Update
Description:
This completes Phase I of the FPHDF5 testing. This test does the
following:
- Creates a file
- Creates multiple non-root groups
- For each process:
For each non-root group:
Create multiple datasets
Access all datasets created above
Write to all datasets created above
- Close the file
- Reopen the file and verify the data is correct
Platforms tested:
AIX (w/ FPHDF5)
Linux (w/ FPHDF5)
Solaris (w/ Fortran & C++)
Misc. update:
new feature.
Description:
Added tests of 1wMr with options to apply Atomicity or File_sync.
Platforms tested:
only tested in eirene and Teragrid as this is just an MPI test.
Misc. update:
Update
Description:
Extensive reworking of the code. More modular now. Tests for almost
all of "Phase 1"s requirements. Need to check that data is correct
after reopening the file.
Platforms tested:
Linux (w/ FPHDF5)
AIX (w/ and w/o FPHDF5)
FPHDF5-specific fixes...No need for H5committest
Misc. update:
new test.
Description:
Added test_mpio_1wMr test which verify if the file system can support
1 process writes, many processes read.
Platforms tested:
h5committested.
Misc. update:
Update
Description:
The FPHDF5 test now writes data simultaneously from all processes to
all created datasets. It's wicked cool!
Platforms tested:
Linux (w/ FPHDF5)
Copper (w/ FPHDF5 & w/o Parallel)
FPHDF5-specific, so no h5committest
Misc. update:
Update
Description:
Modified the FPHDF5 test so that a single process creates multiple
datasets in a non-root group then all of the processes (sans the SAP)
access it.
Modularized the code a bit more to make it easy to perform the above
tests.
Changed the code a bit so that >3 processes can (theoretically) be
used to test this.
Platforms tested:
Linux (FPHDF5 specific change)
Misc. update:
Update
Description:
Expanded the FPHDF5 test to include creating multiple datasets by one
process in a non-root group.
Cleaned up the code a bit more to make it more modular and easier to
work with.
Platforms tested:
Linux (FPHDF5 specific)
Misc. update:
Update
Description:
Added test for FPHDF5 to the testpar/ directory. If you specify
--enable-fphdf5 during configuration, it'll run this test during a
"make check".
Platforms tested:
Linux (FPHDF5 specific).
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:
Bug/feature fix.
Description:
Relax restriction on parallel writing to compact datasets to allow partial
I/O.
Updates to reference manual mentioning the issues involved are delayed until
reference manual 'lock' is removed later this week.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor to require h5committest
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
Bug fix
Description:
Temporary files were not cleaned out because the definiton of
temporary files had not been updated.
Solution:
Updated it.
Platforms tested:
Tested by hand in Copper while i was testing the MPE change.
Misc. update:
Updated the copyright notice--mostly by rearranging
some text to make them consistent.
Solution:
Platforms tested:
"h5committested"--sol is down, so, no SUn test.
Misc. update:
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
Bug fix
Description:
An earlier checkin changed some of the assumptions about single block
hyperslabs, causing them to fail in odd ways.
Solution:
Fix errors with single block hyperslabs by keying off of count==1 instead
of stride==1.
Platforms tested:
FreeBSD 4.8 (sleipnir) w/parallel
h5committested
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:
simple code cleanup.
Description:
While debug a problem in multiple_group_write(), noticed some returned
values were not checked. Added code to check on all returned code.
Platforms tested:
h5committested.
Misc. update:
bug fix
Description:
The fphdf5.o and similar files are not included in the make clean
target. So, if the same directory is used again for a different
build, the left behind file could cause a problem (e.g., if
the second build is for a different binary format.)
Solution:
Added fphdf5.c to the TEST_SRC list which indirect form the clean
target list.
Platforms tested:
Did not run h5committest tests because they don't verify this
failure. I tested the fix in modi4 pp to verify all files are cleaned.
Misc. update:
Feature
Description:
Test program for the Flexible PHDF5 feature.
Platforms tested:
Tested on modi4 before but the feature is currenly disabled in
configure. Checking this in for future work.
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.
Bug Fix
Description:
Metadata cache in parallel I/O can cause hangs in applications which
perform independent I/O on chunked datasets, because the metadata cache
can attempt to flush out dirty metadata from only a single process, instead
of collectively from all processes.
Solution:
Pass a dataset transfer property list down from every API function which
could possibly trigger metadata I/O.
Then, split the metadata cache into two sets of entries to allow dirty
metadata to be set aside when a hash table collision occurs during
independent I/O.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir) serial & parallel
Misc. update:
Updated release_docs/RELEASE
bug fix
Description:
Added a barrier to ensure all processes have finished using
the file before cleaning it away.
Added H5close() to ensure all HDF5 stuff are closed before
calling MPI_Finalize.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}? Yes
New feature
Description:
Add support for scalar dataspaces in parallel I/O.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
Also, FreeBSD 4.7 (sleipnir) serial & parallel
Misc. update:
Update release_docs/RELEASE for bug fixes, new features, etc.
Testing fix.
Description:
Correctly detect when one of the parallel tests fails and stop the make
from proceeding.
Platforms tested:
modi4 (parallel), sleipnir (parallel)
API name change
Description:
Change all "space time" references to "alloc time", including API functions
and macro definitions, etc.
Platforms tested:
FreeBSD 4.6 (sleipnir) w/C++
Solaris 2.7 (arabica) w/FORTRAN
IRIX64 6.5 (modi4) w/parallel & FORTRAN
Bug fix
Description:
script did not work for SP system.
Solution:
added "eval" command to launch the mpi execution. This works fine
for SP and is basically a no-op for non-batch systems like workstations.
Also got rid of the wrongle implemented TESTING message since the
result was not printed and the tests output mess up the format already.
Platforms tested:
SP (snow). Did not test more since it has been tested out fine
in the v1.4 checkin.
Additional test
Description:
Add in a fill-value to one of the tests, to make certain that they are
handled correctly.
Platforms tested:
FreeBSD 4.6 (sleipnir) w/serial & parallel
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.
