| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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

* VFD ctl feature (#981)jhendersonHDF2021-09-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Added "ctl" callback to the VFD interface, and the associated H5FDctl() and H5FD_ctl() calls. Modified the MPIO VFD accordingly -- specifically: Added ctl() call with op-code support to expose rank, size, and communicator. Modified H5FD_mpi_get_rank(), H5FD_mpi_get_size(), and H5FD_mpi_get_comm() to use the new ctl() callback. In passing removed the const qualifier from the file parameter of these functions, as the file parameter of the ctl callback is not const. Deleted the old H5FD__mpio_mpi_rank(), H5FD__mpio_mpi_size(), and H5FD__mpio_communicator() calls from the MPIO VFD. Deleted H5FD_class_mpi_t from H5FDprivate.h, and modified the MPIO VFD accordingly. Note that all VFDs now use H5FD_class_t, with no special class for VFDs that that support MPI. Some minor touch ups to the Neil's selection I/O mods in passing. Tested serial and parallel, debug and production on charis and jelly. * Reserve a range of VFD "ctl" opcodes for library and experimental usage * Add "ctl" callbacks to passthrough VFDs * Add RELEASE.txt entry for "ctl" callback * Use H5FDopen with H5F_ACC_RDWR flag instead of H5F_ACC_TRUNC in vfd test * Remove handling of passthrough "ctl" flag from multi VFD * Move logic for testing H5FD_CTL__TEST_OPCODE into a testing VFD Revise description of "ctl" callback in RELEASE.txt Remove unused H5FD_CTL__NUM_OPCODES definition Fix some warnings in multi VFD Co-authored-by: mainzer <mainzer#hdfgroup.org>

Also clean up many compiler warnings. * Committing clang-format changes * Merge from develop * Fix mis-placed assert * Remove commented-out code * Re-add macro for unsetenv on Windows (I think it accidentally was merged out) * Strengthen sanity check from error report to assertion * Committing clang-format changes * Add units to the comments for a few fields * Switch 'get execution time' operation for async request tokens to be an optional operation and query if connector supports operation before retrieving it. * Committing clang-format changes * Remove H5ESget_time_estimate * Committing clang-format changes * Create developer header for datatype routines and move type conversion register/unregister routines there. * Simplify internal H5VL_setup_name_args and H5VL_setup_idx_args routines * Add H5VLlink_optional_op, allowing dynamicly registered optional operations for the link VOL subclass, also added H5VL_loc_params argument to the link 'optional' callback to allow them to work correctly. * Run bin/format_source on current code * Add H5VLobject_optional_op, allowing dynamicly registered optional operations for the object VOL subclass, also added H5VL_loc_params argument to the object 'optional' callback to allow them to work correctly. * Run bin/format_source on current code * Committing clang-format changes * Revert "Switch 'get execution time' operation for async request tokens to be an optional operation and query if connector supports operation before retrieving it." This reverts commit 5ac92014da2682bdba62d7a2524b8d90e38f6b19. * Committing clang-format changes * Convert attribute 'get' operation to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. * Update tracing macros * Convert attribute 'specific' operation to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. * Convert dataset 'get' and 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Also, minor tweaks to attribute 'get' and 'specific' operation parameters. * Convert datatype 'get' and 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Also, minor tweaks to H5O_refresh_metadata arguments. * Reduce warnings * Reduce warnings * Track change to datatype 'get' callback * Fix bug with file pointer getting invalidated when object closed * Reformat source * Convert file and group VOL classes 'get' and 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Also small cleanup to the attribute get name operation. Also moved 'mount' and 'unmount' operations to be group specific operations, instead of file specific, to better align with their behavior (mounted files are on groups, so a group is what is operated on). * Remove remainder of merge conflict marking * Convert link VOL class 'create' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. * Remove some unused local variables * Convert link VOL class 'get' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Also refactor 'get name by idx' routines to return actual length of name with a parameter instead of the return value, and move some callback context structs for the link interface from the private header file into the source code module, to reduce their visibility scope. * Update tracing macros * Convert link VOL class 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. * Convert object VOL class 'get' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. * Convert object VOL class 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Also refactor H5G_loc_exists, et al, to return 'exists' flag in a parameter and errors with the function return value, instead of overloading both into the return value. And, corrected logic error in test/links.c around non-existant objects in a file. * Convert request VOL class 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. * Convert blob VOL class 'specific' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Also removes the H5VL_BLOB_GETSIZE operation, as it's unused in the library and the blob ID size for a container is now returned with H5VL_FILE_GET_CONT_INFO. * Add 'const' to several parameters that are only queried. * Convert all VOL classes' 'optional' operations to use struct-of-tagged-union pattern for VOL callback arguments, instead of using varargs. Convert several 'get' routines to return the length of an array in a parameter instead of combining it into the return value. Move several routines to be in less public namespace. Correct direct_chunk test to verify that parameters aren't modified on error. * Switch get/specific/optional VOL callback argument structures to be 'async-friendly'. Also other minor cleanups and bug-fixes. * Add H5Pset_dataset_io_hyperslab_selection / H5S_PLIST feature, to allow skipping H5Dget_space + H5Sselect_hyperslab for async operation * Add dynamic optional operations for request objects * Update dynamic operation test for optional request operations * Update a comment for an operation argument * Run trace and format_source scripts * Committing clang-format changes * Committing clang-format changes Co-authored-by: vchoi <vchoi@jelly.ad.hdfgroup.org> Co-authored-by: vchoi-hdfgroup <55293060+vchoi-hdfgroup@users.noreply.github.com> Co-authored-by: jhendersonHDF <jhenderson@hdfgroup.org> Co-authored-by: Dana Robinson <derobins@hdfgroup.org> Co-authored-by: Dana Robinson <43805+derobins@users.noreply.github.com> Co-authored-by: bmribler <39579120+bmribler@users.noreply.github.com> Co-authored-by: github-actions <41898282+github-actions[bot]@users.noreply.github.com>

| | | | | | | | | | | | | | | | | * We assume that fseeko and ftello exist. * The *64 IO functions and types are no longer explicitly used. We now rely on a mapping provided by _FILE_OFFSET_BITS (or its equivalent). * _LARGEFILE(64)_SOURCE is no longer exposed via AM_CPPFLAGS. The CMake files have not yet been updated but CMake is still functional. The CMake configure files will just run a few unecessary tests and create unneeded #defines until they are updated in a few days. Tested on: Linux, OS X, Solaris, z/OS

* [svn-r19188] Bug fix: ID 1917Albert Cheng2010-08-061-32/+47
| | | | | | | | | | | The STDIO only checked for fseeko and incorrectly assumed it can support file sizes larger than 32bits. Fixed it by making to use fseeko64 if supported, else use fseeko. To simplify the code, assume fseeko which is a POSIX function must be supported. Therefore, fseek is not used at all. (Note: the above applies to Unix-like system. The Windows platform has hardcoding using Windows functions which are NOT POSIX compliant.) Tested: h5committested. Also tested in BP (AIX) 32/64 and enable/disable-largefile.
