* [svn-r8731] Purpose:Quincey Koziol2004-06-231-9/+6
| | | | | | | | | | | | | | | Code cleanup & minor optimization Description: Re-work the way interface initialization routines are specified in the library to avoid the overhead of checking for them in routines where there is no interface initialization routine. This cleans up warnings with gcc 3.4, reduces the library binary size a bit (about 2-3%) and should speedup the library's execution slightly. Platforms tested: FreeBSD 4.10 (sleipnir) w/gcc34 h5committest
* [svn-r8677] Purpose:Quincey Koziol2004-06-141-3/+3
| | | | | | | | | | | | | | | | | | | Code cleanup & optimization Description: Remove old structures that used a union to store information about the dataspace extent and just store the information directly in the dataspace extent itself. Remove ifdef'd references to permutation ordering in dataspaces. We'll definitely need more than this code if/when we implement this feature. Change allocation of dataspace information from calloc() to malloc(). Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.10 (sleipnir) w/parallel Too minor to require h5committest
* [svn-r8673] Purpose:Quincey Koziol2004-06-131-6/+6
| | | | | | | | | | | | | | | | | | Code optimization Description: Revised dataspace selections to use a more "object oriented" mechanism to set the function pointers for each selection and selection iterator. This reduces the amount and number of times that dataspace selection info has to be copied. Additionally, change hyperslab selection information to be dynamically allocated instead of an inline struct.

* [svn-r8613] Purpose:Quincey Koziol2004-06-051-25/+20
| | | | | | | | | | | | | | | | | Refactor code Description: Move chunk and contiguous cached raw data from file information to dataset information. This simplifies a number of internal interfaces, aligns the code with it's purpose better and should allow more optimizations to the chunked data I/O performance.

* [svn-r8590] Purpose:Quincey Koziol2004-05-271-3/+3
| | | | | | | | | | | | | | | | | | | | | Code optimization & bug fix Description: When dimension information is being stored in the storage layout message on disk, it is stored as 32-bit quantities, possibly truncating the dimension information, if a dimension is greater than 32-bits in size. Solution: Fix the storage layout message problem by revising file format to not store dimension information, since it is already available in the dataspace. Also revise the storage layout data structures to be more compartmentalized for the information for contiguous, chunked and compact storage.

* [svn-r8158] Purpose:Quincey Koziol2004-02-061-14/+13
| | | | | | | | | | | | | | | | | Code cleanup/optimization Description: Query property list values once, at the beginning of the I/O routines, instead of querying the property list values multiple (lots!) of times in lower level routines. Solution: Create "property list caches" for internal library queries of the property list values. Platforms tested: IBM p690 (copper) w/parallel & fphdf5 h5committest
* [svn-r8126] Purpose:Quincey Koziol2004-01-311-2/+2
| | | | | | | | | | | | | | | | | Bug fix/optimization Description: Address slowdown in MPI-I/O file metadata operations that was introduced mid-stream. We now _require_ a POSIX compliant parallel file system for the MPI-I/O file driver (as well as for the MPI-POSIX file driver). Also optimized file open operation when the file is being created by reducing the number of collective & syncronizing calls. Additionally, refactor the MPI routines into a common place, eliminating duplicated code. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel h5committest
* [svn-r7917] Purpose:Quincey Koziol2003-12-061-5/+5
| | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up compiler warnings, especially the 'FUNC' variable not used which comes out in production mode. Solution: Had to add a new FUNC_ENTER_NOAPI_NOINIT_NOFUNC macro for those non-API functions which don't need the 'FUNC' variable defined. (This will be _so_ much easier when C99 is standard on all our supposed platforms, since it has a __FUNC__ macro... ) Platforms tested: FreeBSD 4.9 (sleipnir) too minor for h5committest (although there were lots of files changed, the change was minor in each one)
* [svn-r7794] Purpose:Quincey Koziol2003-10-301-203/+107
| | | | | | | | | | | | | | | | | | Code cleanup & simplification Description: Replace [non-working] code in routine to build up an MPI derived type for a hyperslab selection that was supposed to "flatten" out contigous blocks with code that uses a selection iterator (which _does_ have working "flattening" code). Remove "contiguous hyperslab" code for MPI selections as it is unnessary now.

* [svn-r7789] Purpose:Quincey Koziol2003-10-291-161/+47
| | | | | | | | | | | | | | | Bug fix & code cleanups Description: Change our use of MPI derived datatypes to not create datatypes with "0-sized" lengths, which causes the LANL Q machine to hang. Also, get rid of "prefer MPI derived datatypes" environment variable since it has no advantage. Platforms tested: FreeBSD 4.9 (sleipnir) w & w/o parallel h5committest

| | | | | | | | | | | | | Refactoring code Description: Refactored "IS_H5FD_MPIO || IS_H5FD_MPIPOSIX || IS_H5FD_FPHDF5" combination of macros in many places into single IS_H5FD_MPI macro, which has the same definition, but should be easier to maintain.

Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings.

| | | | | | | | | | | | | | 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.
* [svn-r6047] Purpose:Quincey Koziol2002-11-011-1/+1
| | | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Hyperslab code for collapsing dimensions was incorrectly collapsing selections inappropriately when the fastest changing dimension couldn't be collapsed. Also add some more assertions which will make similar bugs easier to find. Solution: Break out of loop earlier. Platforms tested: modi4 (parallel), too small to triple check.
* [svn-r6043] Purpose:Quincey Koziol2002-10-291-1/+78
| | | | | | | | | | | | Bug fix Description: I/O using "none" selections in parallel wasn't working correctly. Also, add serial "none" selection test. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}
* [svn-r5894] Purpose:Quincey Koziol2002-08-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix/Code cleanup/New Feature Description: Correct problems with writing fill-values to external storage and allocate the data storage at the correct times. Also, mostly straighten out the strange code which allocates and fills raw data storage for datasets. Things are still a bit odd in that the fill-values for chunked datasets are written when the space is allocated, instead of in a separate routine, but there are two reasons for this: it's inefficient (especially in parallel) to iterate through all the chunks twice, and (more importantly) the space needed to store compressed chunks isn't known until we've got a buffer of compressed fill-values ready to write to the chunk. Additionally, add in the H5D_SPACE_ALLOC_INCR and H5D_SPACE_ALLOC_DEFAULT setting for the "space time", which incorporate the previous behavior of the space allocation for chunked datasets. The default settings for the different types of dataset storage are now as follows: Contiguous - Late Chunked - Incremental Compact - Early This checkin also incorporates a change to the behavior of external data storage in two ways - fill-values are _never_ written to external storage (under the assumption that writing fill-values is triggered by allocating space in an HDF5 file, and since space is not allocated in the file, the fill-values should not be written) and external data files are now created if they don't exist when data is written to them. The fill-value will probably need to be revisited at some time in the future, this just seemed like the safer course currently. I think I cleaned up some compiler errors also, before getting bogged down in the fixes for the space allocation and fill-values. Platforms tested: FreeBSD 4.6 (sleipnir) w/serial & parallel. Will be testing on IRIX64 6.5 (modi4) in serial & parallel shortly.
* [svn-r5871] Purpose:Quincey Koziol2002-08-121-1/+0
| | | | | | | | | | | | | | | | Code cleanup Description: Combined H5P_isa_class and H5I_object functionality into a new internal H5P API function: H5P_object_verify, which checks that a property list is the appropriate class and then returns the property list object associated with the property list ID. This reduces the source code by about 200 LOC and trims the library binary some more. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5867] Purpose:Quincey Koziol2002-08-091-0/+2
| | | | | | | | | | | | | Code cleanup Description: Changed the last HRETURN* statements in the FUNC_ENTER macros into HGOTO* macros, which reduces the size of the library binary in certain configurations by another 10% Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel, IRIX64 6.5 (modi4) serial & parallel
* [svn-r5842] Purpose:Quincey Koziol2002-08-081-61/+60
| | | | | | | | | | | | | | | | Code cleanup Description: Change most (all?) HRETURN_ERROR macros to HGOTO_ERROR macros, along with HRETURN macros to HGOTO_DONE macros. This unifies the error return path from functions and reduces the size of the library by up to 10% on some platforms. Additionally, I improved a lot of the error cleanup code in many routines. Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel and IRIX64 6.5 (modi4) serial & parallel.
* [svn-r5839] Purpose:Quincey Koziol2002-07-311-4/+4
| | | | | | | | | | | | | | | Code cleanup Description: Move operations on each type of selection into the source code file for each selection type (all->H5Sall.c, hyperslab->H5Shyper.c, etc.) Remove central H5S_select_<foo> operations, instead calling the operations through function pointers in each selection (a much more object-oriented approach). Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5707] Purpose:Quincey Koziol2002-06-251-0/+4
| | | | | | | | | | | | | | Bug Fix. Description: Contiguous types created for "all" and contiguous hyperslab selections was not being committed before using them. Solution: Commit them. :-) This fixes the problems on the LLNL Blue Pacific machine. Platforms tested: LLNL Blue Pacific w/parallel.
* [svn-r5680] Purpose:Quincey Koziol2002-06-191-28/+80
| | | | | | | | | | | | | | | | | | | | New feature. Description: There is some discussion among the SAF team as to whether it is better to use MPI derived types for raw data transfers (thus needing a MPI_File_set_view() call), or whether it is better to use a sequence of low-level MPI types (i.e. MPI_BYTE) for the raw data transfer. Solution: Added an in internal flag to determine whether derived types are preferred (the default), or whether they should be avoided. An environment variable ("HDF5_MPI_PREFER_DERIVED_TYPES") can be set by users to control whether MPI types should be used or not. Set the environment variable to "0" (i.e.: 'setenv HDF5_MPI_PREFER_DERIVED_TYPES 0' to avoid using MPI derived types. Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5660] Purpose:Quincey Koziol2002-06-181-88/+197
| | | | | | | | | | | | Code optimization Description: Avoid creating MPI types (and thus requiring a MPI_File_set_view() call) when contiguous selections are used for dataset I/O. This should be a performance improvement for those sorts of selections. Platforms tested: Linux 2.2.x (eirene) w/parallel && IRIX64 6.5 (modi4) w/parallel & FORTRAN
* [svn-r5652] Purpose:Quincey Koziol2002-06-171-3/+12
| | | | | | | | | | | | Code cleanup Description: Use dataset transfer property list to hold information about the MPI types for the current transfer, instead of setting pseudo-global variables in the file's struct. Platforms tested: Linux 2.2.x (eirene) w/parallel & IRIX64 6.5 (modi4) w/parallel & FORTRAN
* [svn-r5650] Purpose:Quincey Koziol2002-06-171-11/+14
| | | | | | | | | | | | Code cleanup Description: Change MPI-I/O code to use the address of the dataset for the displacement, instead of having a separate displacement value. Removed displacement parameter from H5FD_mpio_setup parameters. Platforms tested: Linux 2.2.x (eirene) w/parallel & IRIX64 6.5 (modi4) w/parallel.
* [svn-r5530] Purpose:Bill Wendling2002-06-041-0/+3
| | | | | | | | | | | | | | | Code Cleanup Description: Removed some compiler warnings. Solution: In a few cases, NULL was being returned when a FAIL was supposed to be returned instead. There were some header files which needed to be included in a few of the sources. A couple of if-then statements had assignments in the conditional part. The compiler warned that they should have extra "()"s around them. Made the code check the values instead. Platforms tested: Linux (parallel) Modi4 (parallel)
* [svn-r5471] Purpose:Quincey Koziol2002-05-291-3/+3
| | | | | | | | | | | | | | | | Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.
* [svn-r5467] Purpose:Quincey Koziol2002-05-281-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | Code cleanup. Description: Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros equivalents in the SAF library and adapted them to our library. I added an additional macro which is equivalent to FUNC_ENTER: FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but none of the library or interface initialization code. This is to be used _only_ for static functions and those which explicitly cannot have the library or interface initialization code enabled (like the API termination routines, etc.). This allowed many more of the functions in the library [but not all yet :-(] to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs. It also reduced the size of the library and executables (by cutting out a bunch of code which was never executed), I'll e-mail the exact results when I've finished editing it. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5259] Purpose:Quincey Koziol2002-04-251-19/+11
| | | | | | | | | | | | | | | | Code cleanup Description: Previously, the I/O pipeline (pline), external file list (efl) and fill- value (fill) structs were passed down the raw data function call chain, even into and/or through functions which didn't use them. Since all three of these pieces of information are available from the dataset creation property list, just pass the dataset creation property list down the function call chain and query for the information needed in a particular function. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5139] Purpose:Quincey Koziol2002-04-031-1/+1

* [svn-r5138] Purpose:Quincey Koziol2002-04-031-33/+74
| | | | | | | | | | | | | | | | | | | | | | Bug Fix & Code Cleanup Description: The MPI-IO optimized transfer routines (H5S_mpio_spaces_read/H5S_mpio_space_write) are not being invoked in all the cases where they could be used. Additionally, the code for determining if an optimized transfer is wrapped into the actual I/O transfer routine in a very confusing way. Solution: Re-enabled MPI-IO optimized transfer routines in all the cases where they should work. Extracted all the pre-conditions for optimized transfers into separate routines from the transfer routines. Platforms tested: FreeBSD 4.5 (sleipnir) & IRIX64 6.5 (modi4)

* [svn-r4965] Purpose:Quincey Koziol2002-02-141-7/+10
| | | | | | | | | | | | | Bug Fix Description: If a non-zero fill-value is used for a chunked dataset, any non-existent chunked read with an "all" selection (or a contiguous hyperslab selection) will return zero for those instead of the user's fill-value. Solution: Fixed I/O code to pass down fill-value to "optimized" I/O routines, so it will be available to fill the user's buffer with. Platforms tested: FreeBSD 4.5 (sleipnir)

* [svn-r4643] Purpose:Quincey Koziol2001-11-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Windows is generating hundreds of warnings from some of the practices in the library. Mostly, they are because size_t is 32-bit and hsize_t is 64-bit on Windows and we were carelessly casting the larger values down to the smaller ones without checking for overflow. Also, some other small code cleanups,etc. Solution: Re-worked some algorithms to eliminate the casts and also added more overflow checking for assignments and function parameters which needed casts. Kent did most of the work, I just went over his changes and fit them into the the library code a bit better. Platforms tested: FreeBSD 4.4 (hawkwind)

| | | | | | | | | | | | | | | | | | | | | | Code cleanup (sorta) Description: When the first versions of the HDF5 library were designed, I remembered vividly the difficulties of porting code from a 32-bit platform to a 16-bit platform and asked that people use intn & uintn instead of int & unsigned int, respectively. However, in hindsight, this was overkill and unnecessary since we weren't going to be porting the HDF5 library to 16-bit architectures. Currently, the extra uintn & intn typedefs are causing problems for users who'd like to include both the HDF5 and HDF4 header files in one source module (like Kent's h4toh5 library). Solution: Changed the uintn & intn's to unsigned and int's respectively. Platforms tested: FreeBSD 4.4 (hawkwind)

| | | | | | | | | | Code cleanups, mostly.. Description: Work on pacifying the SGI compiler to get the generic properties working correctly with --enable-parallel and --enable-fortran. It's not quite fixed yet, but I need to head home and these patches help... :-/ Platforms tested: IRIX64 6.5 (modi4)
* [svn-r4324] Purpose:Quincey Koziol2001-08-101-10/+19
| | | | | | | | | | | | | | | | | | | | | | | | New Features! Description: Start migrating the internal use of property lists in the library from the older implementation to the new generic property lists. Currently, only the dataset transfer property lists are migrated to the new architecture, all the rest of the property list types are still using the older architecture. Also, the backward compatibility features are not implemented yet, so applications which use dataset transfer properties may need to make the following changes: H5Pcreate(H5P_DATASET_XFER) -> H5Pcreate_list(H5P_DATASET_XFER_NEW) and H5Pclose(<a dataset transfer property list>) -> H5Pclose_list(id) This still may have some bugs in it, especially with Fortran, but I should be wrapping up those later today. Platforms tested: FreeBSD 4.4 (hawkwind)
