Version Compatibility
|
|
=====================
|
|
|
|
IOR has a long history and only IOR version 3 is currently supported. However,
|
|
there are many forks of IOR based on earlier versions, and the following
|
|
incompatibilities are known to exist between major 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.
|
|
|
|
4) IOR version 3 (Jan 2012-present) has changed the output of IOR somewhat,
|
|
and the "testNum" option was renamed "refNum".
