IOR uses the GetTimeStamp() wrapper to allow gettimeofday() to be used for timings instead of MPI_Wtime() to calculate throughput. This commits adds the same logic to mdtest timings.
This patch enables correct compilation on both MacOS and Linux using only
POSIX.1-2008-compliant C with XSI extensions.
Specifically, POSIX.1-2008 is the minimum version because we use strdup(3);
explicit XSI is required to expose putenv from glibc.
Leading whitespace is stripped from each line of the ior input file. This
allows indented comments to be treated as comments. However it does NOT allow
one to specify excessive whitespace inside of the `ior start` and `ior stop`
magic phrases.
Also added a test to catch regressions in this functionality.
Context: Some backends may have used different names in
the past (like IME backend use to be IM). Legacy scripts
may break.
This patch adds a legacy name option in the aiori structure.
Both name and legacy name work to select the interface.
But the following warning is printed if the legacy name is used:
ior WARNING: [legacy name] backend is deprecated use [name] instead.
- travis now tests the packaged source to detect missing source/headers
- basic tests are less sensitive to the directory from where they are run
- fixed some missing files from the `make dist` manifest
- updated the format of NEWS to work with `make dist`
Context: write and read results from the same iteration
use the same length value in Bytes. When stonewalling is
used the size variates depending on the performance of
the access. This leads to wrong max bandwidths reported
for writes as shown in the following example:
write 10052 ...
read 9910 ...
write 10022 ...
read 9880 ...
write 10052 ...
read 9894 ...
Max Write: 9371.43 MiB/sec (9826.66 MB/sec)
Max Read: 9910.48 MiB/sec (10391.89 MB/sec)
This patch makes IOR separate variables used for read
and write tests.
Context: IOR outputs errors when the '-w -W' flags are used
without '-r'. Write a file using with check write option
should be possible even without setting read.
This patch fixes a condition which was introduced for
HDFS to remove RDWR flag in some particular cases.
Write check was set with the write only flag but it
requieres the read flag.
Context: IOR initializes all available backends. If one
backend fails to initialize IOR cannot be used.
This patch makes IOR initialize only the backends
which will be used. The initialization is done after
that the parameters are checked so that the help message
can still be dispayed is something goes wrong.
Context: IOR gets a segfault if an unsupported API string
is provided.
This patch checks that the I/O backend is supported, otherwise
IOR stops with an error.
