* [svn-r3302] Purpose:Quincey Koziol2001-01-181-65/+102
| | | | | | | | | | | | | Bug fix Description: Certain combinations of hyperslabs, especially those that have to be strip-mined during I/O were causing data to be incorrectly transferred. Solution: Changed the code in H5S_get_hyper_regions to be more careful about the regions of the current dimension that are valid. Sometimes, regions which had already been iterated through were being re-processed. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r3252] Purpose:Quincey Koziol2001-01-091-358/+371
| | | | | | | | | | | | | Code cleanup. Description: Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the extra warnings. Including a few show-stoppers for compression on IRIX machines. Solution: Changed lots of variables' types to more sensible and consistent types, more range-checking, more variable typecasts, etc. Platforms tested: FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)
* [svn-r3065] Purpose:Quincey Koziol2000-12-021-4/+4
| | | | | | | | Code cleanup Description: Remove some warnings... Platforms tested: FreeBSD 4.2 (hawkwind) & IRIX64 6.5 (modi4)
* [svn-r3061] Purpose:Quincey Koziol2000-12-011-10/+51
| | | | | | | | | | | | | | Bug fix. Description: Cray T3E (and J90?) was failing on partial I/O tests. The bug was in the optimized hyperslab routines for cases where a hyperslab filled the temporary datatype conversion buffer and the optimized hyperslab routine needed to start in the middle of a hyperslab. Solution: Corrected code to detect the situation and read in the correct amount of elements in the hyperslab. Platforms tested: Cray T3E (mcurie.nersc.gov)
* [svn-r2804] Purpose:Quincey Koziol2000-11-071-0/+4
| | | | | | | | | | | | Bug Fix Description: Selections in 1-D dataspaces would get into an infinite loop in H5S_hyper_select_iterate_mem_opt (called by H5Diterate and H5Dget_vlen_buf_size) due to some incorrect logic. Solution: Handled 1-D cases correctly and get out of loop. Platforms tested: Eyeballed...
* [svn-r2736] Purpose:Quincey Koziol2000-10-251-218/+274
| | | | | | | | | | Code optimization Description: Minor tweaks throughout the optimized regular hyperslab code to increase speed. This set of improvements increase the benchmark time from taking ~5.46 seconds to ~4.50 seconds, or around a 20% further speedup. Platforms tested: Solaris 2.6 (baldric)
* [svn-r2707] Purpose:Quincey Koziol2000-10-191-15/+91
| | | | | | | | | | | | | Optimization for parallel I/O Description: When contiugous hyperslabs are defined (i.e. with the block=stride), the library was only aggregating the hyperslabs together for the fastest changing dimension. Solution: Add some extra code to detect when contiguous hyperslabs span more than one row and output the entire contiguous section at once. Platforms tested: FreeBSD 4.1.1 (hawkwind)
* [svn-r2657] Quincey Koziol2000-10-101-274/+19
| | | | | | | | | | | | Purpose: Parallel Bug Fixes Description: Was out of sync with header file re-arrangements I checked in last night. Solution: Fixed to use new header files, etc. Platforms tested: O2K (modi4)
* [svn-r2652] Purpose:Quincey Koziol2000-10-101-50/+94
| | | | | | | | | | | | | | | Maintainance & performance enhancements Description: Re-arranged header files to protect private symbols better. Changed optimized regular hyperslab I/O to compute the offsets more efficiently from previous method of using matrix operations. Added sequential I/O operations at a more abstract level (at the same level as H5F_arr_read/write), to support the optimized hyperslab I/O. Platforms tested: Solaris 2.6 (baldric) & FreeBSD 4.1.1 (hawkwind)
* [svn-r2647] Purpose:Albert Cheng2000-10-101-15/+19
| | | | | | | | | | | | | | Bug fiX Description: H5S_hyper_select_valid would report hyperslab invalid if the one of the count values is zero. The verifying algorithm did not take into consideration that block or count can contain zeros to indicate no element is wanted. Solution: Added code to test if block or count is zero. If so, skip the rest of the validity check. Platforms tested: IRIX64 -64.
* [svn-r2610] Purpose:Quincey Koziol2000-09-281-28/+325
| | | | | | | | | | | | | | | | | | Code Optimization. Description: The optimized routines for copying regular hyperslabs in memory have been using the same matrix routines to copy their hyperslab pieces as the routines for irregularly shaped hyperslabs. This ends up imposing lots of extra overhead on the optimized routine, since it basically "knows" all the matrix information it needs. Solution: Keep track of the [small] amount of matrix information necessary to perform the regular hyperslab copies in the optimized routines themselves instead of using the matrix routines. This improves the performance for the benchmark I'm running from ~18 seconds to ~12 seconds and should apply to parallel I/O situations also. Platforms tested: Solaris 2.6 (i.e. baldric)
* [svn-r2594] Purpose:Quincey Koziol2000-09-261-24/+18
| | | | | | | | | | | | Small Code Cleanup Description: Code to optimize adjacent (i.e. contiguous) hyperslab was ugly and used too many temporary variables. Solution: Computed the optimized hyperslabs slightly differently and got rid of unnecessary temporary variables. Platforms tested: FreeBSD 4.1
* [svn-r2587] Purpose:Quincey Koziol2000-09-221-2/+56
| | | | | | | | | | | | | | | | | | | Bug fix (sorta) Description: When the stride and block size of a hyperslab selection are equal, the blocks that are selected are contiguous in the dataset. Prior to my hyperslab optimizations, this situation used to be detected and somewhat optimized to improve performance. I've added more code to optimize for this situation and integrated it with the new hyperslab optimization that weren't very efficient for that case as they should have been. Solution: Detect contiguous hyperslab selections (i.e. block size in a dimension is the same as the stride in that dimension) and store the optimized, contiguous version of that hyperslab. We also store the original, un- optimized version of the hyperslab to give back to the user if they query the hyperslab selection they just made. Platforms tested: FreeBSD 4.1

* [svn-r2544] Optimized regular hyperslab I/O routines and data structures. ↵Quincey Koziol2000-09-131-293/+1767
| | | | | | | | | | | | | On my benchmarks, they are about 4-5 times faster than before. We no longer generate "general" hyperslab data structures for regular hyperslabs, the general data structures are only generated when needed for irregular hyperslabs. Still fixing a couple of nook-and-cranny functions to understand the new information for the regular hyperslabs, so the tests aren't completely passing, but I wanted to get this checked in for Elena's benchmarks. I should have more/all tests passing later today.

I've ported and tested the sec2, family, and core drivers and only ported the mpio driver (Albert will test it). So if you need MPIO I would recommend sticking with the previous version for a while. You will get a few compile warnings about split and stdio drivers not being implemented and possibly tracing information not inserted in some of the drivers. You can safely ignore them but I plan to fix them. I'm still working on the split driver because I just realized that it needs a part of the VFL that isn't written yet. Documentation is being updated also because there were some minor changes (mostly just name changes). It should be available on my web site later this week. ./MANIFEST ./src/Makefile.in ./src/hdf5.h ./src/H5Flow.c [REMOVED] ./src/H5Fstdio.c [REMOVED] ./src/H5Fsec2.c [REMOVED] ./src/H5Fsplit.c [REMOVED] ./src/H5Fmpio.c [REMOVED] ./src/H5Ffamily.c [REMOVED] ./src/H5Fcore.c [REMOVED] ./src/H5MFpublic.h [REMOVED] ./src/H5FD.c [NEW] ./src/H5FDcore.c [NEW] ./src/H5FDcore.h [NEW] ./src/H5FDfamily.c [NEW] ./src/H5FDfamily.h [NEW] ./src/H5FDmpio.c [NEW] ./src/H5FDmpio.h [NEW] ./src/H5FDprivate.h [NEW] ./src/H5FDpublic.h [NEW] ./src/H5FDsec2.c [NEW] ./src/H5FDsec2.h [NEW] Removed/added files for virtual file layer. ./bin/trace ./src/H5.c Removed unused public datatypes and added new VFL public datatypes.

The default file driver is always the sec2 driver and it always optimizes calls to lseek() or lseek64(). ./config/depend.in C preprocessor errors generated during automatic dependency building are sent to /dev/null to prevent them from appearing twice in the make output. ./src/H5AC.c ./src/H5B.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5Gent.c ./src/H5Gnode.c ./src/H5HG.c ./src/H5HL.c ./src/H5O.c ./src/H5Oattr.c ./src/H5Odtype.c ./src/H5Oefl.c ./src/H5Oshared.c ./src/H5T.c ./src/H5detect.c ./test/ohdr.c Changed H5F_ADDR_UNDEF to HADDR_UNDEF to be more consistent with the `haddr_t' datatype which is now a public type. ./src/H5D.c ./src/H5P.c ./src/H5Ppublic.h ./src/H5Tconv.c ./test/cmpd_dset.c ./test/dsets.c ./test/overhead.c ./test/tselect.c ./test/tvltypes.c The H5P_DATASET_XFER constant was changed to H5P_DATA_XFER because the properties apply to all types of I/O operations, not just datasets. ./src/H5B.c ./src/H5Bprivate.h ./src/H5D.c ./src/H5Dpublic.h ./src/H5F.c ./src/H5Farray.c ./src/H5Fistore.c ./src/H5Fprivate.h ./src/H5Fpublic.h ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5HG.c ./src/H5HL.c ./src/H5O.c ./src/H5R.c ./src/H5Sall.c ./src/H5Shyper.c ./src/H5Smpio.c ./src/H5Spoint.c ./src/H5Sprivate.h ./test/big.c ./test/h5test.c ./test/istore.c ./testpar/t_dset.c ./testpar/t_file.c ./tools/h5debug.c ./tools/h5ls.c Modified to work with the virtual file layer by calling H5FD_* functions instead of H5F_low_* functions and by passing file access and data transfer properties by object ID instead of pointer. Changed H5D_transfer_t to H5FD_mpio_xfer_t since the COLLECTIVE vs. INDEPENDENT transfer mode is specific to the MPIO file driver. Moved MPIO-specific stuff into the MPIO driver. ./src/H5B.c ./src/H5D.c ./src/H5Fprivate.h The H5F_mpio_* private functions were renamed and placed in the H5FDmpio driver except those which appeared in H5Smpio.c. ./src/H5E.c ./src/H5Epublic.h Added major error number H5E_VFL for virtual file layer related errors. ./src/H5F.c ./src/H5Fprivate.h Changed the logic that controls whether the boot block is written. Instead of assuming that the first call to write the boot block is only to allocate space, I've added a function argument which makes this explicit. Changed the way files are compared so that a driver-defined comparison function can be called. Files which belong to different drivers are always considered different. Removed H5F_driver_t since file drivers are now identified by object ID instead of a special non-user-extendible datatype. Removed all the hard-coded low-level file properties which have been replaced by the various file drivers. ./src/H5I.c ./src/H5Iprivate.h Added the H5I_inc_ref() which was removed a few months ago since we finally have a use for it. ./src/H5Ipublic.h Added the H5I_VFL object ID type to identify file drivers in the virtual file layer. ./src/H5MF.c ./src/H5MFprivate.h Moved all the allocation/deallocation code into the virtual file layer which allows file drivers to override much of it. ./src/H5P.c ./src/H5Ppublic.h Moved file driver-specific code into the various file driver files. The H5Pcopy() and H5Pclose() functions make calls into the virtual file driver to manage the memory for driver-specific file access and data transfer properties. ./src/H5private.h ./src/H5public.h The `haddr_t' type is now public. ./test/tfile.c Added a few more comments.

This should allow Dave to get the palettes stored in the file correctly and also enable Bob and/or Bruce's indexing stuff. This change should be folded into the documentation for these three functions for the release. Also, I fixed a number of bugs in the hyperslab and point selection iterators for H5Diterate and they are working correctly now.

Also fixed a hard-to-find bug in the hyperslab I/O routines which could cause data to be corrupted when writing out fields to compound datatype data with background preservation turned on and hyperslabs which were large enough to require two I/O passes on a hyperslab block. A pretty obscure situation, but it would be worthwhile for users to upgrade to this code in order to be certain that correct data is being written.

We were storing dependencies for *.o files instead of *.lo files after shared libraries were added. ./config/gnu-flags ./config/linux-gnulibc1 Moved `-march=pentiumpro -mcpu=pentiumpro -malign-double' from the linux file to this file and caused it to depend on the CPU name.

Changed H5D_xfer_* to H5F_xfer_* because these properties are more general than datasets. This also allows some of the lower-level I/O functions to get this information easier. ./src/H5S.c ./src/H5Sall.c Added two new functions H5S_all_read() and H5S_all_write() which are optimizations that copy data directly between file and memory without having to go through the scatter gather step. This knocks quite a bit of time off the I/O and reading/writing entire datasets is a fairly common operation. ./tools/h5ls.c Reports the logical size of data, the allocated size of data, and the percent utilization. ./MANIFEST Removed old pablo files, added new files. Snapshots should now start to work again. ./src/H5D.c ./src/H5Fmpio.c Removed two warnings signed vs. unsigned comparisons and check for overflow.

Thanks to Quincey, the comment no longer applied. ./src/H5T.c Relaxed the H5Tpack() a little so it would pack compound data structures that had non-transient atomic members. ./tools/h5ls.c Added a `-g' (or `--group') flag that causes information to be printed about the specified group instead of the group's contents. (sort of like Unix's `ls -d'). The `-g' can be used in combination with `-r' to print information about the group and its contents.

Also, there are five new API functions for querying selections: H5Sget_select_hyper_nblocks - retrieves the number of hyperslab blocks in current hyperslab selection for a dataspace H5Sget_select_elem_npoints - retrieves the number of element points in current element selection for a dataspace H5Sget_select_hyper_blocklist - retrieves a list of the hyperslab blocks in current hyperslab selection for a dataspace H5Sget_select_elem_pointlist - retrieves a list of the element points in current element selection for a dataspace H5Sget_select_bounds - retrieves a n-dimensional bounding box containing current selection.

| | | | | | | | | | | | | ---------------------- ./src/H5Shyper.c Changed hyperslab offset arrays to signed quantities to get rid of warnings on DEC cluster. ./src/H5Flow.c ./src/H5Fprivate.h Changed the objno argument of H5F_addr_pack() to be unsigned to get rid of warnings on DEC cluster.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5.c ./src/H5private.h Renamed `library_initialize_g' to `H5_libinit_g' to make it conform to our naming scheme. ./src/H5I.c Fixed a bug in H5I_dec_ref() that caused the return value to always be zero instead of the new reference count. ./src/H5.c ./src/H5Odtype.c ./src/H5T.c ./src/H5Tconv.c ./src/H5Tpkg.h ./src/H5Tprivate.h ./src/H5Tpublic.h Added support for enumeration data types. ./src/H5RA.c Renamed H5T_insert() to H5T_struct_insert() and added H5T_enum_insert(). ./src/H5RA.c ./src/H5Shyper.c Added casts to size_t for the third argument of memcpy() to shut up a warning message from insure++. ./src/H5T.c Changed "can't" to "unable to" in some error messages to be more consistent. ./src/H5detect.c If fork() or waitpid() are unavailable then we assume no alignment constraints. Hopefully this is the case only on NT and Intel CPU's don't have alignment constraints. ./src/H5public.h Include <limits.h> because the H5T_NATIVE_CHAR macro needs the definition for CHAR_MIN.

It's a one line change. Changed the way the library is closed so we have more control over the order the interfaces are shut down. Instead of registering an atexit() function for every interface in some haphazard order we just register one: H5_term_library() which then calls the H5*_term_interface() functions in a well-defined order. If the library is closed and then reopened repeatedly by calling H5close() and H5open() in a loop we only add one copy of the library termination functions with atexit(). Termination is a two-step process in order to help detect programming errors that would cause an infinite loop caused by the termination of one interface waking up some other previously terminated interface. The first step terminates the interface and *marks it as unusable*. After all interfaces are terminated then we mark them all as usable again. The FUNC_ENTER() macro has been modified to return failure or to dump core (depending on whether NDEBUG is defined) if we try to call an interface while it's shutting down. ./src/H5.c The H5dont_atexit() function returns failure if it's called more than once or if it's called too late. However, the error stack is not automatically printed on failure because the library might not be initialized yet ./test/chunk.c ./test/flush1.c ./test/flush2.c ./test/iopipe.c ./test/overhead.c ./test/ragged.c Changed the extra cast for Win32 so we do floating point division again -- it was just confusion about precedence and associativity of casting and the C coercion rules. Removed extra carriage returns inserted by broken operating system. ./src/H5Ffamily.c Fixed an bug where H5F_fam_write() lowered the EOF marker for one of the family members causing H5F_fam_read() to read zeros. ./test/h5test.h [NEW] ./test/h5test.c [NEW] ./test/Makefile.in ./test/bittests.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Support library for test files. This isn't done yet but Katie's contractions are ~10 minutes apart so I figured I better back this stuff up just in case I'm not here next week... Eventually all test files will understand HDF5_DRIVER to name the low level file driver and parameters so we can easily test various drivers. They will also understand HDF5_PREFIX to prepend to the beginning of file names which is necessary for testing ROMIO with various drivers. Also, the cleanup function will know how to use the file name prefix and will understand different file driver naming schemes like file families. I'm not sure they'll understand the `gsf:' type prefixes yet. Note, the external test is completely commented out because I'm in the middle of modifying it. It will still compile and run but it doesn't test anything at the moment.
