* [svn-r12358] Purpose:Albert Cheng2006-05-191-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix. Description: The ${TR}, though avoid the error, is inconvenient. It is needed because configure.in use the char range in the style of 'a-z'. The other style of '[a-z]' is more commonly accepted by all tr but autoconf tends to strip away [], making the syntax rather clumsy. Solution: Learned from autoconf that it avoids the use of character range by just spell all the letters out. Changed our tr commands to use those variables defined by autoconf. Also removed the definition of ${TR} since it will cause inconsistancy when autoconf also use plain 'tr' in its generated code. The Makefile.in are changed because the elimination of ${TR} from configure triggered its removal from all Makefil.in. That is okay because ${TR} is not used at all in Makefile. Platforms tested: h5committested. (sol failed to connected). also tested in shanti using both /usr/ucb/tr and /bin/tr (the bad one before.) Misc. update: Updated both INSTALL and RELEASE files.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix Description: Fix two test bugs: 1) Unitialized variable bug in test of H5C_get_entry_status() (in test/cache.c) 2) Incorrect initialization of constant in t_cache when running with MPE. (in testpar/t_cache.c) Solution: 1) Don't test uninitialize variable. 2) Correct initialzation of constant in MPE case. Platforms tested: Tested on Heping and Copper. Misc. update:
* [svn-r12316] Purpose:Quincey Koziol2006-04-291-12/+14
| | | | | | | | | | | | | | | Code cleanup/feature twist Description: Adjust recent H5AC routines to take H5F_t pointers instead of H5C_t pointers, to match the rest of the H5AC routines. This change propagated into a few of the tests, which also had some compiler warnings cleaned up... Platforms tested: FreeBSD 4.11 (sleipnir) w/parallel Linux 2.4/64 (mir) w/C++ & FORTRAN
* [svn-r12311] Purpose:John Mainzer2006-04-281-132/+1046
| | | | | | | | | | | | | | | | | | | | | | | | | Add pinned entry capability to cache. Description: For frequently accessed cache entries, the protect/unprotect overhead is sometimes a bottleneck. Solution: Allow entries to be pinned in the cache. Pinned entries can't be evicted, but can be flushed or modified. Platforms tested: h5committested -- minus one small typo in test/cache.c whose fix was tested on copper and heping only. Misc. update:
* [svn-r12295] Purpose:James Laird2006-04-211-3/+3
| | | | | | | | | | | | | | | | | | | Several bug fixes Description: Added config file for Cray X1 (previous file was misnamed) Simplified some code in hyperslab.c test that seemed to have been confusing compiler on Cray X1. Fixed typo in config/commence.am Cleaned up hl/src/Makefile.am Solution: All four fixes should be straightforward. The failure on Cray was very difficult to debug, but involved arithmetic errors. This change seems to fix it. Platforms tested: heping, copper, sol, some Cray X1 (more testing when system comes back up)

* [svn-r12229] Purpose:Pedro Vicente Nunes2006-04-122-2/+5
| | | | | | | | | | | | | | | | | | | | | new feature Description: 1) separated the HL library into "public" and "private" header files, with the same caracteristics as the basic library 2) added the public headers to hdf5.h (with a conditional include macro, defined in configure.in) 3) added the path to HL in all Makefile.am 's , because of the inclusion in hdf5.h Solution: Platforms tested: linux 32, 64 AIX solaris with fortran and c++ (one packet table example fails) Misc. update:
* [svn-r12227] Purpose:Albert Cheng2006-04-121-5/+5
| | | | | | | | | | | | | | | | | bug fix. Description: The MPE_Stop_log did not work in copper. It spewed out MPE errors and ended in infinite looping. Solution: Changed to a smaller test size to avoid generating huge MPE log files when MPE is configured in. Platforms tested: Copper (mpe) Misc. update:
* [svn-r12224] Purpose:Albert Cheng2006-04-111-0/+5
| | | | | | | | | | | | | | | | Bug fix. Description: When MPE is used, the test generates huge Clog files in /tmp that could fill up the disk (like in Copper.) Solution: Turned off MPE logging. Platforms tested: heping (pp) and copper(pp) Misc. update:
* [svn-r12174] Purpose:MuQun Yang2006-03-293-9/+484
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding parallel tests for optional collective chunk APIs Description: Three new APIs "H5Pset_dxpl_mpio_chunk_opt_ratio H5Pset_dxpl_mpio_chunk_opt_num H5Pset_dxpl_mpio_chunk_opt" for optional optimization choices from users have been added to the libraries. This check-in adds six tests to verify the funcationality and correctedness of these APIs. These tests need to be verified with 3 or more processors and with MPI-IO driver only. Solution: Using H5Pinsert, H5Pget, H5Pset to verify that the library indeed goes into the branch we hope for. Using H5_HAVE_INSTRUMENT macro to isolate these changes so that it won't affect or be misused by the application. Platforms tested: h5committest(shanti still refused to be connected) Parallel tests on heping somehow are skipped. Manually testing at heping. Have checked 1,2,3,4,5 processes. Misc. update:
* [svn-r12149] Purpose:James Laird2006-03-231-7/+1
| | | | | | | | | | | | | | | | Bug fix Description: Previous checkin did a bad thing; 'make clean' failed in example directories. Solution: Fixed commence.am so that examples no longer break, and fixed a mistake in conclude.am. Platforms tested: heping (minor makefile change) Misc. update:
* [svn-r12148] Purpose:MuQun Yang2006-03-232-1/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add tests for optional APIs to support collective chunk IO Description: In order to test whether library picks up the user's options, The number of chunks need to be varied for different processes, Selection of the number of processes selected in one chunk also need to be varied. Solution: Create two cases, 1. Each chunk only selected by one unique process, this case library should use independent for collective call. 2. One-third of the processes occupies the top half of the whole domain, The rest of the processes occupies the lower half of the domain. The total number of chunk is a fixed number 8. Platforms tested: Linux 2.4 with mpich 1.2.6(only) Since I only checked in the code that handles the selection, haven't added any new tests yet. So it won't affect any platforms. Misc. update:
* [svn-r12143] Purpose:James Laird2006-03-231-0/+4
| | | | | | | | | | | | | | Bug fix Description: make check-clean didn't clean results of example tests Solution: Fixed Makefiles so that check-clean recurses into example directories. Also a little Makefile cleanup. Platforms tested: mir, modi4, heping, copper
* [svn-r12142] Purpose:MuQun Yang2006-03-233-69/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | change the array size of collective chunking features of parallel tests. Description: Previously array size for collective optimization tests including cchunk1, cchunk2, cchunk3, cchunk4, ccontw, ccontr, cschunkw, cschunkr, ccchunkw, ccchunkr are fixed, They are only valid for some good number of processors(1,2,3,4,6,8,12,16,24,32,48 etc). Recently there are more requests for parallel tests to be valid on some odd number of processes such as 5,7,11,13 etc. Solution: I change the array size to be dynamic rather than static. Now the fastest change array size is a function of mpi_size. dim2 = constant *mpi_size. After some tunings, theoretically the above tests should be valid for any number of processors. However, other parallel tests still need to be tuned. To verify the correctness of these tests, using mpirun -np 5 ./testphdf5 -b cchunk1 at heping. Platforms tested: h5committest(shanti is refused to be connected) at heping, 5 and 7 processes are used to verify the correctness. Misc. update:
* [svn-r12044] Purpose:MuQun Yang2006-03-092-26/+236
| | | | | | | | | | | | | | | Add new tests Description: Collective IO doesn't work for some platforms/mpio packages when more than one process has no contributions to IO. Solution: 1. Add a collective IO test to verify the correctness of the library when more than one process has no contributions to IO. 2. Add the similar MPI-IO test in t_mpi to help us maintain in more platforms. Platforms tested: heping, mir, copper Misc. update:
* [svn-r11992] Purpose:Albert Cheng2006-03-012-5/+4
| | | | | | | | | | | | Improvement. Description: The t_cache takes a long long time to run and it tests HDF5 calls. Move it to the back and let more basic tests to run first so that basic features are tested first. Platforms tested: Tested in heping with pp.
* [svn-r11953] Purpose:MuQun Yang2006-02-171-2/+0
| | | | | | | | | | | | | | code cleanup Description: remove two printf lines accidently added for debugging at NCSA cobalt. Solution: Platforms tested: No need to test. Misc. update:
* [svn-r11951] Purpose:MuQun Yang2006-02-163-4/+71
| | | | | | | | | | | | | | | | Enhance collective chunk IO supports Description: Add a new test to check the correctness of the HDF5 library behavior for collective IO mode when one process doesn't have any contribution for IO. Solution: Platforms tested: IBM AIX 5.2(copper) Linux (heping) mpich-1.2.6 Misc. update:
* [svn-r11915] Purpose:John Mainzer2006-01-311-7/+19
| | | | | | | | | | | | | | | | | | | Attempt to ensure that the parallel cache test runs at a reasonable speed with large numbers of processors. Description: In some cases, the number of random locks and unlocks was a multiple of the MPI rank. Solution: Use rank % 4 instead of simply rank. Platforms tested: copper Misc. update:
* [svn-r11904] Purpose:John Mainzer2006-01-291-0/+3487
| | | | | | | | | | | | | | | | | | | | | Add a file that I forgot in my last checkin. Description: t_cache.c is the source file for the new parallel metadata cache test. Solution: See above. Platforms tested: h5committested before the last checkin. Will run another h5committest shortly, but it shouldn't be necessary as there are no new changes. Misc. update:
* [svn-r11897] Purpose:John Mainzer2006-01-272-9/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Add parallel test for metadata cache 2) Split serial test for metadata cache into two parts 3) Fix bug in which cache was flushed needlessly when the cache wasn't full. 4) Performance improvements 5) Update API for parallel cache coherency bug fix. Description: See above. Solution: See above. Platforms tested: h5committest Misc. update:
* [svn-r11866] Purpose:Albert Cheng2006-01-061-6/+2
| | | | | | | | | | | | | | | | | | | | bug fix 504 Description: testpar/t_mpi would hang if $HDF5_NOCLEANUP is set. E.g., % env HDF5_NOCLEANUP=yes mpirun -np 3 ./t_mpi This happened because the environment variables are not exported to all mpi processes by the mpirun command. So, some attempted to do cleanup while others don't and some hang waiting for others to act. Solution: Instead individual program checking getenv, they all just called h5_cleanup no matter. h5_cleanup now uses getenv_all to check the $HDF5_NOCLEANUP if it is in parallel mode. Platforms tested: h5committested, tested pp in heping too.
* [svn-r11798] Purpose:Albert Cheng2005-12-161-0/+17
| | | | | | | | | | | Feature. Description: Modified it so that it can be compiled outside of HDF5 library as a standalone program. e.g., mpicc -DSTANDALONE prog.c. Platforms tested: Tested in Red storm and heping.
* [svn-r11788] Purpose:Albert Cheng2005-12-121-2/+5
| | | | | | | | | | | | | | | | | | Patch. Description: Copper would fail with a message of 0032-113 Out of memory in routine unknown, task 0 when run with 3 processes and size 1MB in MPI-IO tests. It seems to be a copper MPIO error. Solution: Reduced the upper bound of default write size to 1/2MB (but tests only go to 1/4MB) for now, pending permenant fix from Copper. Platforms tested: Copper.
* [svn-r11786] Purpose:Leon Arber2005-12-111-18/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Minor bug fixes. Description: 1. Changed free() calls to HDfree() 2. Corrected behavior of -m command-line parameter 3. Changed return value to always return 0. Solution: 2. The -m flag tells the test to run only the MPI IO tests. However, it would incorrectly make the test run both the MPI and POSIX tests (same as the default behavior). 3. This test is known to fail on many platforms, and, even on those platforms where it usually passes, it is known to suffer transient failures (especially with small test file sizes). It's outcome is also very dependent on the filesystem on which the testfile is created. Corrected the program to always return success, so that it doesn't interfere with the daily tests. The motivation for this is that this test has nothing to do with the HDF library and is an auxiliary test. Failures in t_posix_complaint do not necessarily mean that parallel HDF will fail, but simply indicate something to look into, especially on new platforms. This is now an "output only" test, and any errors will be only be visible in the output. Platforms tested: copper (all of these were minor changes) Misc. update:
* [svn-r11783] Purpose:Albert Cheng2005-12-111-16/+32
| | | | | | | | | | | | | | | | bug fix. Description: Fixed the segmentation fault errors in modi4, copper and tg-login. It was due to the misuse of trying to realloc a pointer returned by getenv_all. (not supposed to.) Also rearranged the code so that option is checked first, then check with environment variable, then use default setup. This saves the need to do realloc at all. Platforms tested: Heping, modi4, shanti, copper (copper showed a different error now.)
* [svn-r11778] Purpose:Leon Arber2005-12-081-7/+9
| | | | | | | | | | | | | | | | | Bug fix. Description: For some strange reason, getopt() does not appear to be defined in unistd.h on colonelk when the source is compiled with -D_POSIX_SOURCE. Solution: Inserted some extern's for the missing variables to make the compiler happy. Platforms tested: colonelk, copper Misc. update:
* [svn-r11777] Purpose:Leon Arber2005-12-081-6/+23
| | | | | | | | | | | | | | | | | | | | Feature Description: Added blurb about future todo's for this test. Added support for HDF5_PARAPREFIX to determine the directory where the test file is stored. Solution: Used getenv_all to get the value of HDF5_PARAPREFIX. Note that, if a command-line parameter is passed to the program to specify a path, it will override the value of HDF5_PARAPREFIX. Platforms tested: copper, colonelk Misc. update:
* [svn-r11776] Purpose:Leon Arber2005-12-083-35/+41
| | | | | | | | | | | | | | Added t_posix_compliant to the rest of the build and patched up minor compile bugs/warnings encountered on other platforms. Description: It seems that <getopt.h> needs to be included to get the file to build, even though the man page seems to indicate that <unistd.h> should be sufficient. Solution: Platforms tested: copper, colonelk, sol
* [svn-r11772] Purpose:Leon Arber2005-12-081-0/+847
| | | | | | | | | | | | | | | | | | | Feature Description: Added posix compliance tests. Solution: These tests do increasingly complicated sets of writes followed by reads. POSIX standards say that any read that can be proven to occur after a write must include the data in that write. These tests attempt to verify whether the underlying filesystem and i/o layer provide such guarantees. Platforms tested: copper, colonelk, red storm Misc. update:
* [svn-r11741] Purpose:James Laird2005-11-181-6/+16
| | | | | | | | | | | | | | | | | Bug fix Description: Fortran type generation was broken in two ways. Fixed both. Solution: Firstly, there were a couple of path problems. Fixed a typo and specified the full path of a file. Secondly, the dependencies weren't right when building with HDF5-specific commands (make lib, make check-s, etc.). Tweaked dependencies to fix the problem. Platforms tested: mir, modi4, sleipnir
* [svn-r11738] Purpose:James Laird2005-11-181-0/+4
| | | | | | | | | | | | | | | | | | | Configure feature Description: Added 'make trace' target. Solution: Added tracing to 1.7. This was done automatically in 1.6, but left out of 1.7 until now (oops!). Tracing in 1.7 only happens manually, when the user types 'make trace.' Tracing automatically requires more framework than it's worth. I also fixed a couple of tracing bugs and ran trace. Platforms tested: mir, sleipnir, modi4 Misc. update:
* [svn-r11737] Purpose:James Laird2005-11-171-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Bug fix Description: Before this checkin, 'gmake check-s' would fail if there was a file in the current directory named 'check-s'. This is fixed under gmake (not sure how to fix for other makes). Solution: check, progs, install, etc. are what gmake calls "phony" targets, which means that no file should be created. These targets can be specified by a line of the form .PHONY: check progs install ... Automake adds this line for targets it knows about, but HDF5 has a lot of custom rules. This checkin adds a .PHONY line for those rules. I believe that only gmake recognizes the .PHONY line (at least, pmake doesn't seem to), but a partial solution is better than none. This error should occur very rarely anyway (the user has to manually create files with names like 'build-check-s' or '_test'). Platforms tested: mir, sleipnir, modi4
* [svn-r11646] Purpose:James Laird2005-10-311-4/+14
| | | | | | | | | | | | | | | | | | Bug fix/feature Description: Added support for -shlib in h5fc and h5c++. Made check-install use -shlib when only shared libraries have been installed. Solution: h5fc and h5c++ didn't recognize -shlib. Stole code from h5cc to link against shared libraries. When static libraries are disabled, the examples Makefiles will automatically use the -shlib option to link against shared libraries. Thus, --disable-static and make check-install should work together. Platforms tested: heping(disable-static, enable-static, fortran, c++), modi4 (disable-static, fortran, c++, parallel, enable-static)
* [svn-r11612] Purpose:James Laird2005-10-271-1/+1
| | | | | | | | | | | | | Bug fix Description: Failed parallel tests now cause make to exit with an error. Solution: Edited config/conclude.am to throw an error if parallel test programs fail. Platforms tested: heping, modi4
* [svn-r11602] Purpose:James Laird2005-10-241-3/+0
| | | | | | | | | | | | Bug fix Description: Removed detection of pdb from configure.in as a corollary to removal of pdb2hdf5 tool. Platforms tested: mir, modi4
* [svn-r11576] Purpose:MuQun Yang2005-10-181-152/+261
| | | | | | | | | | | | | | | | | | Adding comments and code clean-up for code that tests collective irregular selection Description: For better maintenance in the future, Add comments to list the number for (start,count,block,stride) for irregular selection for effective testing collective chunk IO feature development in the future. Solution: Platforms tested: Linux 2.4(heping), mostly comments, no need to test on other platforms. Misc. update:
* [svn-r11573] Purpose:James Laird2005-10-171-0/+1
| | | | | | | | | | | | | | | | | | | | Bug fix Description: Changed configure.in to use an environment variable TR to set the path to the tr utility. Solution: There are two kind of tr on Solaris with slightly different syntax. HDF5's configure relies on the "standard" tr. Traditionally, HDF5ers have needed to make sure that the "right" tr was found before the wrong one in their path; now they can use an environment variable. Platforms tested: mir, shanti, sol Misc. update: Forgot to update release notes. Off to do that now.
* [svn-r11572] Purpose:MuQun Yang2005-10-172-208/+294
| | | | | | | | | | | | | | | Code clean-up for collective regular chunk IO tests. Description: Add descriptions for each tests for future maintenance. Solution: Platforms tested: Mostly comments, No need to use h5committest. heping(linux 2.4) Misc. update:
* [svn-r11566] Purpose:James Laird2005-10-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Makefile bug fix Description: Previously, automake didn't output rules to build perform/mpi-perf or the test/gen_* programs. Now these can be built by typing 'make mpi-perf' (or 'make foo') or by configuring with --enable-build-all. Solution: Automake doesn't like having rules for programs it doesn't build. Tricked it by having these programs built "sometimes"--whenever the user enables --build-all. This should be used mostly for testing and to ensure that these helper programs compile. ***IMPORTANT*** These programs do *not* currently compile. When --enable-build-all is used (not the default), gen_new_fill fails because it uses an old API. This is an existing "bug" that has simply been exposed by this checkin. Platforms tested: sleipnir, modi4, sol Misc. update:
* [svn-r11483] Purpose:Leon Arber2005-09-291-7/+7
| | | | | | | | | | | | | | | | bug fix. Description: The complex derived datatype test assumed that the fill value would be 0. This is not the case on all systems. Solution: Modified the test to check against a known value in the outbuf array, instead of the fill value. Platforms tested: heping and MCR. Misc. update:
* [svn-r11481] Purpose:Leon Arber2005-09-291-1/+1
| | | | | | | | | | | | | | | bug fix. Description: Fixed typo in a comment. The word "file" was supposed to be "fill." The explanation of how the complex derived datatype test works is much clearer now. Solution: Platforms tested: minor change. Misc. update:
* [svn-r11478] Purpose:Albert Cheng2005-09-291-8/+7
| | | | | | | | | | | | | | | | bug fix. Description: When a parallel test script test fails, make would continue because the way it was setup inside a for loop. Fixed it by issuing an exit 1 inside the loop. There was also a typo error in the newer command comparision that it must be $${chkname} in order to be valid. Also, the test script itself was not checked in the newer lists. All fixed. Platforms tested: h5committested and also hand tested in heping pp mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Repair synchronization bug in the metadata cache in PHDF5 Also repair numerous other bugs that surfaced in testing the bug fix. Description: While operations modifying metadata must be collective, we allow independant reads. This allows metadata caches on different processes to adjust to different sizes, and to place the entries on their dirty lists in different orders. Since only process 0 actually writes metadata to disk (all other processes thought they did, but the writes were discarded on the theory that they had to be collective), this made it possible for another process to modify metadata, flush it, and then read it back in in its original form (pre-modification) form. The possibilities for file corruption should be obvious. Solution: Make the policy that only process 0 can write to file explicit, and visible to the metadata caches. Thus only process 0 may flush dirty entries -- all other caches must retain dirty entries until they are informed by process 0 that the entries are clean. Synchronization is handled by counting the bytes of dirty cache entries created, and then synching up between the caches whenever the sum exceeds an (eventually user specified) limit. Dirty metadata creation is consistent across all processes because all operations modifying metadata must be collective. This change uncovered may bugs which are repaired in this checkin. It also required modification of H5HL and H5O to allocate file space on insertion rather than on flush from cache. Platforms tested: H5committest, heping(parallel & serial) Misc. update:
* [svn-r11459] Purpose:MuQun Yang2005-09-221-2/+3
| | | | | | | | | | | | | | | | | | A bug fix Description: MPI_Status_IGNORE is treated as a NULL pointer for mpich 1.2.4 or similar MPI packages. It caused segmentation fault for MPI derived datatype test. Solution: Define MPI_STATUS status, and pass &status into MPI_File_read and MPI_File_write. Platforms tested: too trivial to test. Misc. update:
* [svn-r11458] Purpose:Albert Cheng2005-09-221-13/+30
| | | | | | | | | | | | | | | | | | Improvement. Description: The test may hang if there are system failures that some processors are not working. Solution: Added the ALARM calls to limit all tests be done with the default alarm time. So, even if a process is hanging, the ALARM signal would terminate the process. Platforms tested: tg-login2 of NCSA. Misc. update:

| | | | | | | | | | | | | | | | | New feature. Description: Added the time command to the make check target to report time usage of the execute of each test and test scripts. This gives us some idea how long each test takes and some vague idea it is compute bound or not. powerpc-ibm-aix5.x: Change $RUNPARALLEL default setting to allow it being invoked by the time command. Platforms tested: h5committested.
