* Subfiling VFD (#1883)jhendersonHDF2022-07-221-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Added support for vector I/O calls to the VFD layer, and associated test code. Note that this includes the optimization to allow shortened sizes and types arrays to allow more space efficient representations of vectors in which all entries are of the same size and/or type. See the Selection I/o RFC for further details. Tested serial and parallel, debug and production on Charis. serial and parallel debug only on Jelly. * ran code formatter quick serial build and test on jelly * Add H5FD_read_selection() and H5FD_write_selection(). Currently only translate to scalar calls. Fix const buf in H5FD_write_vector(). * Format source * Fix comments * Add selection I/O to chunk code, used when: not using chunk cache, no datatype conversion, no I/O filters, no page buffer, not using collective I/O. Requires global variable H5_use_selection_io_g be set to TRUE. Implemented selection to vector I/O transaltion at the file driver layer. * Fix formatting unrelated to previous change to stop github from complaining. * Add full API support for selection I/O. Add tests for this. * Implement selection I/O for contiguous datasets. Fix bug in selection I/O translation. Add const qualifiers to some internal selection I/O routines to maintain const-correctness while avoiding memcpys. * Added vector read / write support to the MPIO VFD, with associated test code (see testpar/t_vfd.c). Note that this implementation does NOT support vector entries of size greater than 2 GB. This must be repaired before release, but it should be good enough for correctness testing. As MPIO requires vector I/O requests to be sorted in increasing address order, also added a vector sort utility in H5FDint.c This function is tested in passing by the MPIO vector I/O extension. In passing, repaired a bug in size / type vector extension management in H5FD_read/write_vector() Tested parallel debug and production on charis and Jelly. * Ran source code formatter * Add support for independent parallel I/O with selection I/O. Add HDF5_USE_SELECTION_IO env var to control selection I/O (default off). * Implement parallel collective support for selection I/O. * Fix comments and run formatter. * Update selection IO branch with develop (#1215) Merged branch 'develop' into selection_io * Sync with develop (#1262) Updated the branch with develop changes. * Implement big I/O support for vector I/O requests in the MPIO file driver. * Free arrays in H5FD__mpio_read/write_vector() as soon as they're not needed, to cut down on memory usage during I/O. * Address comments from code review. Fix const warnings with H5S_SEL_ITER_INIT(). * Committing clang-format changes * Feature/subfiling (#1464) * Initial checkin of merged sub-filing VFD. Passes regression tests (debug/shared/paralle) on Jelly. However, bugs and many compiler warnings remain -- not suitable for merge to develop. * Minor mods to src/H5FDsubfile_mpi.c to address errors reported by autogen.sh * Code formatting run -- no test * Merged my subfiling code fixes into the new selection_io_branch * Forgot to add the FindMERCURY.cmake file. This will probably disappear soon * attempting to make a more reliable subfile file open which doesn't return errors. For some unknown reason, the regular posix open will occasionally fail to create a subfile. Some better error handling for file close has been added. * added NULL option for H5FD_subfiling_config_t in H5Pset_fapl_subfiling (#1034) * NULL option automatically stacks IOC VFD for subfiling and returns a valid fapl. * added doxygen subfiling APIs * Various fixes which allow the IOR benchmark to run correctly * Lots of updates including the packaging up of the mercury_util source files to enable easier builds for our Benchmarking * Interim checkin of selection_io_with_subfiling_vfd branch Moddified testpar/t_vfd.c to test the subfiling vfd with default configuration. Must update this code to run with a variety of configurations -- most particularly multiple IO concentrators, and stripe depth small enough to test the other IO concentrators. testpar/t_vfd.c exposed a large number of race condidtions -- symtoms included: 1) Crashes (usually seg faults) 2) Heap corruption 3) Stack corruption 4) Double frees of heap space 5) Hangs 6) Out of order execution of I/O requests / violations of POSIX semantics 7) Swapped write requests Items 1 - 4 turned out to be primarily caused by file close issues -- specifically, the main I/O concentrator thread and its pool of worker threads were not being shut down properly on file close. Addressing this issue in combination with some other minor fixes seems to have addressed these issues. Items 5 & 6 appear to have been caused by issue of I/O requests to the thread pool in an order that did not maintain POSIX semantics. A rewrite of the I/O request dispatch code appears to have solved these issues. Item 7 seems to have been caused by multiple write requests from a given rank being read by the wrong worker thread. Code to issue "unique" tags for each write request via the ACK message appears to have cleaned this up. Note that the code is still in poor condtition. A partial list of known defects includes: a) Race condiditon on file close that allows superblock writes to arrive at the I/O concentrator after it has been shutdown. This defect is most evident when testpar/t_subfiling_vfd is run with 8 ranks. b) No error reporting from I/O concentrators -- must design and implement this. For now, mostly just asserts, which suggests that it should be run in debug mode. c) Much commented out and/or un-used code. d) Code orgnaization e) Build system with bits of Mercury is awkward -- think of shifting to pthreads with our own thread pool code. f) Need to add native support for vector and selection I/O to the subfiling VFD. g) Need to review, and posibly rework configuration code. h) Need to store subfile configuration data in a superblock extension message, and add code to use this data on file open. i) Test code is inadequate -- expect more issues as it is extended. In particular, there is no unit test code for the I/O request dispatch code. While I think it is correct at present, we need test code to verify this. Similarly, we need to test with multiple I/O concentrators and much smaller stripe depth. My actual code changes were limited to: src/H5FDioc.c src/H5FDioc_threads.c src/H5FDsubfile_int.c src/H5FDsubfile_mpi.c src/H5FDsubfiling.c src/H5FDsubfiling.h src/H5FDsubfiling_priv.h testpar/t_subfiling_vfd.c testpar/t_vfd.c I'm not sure what is going on with the deletions in src/mercury/src/util. Tested parallel/debug on Charis and Jelly * subfiling with selection IO (#1219) Merged branch 'selection_io' into subfiling branch. * Subfile name fixes (#1250) * fixed subfiling naming convention, and added leading zero to rank names. * Merge branch 'selection_io' into selection_io_with_subfiling_vfd (#1265) * Added script to join subfiles into a single HDF5 file (#1350) * Modified H5FD__subfiling_query() to report that the sub-filing VFD supports MPI This exposed issues with truncate and get EOF in the sub-filing VFD. I believe I have addressed these issues (get EOF not as fully tested as it should be), howeer, it exposed race conditions resulting in hangs. As of this writing, I have not been able to chase these down. Note that the tests that expose these race conditions are in testpar/t_subfiling_vfd.c, and are currently skipped. Unskip these tests to reproduce the race conditions. tested (to the extent possible) debug/parallel on charis and jelly. * Committing clang-format changes * fixed H5MM_free Co-authored-by: mainzer

* [svn-r19941] Purpose:Albert Cheng2011-01-121-3/+2
| | | | | | | | | | | | | | | | | | | | | | | Moved the two shape same tests from testphdf5 to a separated executables, named t_shapesame. The shape same tests runs too long for testphdf5. In a separated executalbe, it will be easier to separate any errors in testphdf5 sub-tests from the shape same tests. t_shapesame.c: Contains the shape same tests (cloned from t_rank_projection.c) plus a duplicate of "testphdf5.c" for now. After verifying it is correct, more cleanup is needed. testphdf5.c: Removed the two shape same tests (chsssdrpio & cbhsssdrpio). Makefile.am: Makefile.in: Added t_shapesame as a new test executable. Removed t_rank_projections.c from part of testphdf5. testph5.sh.in: Temporary added the "t_shapesame -p" test for testing shape same tests with MPIO-Posix VFD. Tested: h5committested, plus serial jam.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bring "shape same" changes from LBL branch to trunk. These changes allow shapes that are the same, but projected into dataspaces with different ranks to be detected correctly, and also contains code to project a dataspace into greater/lesser number of dimensions, so the I/O can proceed in a faster way. These changes also contain several bug fixes and _lots_ of code cleanups to the MPI datatype creation code. Many other misc. code cleanup are included as well...

* [svn-r12431] Purpose:James Laird2006-06-211-1/+1
| | | | | | | | | | | | | | Configuration feature Description: 'make install' now tests both static and shared libraries if both are installed. Solution: Previously, shared libraries were only tested when static libraries were not installed. Also cleaned up line in commence.am that was including HL library in all Makefiles. Platforms tested: mir (Makefile change only)

* [svn-r12229] Purpose:Pedro Vicente Nunes2006-04-121-1/+1
| | | | | | | | | | | | | | | | | | | | | 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-r11776] Purpose:Leon Arber2005-12-081-1/+1
| | | | | | | | | | | | | | 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-r11411] Purpose:James Laird2005-09-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix Description: Building with --disable-static seems to have been broken on several platforms. Fixed this. Configure will now disable shared libraries automatically when using pgf90 or when building on Cygwin. Solution: To avoid errors when using shared libraries with pgf90 (which I had not realized were compiler-specific), I had manually set convenience libraries to use the -static linking flag. Apparently, this is not necessary, and caused these libraries to be created as empty archives when --disable-static was used. Also, some libraries were including other libraries, which was not necessary. I also fixed code in configure.in to correctly detect whether shared or static libraries are enabled, and moved code that disables shared libraries to before libtool is created (rather than editing libtool after the fact). Despite repeated warnings that only one shared library can be linked at a time, I have yet to have shared libraries break the linking of tests on any system. We'll see if the Daily Tests turn up anything. Platforms tested: mir (fortran, C++), sleipnir (C++), modi4 (fortran, C++, parallel), sol (fortran, C++), cygwin
* [svn-r11323] Purpose:Albert Cheng2005-08-311-2/+0
| | | | | | | | | | | | | | | | tidy up. Description: MPE option created *.clog file whenever it is executed in MPI. The cleanup of *.clog files were done in individual Makefile.in. Often, it is forgotten. Solution: Moved the cleaning of *.clog files to CHECK_CLEANFILES in commence.am so that it is applied whenever check-clean is called. Platforms tested: heping pp using MPE.
* [svn-r11312] Purpose:Albert Cheng2005-08-301-1/+1
| | | | | | | | | | | | | | | | | | Bug #281 Description: A dataset created in serial mode with H5D_ALLOC_TIME_INCR allocation setting was not extendible, either explicitly by H5Dextend or implicitly by writing to unallocated chunks. This was because parallel mode expects the allocation mode be H5D_ALLOC_TIME_INCR only. Solution: Modified library to allocate more space when needed or directed if the file is opened by parallel mode, independent of what the dataset allocation mode is. Platforms tested: Heping pp.
* [svn-r11214] Purpose:Albert Cheng2005-08-081-1/+1
| | | | | | | | bug fix Description: Previous commit contained an extra bin (t_chunk_alloc) that is not ready yet. It was a mistake. Removed it.
* [svn-r11208] Purpose:Albert Cheng2005-08-081-1/+1
| | | | | | | | | | | | | | | | | | | Bug fix and code minor cleanup. Description: The attempt to redirect stderr together to the log files were done in the wrong order such that stderr output goes to where stdout WAS. Fixed that. Code minor cleanup--use shell variables to hold the name of the log file and the test instead of generating them repeatedly. This makes easier code reading, less crowded and avoid typos. Only conclude.in is changed. The Makefile.in changes are all derived from automake. Platforms tested: h5committested.
* [svn-r11185] Purpose:James Laird2005-08-021-1/+2
| | | | | | | | | | | | | | | Makefile feature Description: 'make check-clean' now cleans *.h5 files created by tests as well as .log and .chkexe files. Solution: check-clean is now a separate target in its own right, which cleans less than mostlyclean (check-clean < mostlyclean < clean < distclean). Platforms tested: mir, heping, modi4 (serial and parallel)
* [svn-r11008] Purpose:James Laird2005-06-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | Feature: tests now use parallel make and only run once Description: When make is invoked in parallel (using the -j option), several tests will now be run simultaneously. This should speed up testing on a number of systems. When a test passes, it creates a foo.chkexe or foo.chksh file, which prevents the test from running again unless the test or library changes. Solution: Most of the changes live in config/conclude.am. Added *.chkexe and *.chksh files to the list of files to be cleaned at "make mostlyclean" time. Parallel tests still run one at a time, but use the same make instructions as serial tests. Platforms tested: mir, eirene, sleipnir, pommier, copper, modi4 (some errors occurred, probably due to the test being run before updating hdf5. Will re-run tests after checkin.)
* [svn-r10840] Purpose:James Laird2005-06-021-1/+1
| | | | | | | | | | | Added check-s and check-p targets. Description: Added check-s and check-p targets to 1.7 branch to match changes to 1.6 branch. Now parallel and serial tests can be run separately. Platforms tested: mir, modi4, copper
