty) and that users may redistribute
|
||||
the program under these conditions, and telling the user how to view a copy
|
||||
of this License. (Exception: if the Program itself is interactive but does
|
||||
not normally print such an announcement, your work based on the Program is
|
||||
not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If identifiable
|
||||
sections of that work are not derived from the Program, and can be reasonably
|
||||
considered independent and separate works in themselves, then this License, and
|
||||
its terms, do not apply to those sections when you distribute them as separate
|
||||
work. But when you distribute the same section as part of a whole which is a
|
||||
work based on the Program, the distribution of the whole must be on the terms
|
||||
of this License, whose permissions for other licensees extend to the entire
|
||||
whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest your
|
||||
rights to work written entirely by you; rather, the intent is to exercise the
|
||||
right to control the distribution of derivative or collective works based on
|
||||
the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program with the
|
||||
Program (or with a work based on the Program) on a volume of a storage or
|
||||
distribution medium does not bring the other work under the scope of this
|
||||
License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it, under
|
||||
Section 2) in object code or executable form under the terms of Sections 1 and
|
||||
2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable source
|
||||
code, which must be distributed under the terms of Sections 1 and 2 above
|
||||
on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three years, to
|
||||
give any third party, for a charge no more than your cost of physically
|
||||
performing source distribution, a complete machine-readable copy of the
|
||||
corresponding source code, to be distributed under the terms of Sections 1
|
||||
and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer to
|
||||
distribute corresponding source code. (This alternative is allowed only
|
||||
for noncommercial distribution and only if you received the program in
|
||||
object code or executable form with such an offer, in accord with
|
||||
Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form the work for making
|
||||
modifications to it. For an executable work, complete source code means all
|
||||
the source code for all modules it contains, plus any associated interface
|
||||
definition files, plus the scripts used to control compilation and installation
|
||||
of the executable. However, as a special exception, the source code
|
||||
distributed need not include anything that is normally distributed (in either
|
||||
source or binary form) with the major components (compiler, kernel, and so on)
|
||||
of the operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering access to copy
|
||||
from a designated place, then offering equivalent access to copy the source
|
||||
code from the same place counts as distribution of the source code, even though
|
||||
third parties are not compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program except as
|
||||
expressly provided under this License. Any attempt otherwise to copy, modify,
|
||||
sublicense or distribute the Program is void, and will automatically terminate
|
||||
your rights under this License. However, parties who have received copies, or
|
||||
rights, from you under this License will not have their licenses terminated so
|
||||
long as such parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not signed it.
|
||||
However, nothing else grants you permission to modify or distribute the Program
|
||||
or its derivative works. These actions are prohibited by law if you do not
|
||||
accept this License. Therefore, by modifying or distributing the Program (or
|
||||
any work based on the Program), you indicate your acceptance of this License to
|
||||
do so, and all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the Program),
|
||||
the recipient automatically receives a license from the original licensor to
|
||||
copy, distribute or modify the Program subject to these terms and conditions.
|
||||
You may not impose any further restrictions on the recipients' exercise of the
|
||||
rights granted herein. You are not responsible for enforcing compliance by
|
||||
third parties to this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues), conditions
|
||||
are imposed on you (whether by court order, agreement or otherwise) that
|
||||
contradict the conditions of this License, they do not excuse you from the
|
||||
conditions of this License. If you cannot distribute so as to satisfy
|
||||
simultaneously your obligations under this License and any other pertinent
|
||||
obligations, then as a consequence you may not distribute the Program at all.
|
||||
For example, if a patent license would not permit royalty-free redistribution
|
||||
of the Program by all those who receive copies directly or indirectly through
|
||||
you, then the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under any
|
||||
particular circumstance, the balance of the section is intended to apply and
|
||||
the section as a whole is intended to apply in other circumstances.
|
||||
|
||||
It is not the purpose to this section to induce you to infringe any patents or
|
||||
other property right claims or to contest validity of any such claims; this
|
||||
section has the sole purpose of protecting the integrity of the free software
|
||||
distribution system, which is implemented by public license practices. Many
|
||||
people have made generous contributions to the wide range of software
|
||||
distributed through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing to
|
||||
distribute software through any other system and a licensee cannot impose that
|
||||
choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to be a
|
||||
consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in certain
|
||||
countries either by patents or by copyrighted interfaces, the original
|
||||
copyright holder who places the Program under this License may add an explicit
|
||||
geographical distribution limitation excluding those countries, so that
|
||||
distribution is permitted only in or among countries not thus excluded. In
|
||||
such case, this License incorporates the limitation as if written in the body
|
||||
of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions of the
|
||||
General Public License from time to time. Such new versions will be similar in
|
||||
spirit to the present version, but may differ in detail to address new problems
|
||||
or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any later
|
||||
version," you have the option of following the terms and conditions either of
|
||||
that version of any later version published by the Free Software Foundation.
|
||||
If the Program does not specify a version number of this License, you may
|
||||
choose any version ever published by the Free Software Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free programs
|
||||
whose distribution conditions are different, write to the author to ask for
|
||||
permission. For software which is copyrighted by the Free Software Foundation,
|
||||
write to the Free Software Foundation; we sometimes make exceptions for this.
|
||||
Our decision to grant permission will be guided by the two goals of preserving
|
||||
the free status of all derivatives of our free software and or promoting the
|
||||
sharing and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
|
||||
THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
|
||||
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE
|
||||
PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
|
||||
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
|
||||
FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
|
||||
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
|
||||
YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
|
||||
ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE
|
||||
PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
||||
GENERAL, SPECIAL INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
|
||||
INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
|
||||
BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
|
||||
FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER
|
||||
OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS

Changes in IOR-2.10.3
|
||||
* bug 2962326 "Segmentation Fault When Summarizing Results" fixed
|
||||
* bug 2786285 "-Wrong number of parameters to function H5Dcreate" fixed
|
||||
(NOTE: to compile for HDF5 1.6 libs use "-D H5_USE_16_API")
|
||||
* bug 1992514 "delay (-d) doesn't work" fixed
|
||||
Contributed by demyn@users.sourceforge.net
|
||||
* Ported to Windows. Required changes related to 'long' types, which on Windows
|
||||
are always 32-bits, even on 64-bit systems. Missing system headers and
|
||||
functions acount for most of the remaining changes.
|
||||
New files for Windows:
|
||||
- IOR/ior.vcproj - Visual C project file
|
||||
- IOR/src/C/win/getopt.{h,c} - GNU getopt() support
|
||||
See updates in the USER_GUIDE for build instructions on Windows.
|
||||
* Fixed bug in incrementing transferCount
|
||||
* Fixed bugs in SummarizeResults with mismatched format specifiers
|
||||
* Fixed inconsistencies between option names, -h output, and the USER_GUIDE.

||||
|
||||
Changes in IOR-2.10.2:
|
||||
Hodson, 8/18/2008:
|
||||
|
||||
The modifications to IOR-2.10.1 extend existing random I/O capabilities and
|
||||
enhance performance output statistics.
|
||||
|
||||
cli script Description
|
||||
----- ----------------- ----------------------------------------
|
||||
1) -A N testnum - test reference number for easier test
|
||||
identification in log files
|
||||
2) -Q N taskpernodeoffset - for read tests. Use with -C & -Z options
|
||||
If -C (reordertasks) specified,
|
||||
then node offset read by CONSTANT N.
|
||||
If -Z (reordertasksrandom) specified,
|
||||
then node offset read by RANDOM >= N.
|
||||
3) -Z reordertasksrandom - random node task ordering for read tests
|
||||
In this case, processes read
|
||||
data written by other processes with
|
||||
node offsets specified by the -Q option
|
||||
and -X option.
|
||||
4) -X N reordertasksrandomseed - random seed for -Z (reordertasksrandom)
|
||||
If N>=0, use same seed for all iters
|
||||
If N< 0, use different seed for ea. iter
|
||||
5) -Y fsyncperwrite - perform fsync after every POSIX write
|
||||
|
||||
Fixes in IOR-2.10.1:
|
||||
* added '-J' setAlignment option for HDF5 alignment in bytes; default value
|
||||
is 1, which does not set alignment
|
||||
* changed how HDF5 and PnetCDF calculate performance -- formerly each used
|
||||
the size of the stat()'ed file; changed it to be number of data bytes
|
||||
transferred. these library-generated files can have large headers and
|
||||
filler as well as sparse file content
|
||||
* found potential overflow error in cast -- using IOR_offset_t, not int now
|
||||
* replaced HAVE_HDF5_NO_FILL macro to instead directly check if H5_VERS_MAJOR
|
||||
H5_VERS_MINOR are defined; if so, then must be HDF5-1.6.x or higher for
|
||||
no-fill usage.
|
||||
* corrected IOR_GetFileSize() function to point to HDF5 and NCMPI versions of
|
||||
IOR_GetFileSize() calls
|
||||
* changed the netcdf dataset from 1D array to 4D array, where the 4 dimensions
|
||||
are: [segmentCount][numTasksWorld][numTransfers][transferSize]
|
||||
This patch from Wei-keng Liao allows for file sizes > 4GB (provided no
|
||||
single dimension is > 4GB).
|
||||
* finalized random-capability release
|
||||
* changed statvfs() to be for __sun (SunOS) only
|
||||
* retired Python GUI
|
||||
|
||||
Fixes in IOR-2.10.0.1:
|
||||
* Cleaned up WriteOrRead(), reducing much to smaller functions.
|
||||
* Added random capability for transfer offset.
|
||||
* modified strtok(NULL, " \t\r\n") in ExtractHints() so no trailing characters
|
||||
* added capability to set hints in NCMPI
|
||||
|
||||
Fixes in IOR-2.9.6.1:
|
||||
* for 'pvfs2:' filename prefix, now skips DisplayFreeSpace(); formerly this
|
||||
caused a problem with statvfs()
|
||||
* changed gethostname() to MPI_Get_processor_name() so for certain cases
|
||||
when gethostname() would only return the frontend node name
|
||||
* added SunOS compiler settings for makefile
|
||||
* updated O_DIRECT usage for SunOS compliance
|
||||
* changed statfs() to instead use statvfs() for SunOS compliance
|
||||
* renamed compiler directive _USE_LUSTRE to _MANUALLY_SET_LUSTRE_STRIPING
|
||||
|
||||
Fixes in IOR-2.9.5:
|
||||
* Wall clock deviation time relabeled to be "Start time skew across all tasks".
|
||||
* Added notification for "Using reorderTasks '-C' (expecting block, not cyclic,
|
||||
task assignment)"
|
||||
* Corrected bug with read performance with stonewalling (was using full size,
|
||||
stat'ed file instead of bytes transfered).
|
||||
|
||||
Fixes in IOR-2.9.4:
|
||||
* Now using IOR_offset_t instead of int for tmpOffset in IOR.c:WriteOrRead().
|
||||
Formerly, this would cause error in file(s) > 2GB for ReadCheck. The
|
||||
more-commonly-used WriteCheck option was not affected by this.
|
||||
|
||||
Fixes in IOR-2.9.3:
|
||||
* Changed FILE_DELIMITER from ':' to '@'.
|
||||
* Any time skew between nodes is automatically adjusted so that all nodes
|
||||
are calibrated to the root node's time.
|
||||
* Wall clock deviation time is still reported, but have removed the warning
|
||||
message that was generated for this. (Didn't add much new information,
|
||||
just annoyed folks.)
|
||||
* The '-j' outlierThreshold option now is set to 0 (off) as default. To use
|
||||
this, set to a positive integer N, and any task who's time (for open,
|
||||
access, etc.) is not within N seconds of the mean of all the tasks will show
|
||||
up as an outlier.
|
||||
|
||||
Fixes in IOR-2.9.2:
|
||||
* Simple cleanup of error messages, format, etc.
|
||||
* Changed error reporting so that with VERBOSITY=2 (-vv) any error encountered
|
||||
is displayed. Previously, this was with VERBOSITY=3, along with full test
|
||||
parameters, environment, and all access times of operations.
|
||||
* Added deadlineForStonewalling option (-D). This option is used for measuring
|
||||
the amount of data moved in a fixed time. After the barrier, each task
|
||||
starts its own timer, begins moving data, and the stops moving data at a
|
||||
prearranged time. Instead of measuring the amount of time to move a fixed
|
||||
amount of data, this option measures the amount of data moved in a fixed
|
||||
amount of time. The objective is to prevent tasks slow to complete from
|
||||
skewing the performance.
|
||||
|
||||
Fixes in IOR-2.9.1:
|
||||
* Updated test script to run through file1:file2 cases.
|
||||
* Program exit code is now total numbers of errors (both writecheck and
|
||||
readcheck for all iterations), unless quitOnError (-q) is set.
|
||||
* For various failure situations, replace abort with warning, including:
|
||||
- failed uname() for platform name now gives warning
|
||||
- failed unlink() of data file now gives warning
|
||||
- failed fsync() of data file now gives warning
|
||||
- failed open() of nonexistent script file now gives warning
|
||||
* Changed labelling for error checking output to be (hopefully) more
|
||||
clear in details on errors for diagnostics.
|
||||
* Another fix for -o file1:file2 option.
|
||||
* Corrected bug in GetTestFileName() -- now possible to handle -o file1:file2
|
||||
cases for file-per-proc.
|
||||
|
||||
Fixes in IOR-2.9.0:
|
||||
* Improved checkRead option to reread data from different node (to avoid
|
||||
cache) and then compare both reads.
|
||||
* Added outlierThreshold (-j) option to give warning if any task is more than
|
||||
this number of seconds from the mean of all participating tasks. If so, the
|
||||
task is identified, its time (start, elapsed create, elapsed transfer,
|
||||
elapsed close, or end) is reported, as is the mean and standard deviation for
|
||||
all tasks. The default for this is 5, i.e. any task not within 5 seconds of
|
||||
the mean for those times is displayed. This value can be set with
|
||||
outlierThreshold=<value> or -j <value>.
|
||||
* Correct for clock skew between nodes - if skew greater than wallclock
|
||||
deviation threshold (WC_DEV_THRESHOLD) in seconds, then broadcast root
|
||||
node's timestamp and adjust by the difference. WC_DEV_THRESHOLD currently
|
||||
set to 5.
|
||||
* Added a Users Guide.

|

To use these options, modify USE_UNDOC_OPT=TRUE in iordef.h and then recompile.
|
||||
For passing arguments to the executable for these options, use this format:
|
||||
|
||||
'-O option1=1,option2=0'
|
||||
|
||||
Options:
|
||||
|
||||
* fillTheFileSystem -- limits unnecessary output for showing performance, etc.
|
||||
The command line '-w -k -m -i 123 -F -O fillTheFileSystem=5' has each task
|
||||
creating (and keeping) 123 files, showing the time between every fifth file.
|
||||
|
||||
* includeDeleteTime -- use with '-O includeDeleteTime=1' to have time to
|
||||
delete file included in write performance time. Note that if this file
|
||||
is deleted after the write, there's nothing available for the read back
|
||||
or checking.
|
||||
|
||||
* multiReRead -- use with '-i 5 -v -k -w -W -O multiReRead=1' to have 1 write
|
||||
of file, followed by 4 reads w/data checking.
|
||||
|
||||
* NFS_serverCount -- use with other NFS_* options, -F, and -o to write/read
|
||||
files across multiple NFS servers. Set the server count to > 0 to enable.
|
||||
The format is: 'NFS_rootPath/NFS_serverName[0..NFS_serverCount-1]/outFile'.
|
||||
Each file is written round-robin to a different NFS server.
|
||||
|
||||
* NFS_rootPath -- use with NFS_server* options for path to NFS servers.
|
||||
|
||||
* NFS_serverName -- ise with NFS_* options for NFS server prefix. Specific
|
||||
NFS server number is appended to this name, e.g. nfs123.
|
||||
|
||||
* corruptFile -- corrupts file after writing for determining data-checking
|
||||
reliability.
|
||||
|
||||
Note:
|
||||
|
||||
* cbif.c (Change Byte In File) is a simple utility to check the value of
|
||||
a file offset; also allows changing a single byte at an offset.

* 1. DESCRIPTION *
|
||||
*******************
|
||||
IOR can be used for testing performance of parallel file systems using various
|
||||
interfaces and access patterns. IOR uses MPI for process synchronization.
|
||||
IOR version 2 is a complete rewrite of the original IOR (Interleaved-Or-Random)
|
||||
version 1 code.
|
||||
|
||||
|
||||
*******************
|
||||
* 2. BUILDING IOR *
|
||||
*******************
|
||||
Build Instructions:
|
||||
|
||||
Type 'gmake [posix|mpiio|hdf5|ncmpi|all]' from the IOR/ directory.
|
||||
On some platforms, e.g., Cray XT, specify "CC=cc" to build using "cc" instead of "mpicc".
|
||||
In IOR/src/C, the file Makefile.config currently has settings for AIX, Linux,
|
||||
OSF1 (TRU64), and IRIX64 to model on. Note that MPI must be present for
|
||||
building/running IOR, and that MPI I/O must be available for MPI I/O, HDF5,
|
||||
and Parallel netCDF builds. As well, HDF5 and Parallel netCDF libraries are
|
||||
necessary for those builds. All IOR builds include the POSIX interface.
|
||||
|
||||
You can build IOR as a native Windows application. One way to do this is to
|
||||
use the "Microsoft Windows SDK", which is available as a free download and
|
||||
includes development tools like the Visual C++ compiler. To build IOR with
|
||||
MPI-IO support, also download and install the "Microsoft HPC Pack SDK".
|
||||
Once these packages are installed on your Windows build system, follow these
|
||||
steps:
|
||||
1. Open a "CMD Shell" under the Start menu Microsoft Windows SDK group.
|
||||
2. cd to the IOR directory containing ior.vcproj
|
||||
3. Run: vcbuild ior.vcproj "Release|x64"
|
||||
|
||||
ior.exe will be created in the directory IOR/x64/Release. "Debug|x64",
|
||||
"Release|Win32", and "Debug|Win32" configurations can also be built.
|
||||
To build IOR without MPI-IO support, first edit ior.vcproj and replace
|
||||
aiori-MPIIO.c with aiori-noMPIIO.c.
|
||||
|
||||
|
||||
******************
|
||||
* 3. RUNNING IOR *
|
||||
******************
|
||||
Two ways to run IOR:
|
||||
|
||||
* Command line with arguments -- executable followed by command line options.
|
||||
|
||||
E.g., to execute: IOR -w -r -o filename
|
||||
This performs a write and a read to the file 'filename'.
|
||||
|
||||
* Command line with scripts -- any arguments on the command line will
|
||||
establish the default for the test run, but a script may be used in
|
||||
conjunction with this for varying specific tests during an execution of the
|
||||
code.
|
||||
|
||||
E.g., to execute: IOR -W -f script
|
||||
This defaults all tests in 'script' to use write data checking.
|
||||
|
||||
|
||||
**************
|
||||
* 4. OPTIONS *
|
||||
**************

*********************
|
||||
* 5. OPTION DETAILS *
|
||||
*********************
|
||||
For each of the general settings, note the default is shown in brackets.
|

||||
|
||||
GENERAL:
|
||||
========
|
||||
* testNum - test reference number for some output [-1]
|
||||
|
||||
* api - must be set to one of POSIX, MPIIO, HDF5, or NCMPI
|
||||
depending on test [POSIX]
|
||||
|
||||
* testFile - name of the output file [testFile]
|
||||
NOTE: with filePerProc set, the tasks can round
|
||||
robin across multiple file names '-o S@S@S'
|
||||
|
||||

|
||||
file-per-process modes; i.e. each iteration creates
|
||||

||||
|
||||
* reorderTasksConstant - reorders tasks by a constant node offset for writing/reading neighbor's
|
||||
data from different nodes [0=FALSE]
|
||||
|
||||
* taskPerNodeOffset - for read tests. Use with -C & -Z options. [1]
|
||||
With reorderTasks, constant N. With reordertasksrandom, >= N
|
||||
|
||||
* reorderTasksRandom - reorders tasks to random ordering for readback [0=FALSE]
|
||||
|
||||
* reorderTasksRandomSeed - random seed for reordertasksrandom option. [0]

>0, same seed for all iterations. <0, different seed for each iteration
|
||||
|
||||
* quitOnError - upon error encountered on checkWrite or checkRead,

||||
|
||||
* numTasks - number of tasks that should participate in the test
|
||||
[0]
|
||||
NOTE: 0 denotes all tasks
|
||||
|
||||
* interTestDelay - this is the time in seconds to delay before
|
||||
beginning a write or read in a series of tests [0]
|
||||
NOTE: it does not delay before a check write or
|
||||
check read
|
||||
|
||||
* outlierThreshold - gives warning if any task is more than this number
|
||||
of seconds from the mean of all participating tasks.
|
||||
If so, the task is identified, its time (start,
|
||||
elapsed create, elapsed transfer, elapsed close, or
|
||||
end) is reported, as is the mean and standard
|
||||
deviation for all tasks. The default for this is 0,
|
||||
which turns it off. If set to a positive value, for
|
||||
example 3, any task not within 3 seconds of the mean
|
||||
displays its times. [0]

||||
|
||||
* intraTestBarriers - use barrier between open, write/read, and close [0=FALSE]

file-per-process [0=FALSE]
|
||||
|
||||
* writeFile - writes file(s), first deleting any existing file [1=TRUE]
|
||||
NOTE: the defaults for writeFile and readFile are
|
||||
set such that if there is not at least one of
|
||||
the following -w, -r, -W, or -R, it is assumed
|
||||
that -w and -r are expected and are
|
||||
consequently used -- this is only true with
|
||||
the command line, and may be overridden in
|
||||
a script
|
||||
|
||||
* readFile - reads existing file(s) (from current or previous
|
||||
run) [1=TRUE]
|
||||
NOTE: see writeFile notes
|
||||
|
||||
* filePerProc - accesses a single file for each processor; default
|
||||
is a single file accessed by all processors [0=FALSE]
|
||||
|
||||
* checkWrite - read data back and check for errors against known
|
||||
pattern; can be used independently of writeFile [0=FALSE]
|
||||
NOTES: * data checking is not timed and does not
|
||||
affect other performance timings
|
||||
* all errors tallied and returned as program
|
||||
exit code, unless quitOnError set
|
||||
|
||||
* checkRead - reread data and check for errors between reads; can
|
||||
be used independently of readFile [0=FALSE]
|

|
||||
the error-filled file(s) will not be deleted [0=FALSE]
|
||||
|
||||
* useExistingTestFile - do not remove test file before write access [0=FALSE]
|
||||
|
||||
* segmentCount - number of segments in file [1]
|
||||
NOTES: * a segment is a contiguous chunk of data
|
||||
accessed by multiple clients each writing/
|
||||
reading their own contiguous data;
|
||||
comprised of blocks accessed by multiple
|
||||
clients
|
||||
* with HDF5 this repeats the pattern of an
|
||||
entire shared dataset
|
||||
|
||||
* blockSize - size (in bytes) of a contiguous chunk of data
|
||||
accessed by a single client; it is comprised of one
|
||||
or more transfers [1048576]
|
||||
|
||||
* transferSize - size (in bytes) of a single data buffer to be
|
||||
transferred in a single I/O call [262144]
|
||||
|
||||
* verbose - output information [0]
|
||||
NOTE: this can be set to levels 0-5 on the command
|
||||
line; repeating the -v flag will increase
|
||||
verbosity level
|
||||
|
||||
* setTimeStampSignature - set value for time stamp signature [0]
|
||||
NOTE: used to rerun tests with the exact data
|
||||
pattern by setting data signature to contain
|
||||
positive integer value as timestamp to be
|
||||
written in data file; if set to 0, is
|
||||
disabled
|
||||
|
||||
* showHelp - display options and help [0=FALSE]
|
||||
|
||||
* storeFileOffset - use file offset as stored signature when writing
|
||||
file [0=FALSE]
|
||||
NOTE: this will affect performance measurements
|
||||
|
||||
* maxTimeDuration - max time in minutes to run tests [0]
|
||||
NOTES: * setting this to zero (0) unsets this option
|
||||
* this option allows the current read/write
|
||||
to complete without interruption
|
||||
|
||||
* deadlineForStonewalling - seconds before stopping write or read phase [0]
|
||||
NOTES: * used for measuring the amount of data moved
|
||||
in a fixed time. After the barrier, each
|
||||
task starts its own timer, begins moving
|
||||
data, and the stops moving data at a pre-
|
||||
arranged time. Instead of measuring the
|
||||
amount of time to move a fixed amount of
|
||||
data, this option measures the amount of
|
||||
data moved in a fixed amount of time. The
|
||||
objective is to prevent tasks slow to
|
||||
complete from skewing the performance.
|
||||
* setting this to zero (0) unsets this option
|
||||
* this option is incompatible w/data checking
|
||||
|
||||
* randomOffset - access is to random, not sequential, offsets within a file [0=FALSE]
|
||||
NOTES: * this option is currently incompatible with:
|
||||
-checkRead
|
||||
-storeFileOffset
|
||||
-MPIIO collective or useFileView
|
||||
-HDF5 or NCMPI
|
||||
|
||||
|
||||
POSIX-ONLY:
|
||||
===========
|
||||
* useO_DIRECT - use O_DIRECT for POSIX, bypassing I/O buffers [0]
|
||||
|
||||
* singleXferAttempt - will not continue to retry transfer entire buffer
|
||||
until it is transferred [0=FALSE]
|
||||
NOTE: when performing a write() or read() in POSIX,
|
||||
there is no guarantee that the entire
|
||||
requested size of the buffer will be
|
||||
transferred; this flag keeps the retrying a
|
||||
single transfer until it completes or returns
|
||||
an error
|
||||
|
||||
* fsyncPerWrite - perform fsync after each POSIX write [0=FALSE]
|
||||
* fsync - perform fsync after POSIX write close [0=FALSE]
|
||||
|
||||
MPIIO-ONLY:
|
||||
===========
|
||||
* preallocate - preallocate the entire file before writing [0=FALSE]
|
||||
|
||||
* useFileView - use an MPI datatype for setting the file view option
|
||||
to use individual file pointer [0=FALSE]
|
||||
NOTE: default IOR uses explicit file pointers
|
||||
|
||||
* useSharedFilePointer - use a shared file pointer [0=FALSE] (not working)
|
||||
NOTE: default IOR uses explicit file pointers
|
||||
|
||||
* useStridedDatatype - create a datatype (max=2GB) for strided access; akin
|
||||
to MULTIBLOCK_REGION_SIZE [0] (not working)
|
||||
|
||||
HDF5-ONLY:
|
||||
==========
|
||||
* individualDataSets - within a single file each task will access its own
|
||||
dataset [0=FALSE] (not working)
|
||||
NOTE: default IOR creates a dataset the size of
|
||||
numTasks * blockSize to be accessed by all
|
||||
tasks
|
||||
|
||||
* noFill - no pre-filling of data in HDF5 file creation [0=FALSE]
|
||||
|
||||
* setAlignment - HDF5 alignment in bytes (e.g.: 8, 4k, 2m, 1g) [1]
|
||||
|
||||
MPIIO-, HDF5-, AND NCMPI-ONLY:
|
||||
==============================
|
||||
* collective - uses collective operations for access [0=FALSE]
|
||||
|
||||
* showHints - show hint/value pairs attached to open file [0=FALSE]
|
||||
NOTE: not available in NCMPI
|
||||
|
||||
LUSTRE-SPECIFIC:
|
||||
================
|
||||
* lustreStripeCount - set the lustre stripe count for the test file(s) [0]
|
||||
|
||||
* lustreStripeSize - set the lustre stripe size for the test file(s) [0]
|
||||
|
||||
* lustreStartOST - set the starting OST for the test file(s) [-1]
|
||||
|
||||
* lustreIgnoreLocks - disable lustre range locking [0]
|
||||
|
||||
|
||||
***********************
|
||||
* 6. VERBOSITY LEVELS *
|
||||
***********************
|
||||
The verbosity of output for IOR can be set with -v. Increasing the number of
|
||||
-v instances on a command line sets the verbosity higher.
|
||||
|
||||
Here is an overview of the information shown for different verbosity levels:
|
||||
0 - default; only bare essentials shown
|
||||
1 - max clock deviation, participating tasks, free space, access pattern,
|
||||
commence/verify access notification w/time
|
||||
2 - rank/hostname, machine name, timer used, individual repetition
|
||||
performance results, timestamp used for data signature
|
||||
3 - full test details, transfer block/offset compared, individual data
|
||||
checking errors, environment variables, task writing/reading file name,
|
||||
all test operation times
|
||||
4 - task id and offset for each transfer
|
||||
5 - each 8-byte data signature comparison (WARNING: more data to STDOUT
|
||||
than stored in file, use carefully)
|
||||
|
||||
|
||||
********************
|
||||
* 7. USING SCRIPTS *
|
||||
********************
|
||||
|
||||
IOR can use a script with the command line. Any options on the command line
|
||||
will be considered the default settings for running the script. (I.e.,
|
||||
'IOR -W -f script' will have all tests in the script run with the -W option as
|
||||
default.) The script itself can override these settings and may be set to run
|
||||
run many different tests of IOR under a single execution. The command line is:
|
||||
|
||||
IOR/bin/IOR -f script
|
||||
|
||||
In IOR/scripts, there are scripts of testcases for simulating I/O behavior of
|
||||
various application codes. Details are included in each script as necessary.
|
||||

****************************************
|
||||
* 8. COMPATIBILITY WITH OLDER VERSIONS *
|
||||
****************************************
|
||||
1) IOR version 1 (c. 1996-2002) and IOR version 2 (c. 2003-present) are
|
||||
incompatible. Input decks from one will not work on the other. As version
|
||||
1 is not included in this release, this shouldn't be case for concern. All
|
||||
subsequent compatibility issues are for IOR version 2.
|
||||
|
||||
2) IOR versions prior to release 2.8 provided data size and rates in powers
|
||||
of two. E.g., 1 MB/sec referred to 1,048,576 bytes per second. With the
|
||||
IOR release 2.8 and later versions, MB is now defined as 1,000,000 bytes
|
||||
and MiB is 1,048,576 bytes.
|
||||
|
||||
3) In IOR versions 2.5.3 to 2.8.7, IOR could be run without any command line
|
||||
options. This assumed that if both write and read options (-w -r) were
|
||||
omitted, the run with them both set as default. Later, it became clear
|
||||
that in certain cases (data checking, e.g.) this caused difficulties. In
|
||||
IOR versions 2.8.8 and later, if not one of the -w -r -W or -R options is
|
||||
set, then -w and -r are set implicitly.

|
||||
-k keeps the file after the access rather than deleting it
|
||||
-E uses the existing file rather than truncating it first
|
||||
-W performs the writecheck
|
||||
-i number of iterations of checking
|
||||
-o filename
|
||||
|
||||
On versions of IOR prior to 2.8.8, you need the -r flag also, otherwise
|
||||
you'll first overwrite the existing file. (In earlier versions, omitting -w
|
||||
and -r implied using both. This semantic has been subsequently altered to be
|
||||
omitting -w, -r, -W, and -R implied using both -w and -r.)
|
||||
|
||||
If you're running new tests to create a file and want repeat data checking on
|
||||
this file multiple times, there is an undocumented option for this. It's -O
|
||||
multiReRead=1, and you'd need to have an IOR version compiled with the
|
||||
USE_UNDOC_OPT=1 (in iordef.h). The command line would look like this:
|
||||
|
||||
IOR -k -E -w -W -i 5 -o file -O multiReRead=1
|
||||
|
||||
For the first iteration, the file would be written (w/o data checking). Then
|
||||
for any additional iterations (four, in this example) the file would be
|
||||
reread for whatever data checking option is used.
|
||||
|
||||
|
||||
HOW DOES IOR CALCULATE PERFORMANCE?
|
||||
|
||||
IOR performs get a time stamp START, then has all participating tasks open a
|
||||
shared or independent file, transfer data, close the file(s), and then get a
|
||||
STOP time. A stat() or MPI_File_get_size() is performed on the file(s) and
|
||||
compared against the aggregate amount of data transferred. If this value
|
||||
does not match, a warning is issued and the amount of data transferred as
|
||||
calculated from write(), e.g., return codes is used. The calculated
|
||||
bandwidth is the amount of data transferred divided by the elapsed
|
||||
STOP-minus-START time.
|
||||
|
||||
IOR also gets time stamps to report the open, transfer, and close times.
|
||||
Each of these times is based on the earliest start time for any task and the
|
||||
latest stop time for any task. Without using barriers between these
|
||||
operations (-g), the sum of the open, transfer, and close times may not equal
|
||||
the elapsed time from the first open to the last close.
|
||||
|
||||
|
||||
HOW DO I ACCESS MULTIPLE FILE SYSTEMS IN IOR?
|
||||
|
||||
It is possible when using the filePerProc option to have tasks round-robin
|
||||
across multiple file names. Rather than use a single file name '-o file',
|
||||
additional names '-o file1@file2@file3' may be used. In this case, a file
|
||||
per process would have three different file names (which may be full path
|
||||
names) to access. The '@' delimiter is arbitrary, and may be set in the
|
||||
FILENAME_DELIMITER definition in iordef.h.
|
||||
|
||||
Note that this option of multiple filenames only works with the filePerProc
|
||||
-F option. This will not work for shared files.
|
||||
|
||||
|
||||
HOW DO I BALANCE LOAD ACROSS MULTIPLE FILE SYSTEMS?
|
||||
|
||||
As for the balancing of files per file system where different file systems
|
||||
offer different performance, additional instances of the same destination
|
||||
path can generally achieve good balance.
|
||||
|
||||
For example, with FS1 getting 50% better performance than FS2, set the '-o'
|
||||
flag such that there are additional instances of the FS1 directory. In this
|
||||
case, '-o FS1/file@FS1/file@FS1/file@FS2/file@FS2/file' should adjust for
|
||||
the performance difference and balance accordingly.
|
||||
|
||||
|
||||
HOW DO I USE STONEWALLING?
|
||||
|
||||
To use stonewalling (-D), it's generally best to separate write testing from
|
||||
read testing. Start with writing a file with '-D 0' (stonewalling disabled)
|
||||
to determine how long the file takes to be written. If it takes 10 seconds
|
||||
for the data transfer, run again with a shorter duration, '-D 7' e.g., to
|
||||
stop before the file would be completed without stonewalling. For reading,
|
||||
it's best to create a full file (not an incompletely written file from a
|
||||
stonewalling run) and then run with stonewalling set on this preexisting
|
||||
file. If a write and read test are performed in the same run with
|
||||
stonewalling, it's likely that the read will encounter an error upon hitting
|
||||
the EOF. Separating the runs can correct for this. E.g.,
|
||||
|
||||
IOR -w -k -o file -D 10 # write and keep file, stonewall after 10 seconds
|
||||
IOR -r -E -o file -D 7 # read existing file, stonewall after 7 seconds
|
||||
|
||||
Also, when running multiple iterations of a read-only stonewall test, it may
|
||||
be necessary to set the -D value high enough so that each iteration is not
|
||||
reading from cache. Otherwise, in some cases, the first iteration may show
|
||||
100 MB/s, the next 200 MB/s, the third 300 MB/s. Each of these tests is
|
||||
actually reading the same amount from disk in the allotted time, but they
|
||||
are also reading the cached data from the previous test each time to get the
|
||||
increased performance. Setting -D high enough so that the cache is
|
||||
overfilled will prevent this.
|
||||
|
||||
|
||||
HOW DO I BYPASS CACHING WHEN READING BACK A FILE I'VE JUST WRITTEN?
|
||||
|
||||
One issue with testing file systems is handling cached data. When a file is
|
||||
written, that data may be stored locally on the node writing the file. When
|
||||
the same node attempts to read the data back from the file system either for
|
||||
performance or data integrity checking, it may be reading from its own cache
|
||||
rather from the file system.
|
||||
|
||||
The reorderTasks '-C' option attempts to address this by having a different
|
||||
node read back data than wrote it. For example, node N writes the data to
|
||||
file, node N+1 reads back the data for read performance, node N+2 reads back
|
||||
the data for write data checking, and node N+3 reads the data for read data
|
||||
checking, comparing this with the reread data from node N+4. The objective
|
||||
is to make sure on file access that the data is not being read from cached
|
||||
data.
|
||||
|
||||
Node 0: writes data
|
||||
Node 1: reads data
|
||||
Node 2: reads written data for write checking
|
||||
Node 3: reads written data for read checking
|
||||
Node 4: reads written data for read checking, comparing with Node 3
|
||||
|
||||
The algorithm for skipping from N to N+1, e.g., expects consecutive task
|
||||
numbers on nodes (block assignment), not those assigned round robin (cyclic
|
||||
assignment). For example, a test running 6 tasks on 3 nodes would expect
|
||||
tasks 0,1 on node 0; tasks 2,3 on node 1; and tasks 4,5 on node 2. Were the
|
||||
assignment for tasks-to-node in round robin fashion, there would be tasks 0,3
|
||||
on node 0; tasks 1,4 on node 1; and tasks 2,5 on node 2. In this case, there
|
||||
would be no expectation that a task would not be reading from data cached on
|
||||
a node.
|
||||
|
||||
|
||||
HOW DO I USE HINTS?
|
||||
|
||||
It is possible to pass hints to the I/O library or file system layers
|
||||
following this form:
|
||||
'setenv IOR_HINT__<layer>__<hint> <value>'
|
||||
For example:
|
||||
'setenv IOR_HINT__MPI__IBM_largeblock_io true'
|
||||
'setenv IOR_HINT__GPFS__important_hint true'
|
||||
or, in a file in the form:
|
||||
'IOR_HINT__<layer>__<hint>=<value>'
|
||||
Note that hints to MPI from the HDF5 or NCMPI layers are of the form:
|
||||
'setenv IOR_HINT__MPI__<hint> <value>'
|
||||
|
||||
|
||||
HOW DO I EXPLICITY SET THE FILE DATA SIGNATURE?
|
||||
|
||||
The data signature for a transfer contains the MPI task number, transfer-
|
||||
buffer offset, and also timestamp for the start of iteration. As IOR works
|
||||
with 8-byte long long ints, the even-numbered long longs written contain a
|
||||
32-bit MPI task number and a 32-bit timestamp. The odd-numbered long longs
|
||||
contain a 64-bit transferbuffer offset (or file offset if the '-l'
|
||||
storeFileOffset option is used). To set the timestamp value, use '-G' or
|
||||
setTimeStampSignature.
|
||||
|
||||
|
||||
HOW DO I EASILY CHECK OR CHANGE A BYTE IN AN OUTPUT DATA FILE?
|
||||
|
||||
There is a simple utility IOR/src/C/cbif/cbif.c that may be built. This is a
|
||||
stand-alone, serial application called cbif (Change Byte In File). The
|
||||
utility allows a file offset to be checked, returning the data at that
|
||||
location in IOR's data check format. It also allows a byte at that location
|
||||
to be changed.
|
||||
|
||||
|
||||
HOW DO I CORRECT FOR CLOCK SKEW BETWEEN NODES IN A CLUSTER?
|
||||
|
||||
To correct for clock skew between nodes, IOR compares times between nodes,
|
||||
then broadcasts the root node's timestamp so all nodes can adjust by the
|
||||
difference. To see an egregious outlier, use the '-j' option. Be sure
|
||||
to set this value high enough to only show a node outside a certain time
|
||||
from the mean.
|
||||
|
||||
|
||||
WHAT HAPPENED TO THE GUI?
|
||||
|
||||
In versions of IOR earlier than 2.9.x, there was a GUI available. Over time
|
||||
it became clear that it wasn't find enough use to warrant maintenance. It
|
||||
was retired in IOR-2.10.x.

Output Statistics:
|
||||
|
||||
The quantity "aggregate operations/sec" was added to the existing "aggregate data rate" test log print file.
|
||||
An "operation" is defined to be a write or read within an open/close [open/write|read/close].
|
||||
Multiple writes or reads within an open/close are also counted as multiple operations.
|
||||
Also various other test relevant quantities are printed on a single "grepable" line using the pattern EXCEL.
|
||||
This way, output from large parameter space runs can easily be imported to excel for analysis. Below is an example.

/* Describe the long-named options requested by the application.
|
||||
The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
|
||||
of `struct option' terminated by an element containing a name which is
|
||||
zero.
|
||||
|
||||
The field `has_arg' is:
|
||||
no_argument (or 0) if the option does not take an argument,
|
||||
required_argument (or 1) if the option requires an argument,
|
||||
optional_argument (or 2) if the option takes an optional argument.
|
||||
|
||||
If the field `flag' is not NULL, it points to a variable that is set
|
||||
to the value given in the field `val' when the option is found, but
|
||||
left unchanged if the option is not found.
|
||||
|
||||
To have a long-named option do something other than set an `int' to
|
||||
a compiled-in constant, such as set a value from `optarg', set the
|
||||
option's `flag' field to zero and its `val' field to a nonzero
|
||||
value (the equivalent single-letter option character, if there is
|
||||
one). For long options that have a zero `flag' field, `getopt'
|
||||
returns the contents of the `val' field. */

|
||||
there are no more options. For unrecognized options, or options
|
||||
missing arguments, `optopt' is set to the option letter, and '?' is
|
||||
returned.
|

|
||||
The OPTS string is a list of characters which are recognized option
|
||||
letters, optionally followed by colons, specifying that that letter
|
||||
takes an argument, to be placed in `optarg'.
|
||||
|
||||
If a letter in OPTS is followed by two colons, its argument is
|
||||
optional. This behavior is specific to the GNU `getopt'.
|
||||
|
||||
The argument `--' causes premature termination of argument
|
||||
scanning, explicitly telling `getopt' that there are no more
|
||||
options.
|
||||
|
||||
If OPTS begins with `--', then non-option arguments are treated as

||||
arguments to the option '\0'. This behavior is specific to the GNU
|

`getopt'. */

The IOR-tester runs a series of tests to check and maintain the existing
|
||||
functionality of the source code as code is modified. The IOR-tester creates
|
||||
a default test, then modifies it to run test scripts. It runs a large number
|
||||
of tests, most which are expected to pass, but some with an expectation of
|
||||
failure.
|
||||
|
||||
To run the code, modify the 'DefaultTest' dictionary in the source code to
|
||||
reflect the test file location, the executable location, etc. Then, run
|
||||
the code using './IOR-tester.py'.
|
||||
|
||||
The expected-pass, pattern-independent tests include:
|
||||
POSIX only:
|
||||
o retry transfer
|
||||
|
||||
MPIIO only:
|
||||
o hints
|
||||
o preallocation
|
||||
|
||||
Both POSIX and MPIIO:
|
||||
o repetition count
|
||||
o intertest delay
|
||||
o test file removal
|
||||
o verbosity
|
||||
|
||||
The expected-pass, pattern-dependent tests include:
|
||||
POSIX:
|
||||
o write-only, read-only, write/read, and write/read check
|
||||
o fpp and single file
|
||||
o segmented, strided
|
||||
o zero-length, 4-byte, and larger file, block, and transfer sizes
|
||||
MPIIO (same as POSIX, but using MPIIO access):
|
||||
o noncollective
|
||||
o noncollective, file view
|
||||
o collective
|
||||
o collective, file view
|
