Adding general MPI derived datatype testing code.
Description:
The testing code will not be tested. The purpose of checking in is for
better debugging later. HDF5 routine or daily test should not be aware of this.
Solution:
Platforms tested:
Copper(AIX 5.1),
Heping(Linux 2.4 + MPICH 1.2.6).
Misc. update:
Bug fix
Description:
Relax restrictions on parallel I/O to allow compressed, chunked datasets
to be read in parallel (collective access will be degraded to independent
access, but will retrieve the information still).
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Solaris 2.7 (arabica)
IRIX64 6.5 (modi4)
h5committest
Code clean up
Description:
The tests used to have their own test file names due to
the original program layout. Now that it is using the
common test interface, individual test can be invoked
at will (via -o). There is no need to have different
test filenames. Only requirement is that certain read
tests must follow immediately the corresponding write
test since they use the same file.
I have combined all test file names into just one common
file name. This reduces the printout of test file name,
very beneficial when the test is run by large number of processes.
It makes future code maintenance easier too.
Platforms tested:
Tested in Eirene(PP) only. No h5committest because this is
limited to the parallel tests and the changes are trivial.
Misc. update:
Add test to verify the fix of the parallel I/O mode confusion bug.
Description:
While the parallel I/O mode confusion bug is fixed, an automated
regression test for this bug would be useful.
Solution:
Added a modified version of the original bug demonstration program
to testphdf5.
Platforms tested:
copper
h5committested
eirene (parallel)
Misc. update:
Code cleanup
Description:
Tweak recent "forward compatibility" changes to the H5E* API (which allowed
for the old H5E API functions to remain unchanged) by allowing for the error
stack callback function (H5E_auto_t) to also remain unchanged from the 1.6
branch. This required changing the H5E{get|set}_auto routines to have the
old style H5E_auto_t type (which didn't have a stack ID parameter) and the new
H5E{get|set}_auto_stack routines to have a newer "H5E_auto_stack_t" type (which
has a stack ID parameter). This should make the H5E API changes as forwardly
compatible as possible.
One side-affect of this change was that it was impossible to determine if
the current auto error callback was the old style (H5E_auto_t) or the new style
(H5E_auto_stack_t) of callback, so a new API function (H5Eauto_is_stack) was
adde to query this.
Platforms tested:
FreeBSD 4.10 (sleipnir)
IRIX64 6.5 (modi4)
h5committest
Purpose:
Shrink HDF5 parallel test
Description:
Previously the collective chunk IO tests created and opened four HDF5 files;
it turned out that all collective chunk IO tests can use one file for testing.
Solution:
To use one file for all collective chunk IO tests with trunc option to be set in H5Fcreate.
Platforms tested:
copper(no need to use h5committest)
Misc. update:
Text display change
Description:
Changed the test names to much shorter strings for easier
use.
Platforms tested:
No h5committed test. Only test parallel in eirene.
Misc. update:
Code cleanup.
Removed bunch of old options (r,w,v,i,b,e) that are no longer valid
or useful after adopting the general test interface. Moved the test
of sizeof MPI_Offset into the test routine itself.
Platforms tested:
Eirene and Sol using pp mode.
bug fix.
Description:
The test routines only print error messages but not all of them
return number of errors detected back to the main routine which
always exit with a 0 status. Thus make or shell commands could
not detect there were errors.
Solution:
Changed the test routines to return appropriate number of
errors to main routine which in turn exit with the appropriate
exit code if errors found.
Platforms tested:
Tested in Sol and eirene (pp).
Misc. update:
feature
Description:
Another revamp of the test interface.
TestInit: is used to register Test Program name, test program specific
Usage and option parsing routines.
TestUsage: will invoke extra usage routine if provided.
TestParseCmdLine: will invoke extra option parsing routine if provided.
GetTestSummary() and GetTestCleanup() replaces the previous Summary and
CleanUp arguments of TestParseCmdLine.
test/testhdf5, test/ttsafe.c, testpar/t_mpi.c, testpar/testphdf5.c:
All have been updated to use the new Test Routines.
testpar/t_mpi.c:
Also a fix of a compiler optimization bug when pgcc in Linux is
used to compile it. Changed buf[] and expected to unsigned char
type to avoid a bug that failed to do sign-extension.
Platforms tested:
"h5committested"
Also tested thread-safe option in eirene.
Purpose:
bug fix
Description:
1. The IF-block of skipping collective chunk IO tests when the number of
processes is greater than some number essentially skipped all parallel tests.
2. John tested at copper with the number of processor = 64 and collective
chunk IO tests passed, so we increase the number of precessor =24 to 64 for
skipping the test.
Solution:
1. change the IF block flow so that it only skips collective chunk IO tests when
the number of process is greater than 64.
Platforms tested:
copper(only change a bit of parallel test code, no needs to test on other platforms).
Misc. update:
Correction of the previous check.
Description:
forget moving "debug #if macro" out of this file.
Solution:
remove that "#if 0 #endif" macro block.
Platforms tested:
Compile at eirene
Too trivial to test
Misc. update:
Better collective chunk IO test arrangements
Description:
collective chunk IO tests have been verified with the number of process greater than 24 and
the test is very slow with big number of process.
That may cause confusions to users who run collective chunk IO tests.
Solution:
To avoid possible confusions, A if-block will be used to check whether the number of process
is greater than 24. If yes, the collective chunk tests will be skipped and a message will be printed out.
Platforms tested:
linux 2.4
(too trivial to use h5committest)
Misc. update:
Cleanup and bug fix.
Description:
Bug fix:
the checking of dobig test was done in the wrong place
such that tests added after it would be run even for the -b option.
Moved the dobig test checking to AFTER all tests are added.
Cleanup:
Removed old code now that the new way is working fine.
Platforms tested:
Tested in Eirene parallel only.
Misc. update:
Feature
Description:
Added a feature such that if the test name starts with '-', do not run it
by default.
Platforms tested:
Eirene both serial and parallel.
Misc. update:
Code cleanup
Description:
Fix another batch of minor differences between the development and release
branches.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest
Code cleanup
Description:
Clean up collective chunking code a bit.
Also, add '--enable-instrument' configure flag to have a mechanism for
determining that optimized operations happened correctly in the library (instead
of just the "normal" way) by allowing 'flag' properties to be set outside the
library and set when the "right" thing happens. This is mainly for debugging
and regression checks, so we make certain we don't break optimized I/O by
accident. It's enabled by default when --enable-debug is on (which is on by
default in the development branch and off by default in the release branch),
but can also be independently controlled with its own configure flag.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
IBM p690 (copper) w/parallel
To test collective chunk IO properly.
Description:
See the previous message.
Solution:
See the previous message.
Platforms tested:
arabica(Sol 2.7), eirene(Linux), copper(AIX)
Misc. update:
To add collective chunk IO tests.
Description:
three tests are added.
1. Only one hyperslab for each process, and this hyperslab is fit in exactly one chunk.
2. non-contiguous hyperslabs in each process, these hyperslabs are fit in one chunk.
3. Single hyperslab for each process, smaller chunk is assigned. Number of chunks for
every process is equal.
Solution:
the dataset size is set to be very small, will enlarge later.
Platforms tested:
AIX 5.1(copper)
Misc. update:
Bug fix
Description:
Fix error in chunked dataset I/O where data written out wasn't read
correctly from a chunked, extendible dataset after the dataset was extended.
Also, fix parallel I/O tests to gather error results from all processes,
in order to detect errors that only occur on one process.
Solution:
Bypass chunk cache for reads as well as writes, if parallel I/O driver is
used and file is opened for writing.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest
feature
Description:
Change testphdf5 to use the common test program syntax.
Needed to change the protocols of all test programs to
fit the requirement of the common test syntax.
Platforms tested:
"h5committested".
Also tested in sol with PP mode.
Improvement
Description:
Changed parsing of verbose level by the common test library routine.
Change t_mpi.c to use the Verbose control better.
Platforms tested:
verena (pp).
Misc. update:
Improvement.
Description:
Complete change of the verbose control to use the routines provided by
the test/libh5test.a.
Also put in a temporary fix for the H5Eset_auto() and H5Eget_auto()
so that the Compat code are isolated in one place rather than all over
the source file.
Platforms tested:
Tested in Eirene (parallel).
Misc. update:
Added a test of fill value before any data is written to a dataset.
Rename short_dataset() as dataset_fillvalue() as it reflects better
the tests. Also removed the option of -S since the fill value test
will be tested always.
Platforms tested:
"h5committested"
Misc. update:
Feature.
Description:
Added the short_dataset test (was in v1.6 first.)
Platforms tested:
Tested in eirene (pp) only since these have been tested in v1.6 already.
Misc. update:
Feature, sort of.
Description:
Reactivated the big dataset test. Changed it
to default off, can be turned on via -b.
Platforms tested:
Only in Copper which is the only local machine safe to run
mulitple GB size files.
Misc. update:
Disable "big" parallel tests until I get a chance to look into the
problems (probably during/after the workshop).
Platforms tested:
Eyeballed
Too minor to require h5committest
Bug fix
Description:
The MPI_File_set_size() routine on ASCI Red is not able to extend files
so that they are larger than 2GB.
Solution:
Add an extra macro which controls whether MPI_File_set_size() can handle
>2GB offsets or if our "older" way of reading a byte, then writing a byte at
the appropriate offset should be used.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
Compatibility fix
Description:
The H5P[set|get]_fapl_mpiposix calls changed between v1.4.x and v1.5.x.
Solution:
Wrap them in the v1.4 backward compatibility #ifdefs and update tests, etc.
Platforms tested:
FreeBSD 4.8 (sleipnir) w/paralle & v1.4 compatibility
h5committest pointless
Add printout to identify when the MPIPOSIX driver is being tested instead
of the MPI-IO driver..
Platforms tested:
Tested in copper in parallel mode only since it was just a simple
print statement in the parallel test code.
Misc. update:
Feature Add
Description:
Added knob so that the programmer can enable or disable GPFS
hints during runtime instead of having it only enabled at
configure/compile time. Some of the public APIs were changed
to add an extra parameter for this option...
Platforms tested:
Blue (LLNL). It only affects the MPI/POSIX driver, so no need
to test it on non-GPFS platforms.
Misc. update:
feature
Description:
added test_fapl_mpiposix_dup to verify the MPIPOSIX is making
duplicates of Communicator correctly.
Platforms tested:
Did not h5committested because these are all MPI code and well protected
by HAVE_PARALLEL.
Tested in eirene and modi4, both parallel mode.
Misc. update:
code cleanup.
Description:
Rename test_comm_info_delete to test_fapl_mpio_dup to better decribe
what it does. Updated the comments to describe more accurate.
Platforms tested:
Did not run h5commmittest since the changes were all in parallel area.
Ran parallel tests on modi4 and eirene.
Misc. update:
Bug fixes/API changes
Description:
Previously, the Communicator and Info object arguments supplied
to H5Pset_fapl_mpio() are stored in the property with its handle
values. This meant changes to the communicator or the Info object
after calling H5Pset_fapl_mpio would affect the how the property
list function. This was also the case when H5Fopen/create operated.
They just stored the handle value. This is not according to the
MPI-2 defined behavior of how Info objects should be handled. (MPI-2
defines Info objects must be parsed when called.)
The old design was trying to avoid numerous duplicates of the same
information (e.g., every property object holds one version, every
file opened holds another version, when all of them are referring to
the same original version.) Nevertheless it is safer to implement
it according to MPI-2 definition.
Futhermore, the library often needs to do message passing using the
supplied communicator. Using the same communicator as the application
version may result in some messages mix up.
Solution:
H5Pset_fapl_mpio now stores a duplicate of each of the communicator
and Info object.
H5Pget_fapl_mpio returns a duplicate of its stored communicator and
Info object. It is now the responsibility of the applications to free
those objects when done.
H5Fopen/create also stores a duplicate of the communicator and Info
object supplied by the File Access Property list.
H5Fclose frees those duplicates.
There are a few more internal VFL call back functions that they
follow this "make duplicates" requirement.
Platforms tested:
"h5committested".
What other platforms/configurations were tested?
Eirene (mpicc), sol(mpicc), copper(parallel)
Misc. update:
Need to update MANIFEST for the added t_ph5basic.c which tests the
correctness of duplicated communicator and INFO object.
Update
Description:
Updated (and in some cases added) the copyright statement.
Platforms tested:
Linux (Comment changes...only tested if they compile)
Misc. update:
Purpose:
More test.
Description:
Test independent read of groups and chunked dataset.
Solution:
This test is similar to multiple group test. So just add it in the
testphdf5.c,h.
Platforms tested:
modi4, eirene.
Bug fix (no id, just noticed myself)
Description:
Added a barrier before doing file cleanup to ensure all tests are
completed by then.
Moved the MPI_Finalize to be very end and insert an H5close before
it to ensure all potential MPI activities by HDF5 are done by then.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}? Yes.
Code cleanup
Description:
Cleaned up some compiler warnings.
Platforms tested:
FreeBSD 4.6 (sleipnir) w/serial & parallel. Will be testing on IRIX64
6.5 (modi4) in serial & parallel shortly.
Purpose:
Design for compact dataset
Description:
Compact dataset is stored in the header message for dataset layout.
Platforms tested:
arabica, eirene.
Code cleanup
Description:
Platform dependent code related to the struct stat and fstat
calls polluted source codes. Hard to maintain.
Solution:
Platform dependent code are moved to H5private.h and then internal
code can #include H5private.h. Repeat those macro definition for
the stdio and multi drivers since they area examples for writing
a virtual file driver. They must not use any internal code.
Platforms tested:
eirene (parallel), modi4 (serial including gass driver.)
New test feature
Description:
Added create_faccess_plist() that create just MPIO or split+MPIO
file-access property list. This in turn can run parallel tests
with just MPIO or with Split-file VFD too.
Added -s option for split-file Plus MPIO tests.
For testphdf5.c: removed a bunch of old debug code that got left
in by mistake.
Platforms tested:
Modi4 and eirene parallel.
But it has uncovered errors in the library. The test program
is correct though. Checking the test program in so that it won't
get lost and can be used for debugging. Also, the -s is not used
by default during test. At least it won't abort "make check".
