* [svn-r7029] Purpose:Quincey Koziol2003-06-121-22/+54
| | | | | | | | | | | | | New feature/Bug fix Description: Add new fill time value - H5D_FILL_TIME_IFSET which writes the fill value to a dataset if the user has defined one, otherwise not writing the fill value to the dataset. Platforms tested: FreeBSD 4.8 (sleipnir) serial & parallel h5committest
* [svn-r7008] Purpose:Quincey Koziol2003-06-091-1/+1
| | | | | | | | | | | | | Bug fix Description: Correct file->mpi->size to just mpi_size. Platforms tested: FreeBSD 4.8 (sleipnir) Misc. update: Reported by: Bill
* [svn-r7007] Purpose:Quincey Koziol2003-06-091-1/+1
| | | | | | | | | | | | | | Bug fix. Description: Changed "x=(x++)%y" to "x=(x+1)%y", since the former was not guaranteed to compile to the latter. Platforms tested: Eyeballed. Misc. update: Pointed out by: Forsythe, Christi <caforsy@sandia.gov>
* [svn-r6942] Purpose:Quincey Koziol2003-05-311-0/+24
| | | | | | | | | | | | | | | | | Performance improment Description: Speed up chunked dataset I/O. This breaks down into several areas: - Compute chunk selections in the file by using hyperslab operations instead of iterating over each element in the selection. - If the file and memory selections are the same shape, use the file chunk selections to compute the memory chunk selections. This required several additional dataspace, dataspace selection and hyperslab routines. Platforms tested: h5committestted (although Fortran tests failed for some reason)
* [svn-r6878] Purpose:Quincey Koziol2003-05-151-1/+2
| | | | | | | | | | | Code cleanup Description: Limit the scope on more function prototypes/macros/typedefs. Platforms tested: FreeBSD 4.8 (sleipnir) h5committest not necessary.
* [svn-r6843] Purpose:Quincey Koziol2003-05-091-1/+1
| | | | | | | | | | | | Code cleanup Description: Clean up warnings exposed by compiling on O2K. Also, revert some of Bill and my changes to the H5S_mpi_opt_types_g, etc. and settle them back into their original location. Platforms tested: h5committested.
* [svn-r6837] Purpose:Quincey Koziol2003-05-081-2/+2
| | | | | | | | | | | | | | | Code cleanup. Description: Move many package or internal function prototypes and macro definitions into tighter scope according to their current use. Added more comments where appropriate. Eliminate ancient, unused functions. Added a couple "accessor" functions to get parts of data structures which were moved out of scope. Platforms tested: h5committested
* [svn-r6825] Purpose:Quincey Koziol2003-05-071-280/+151
| | | | | | | | | | | | | | | | | | | | | | | | | New feature/enhancement Description: Chunked datasets are handled poorly in several circumstances involving certain selections and chunks that are too large for the chunk cache and/or chunks with filters, causing the chunk to be read from disk multiple times. Solution: Rearrange raw data I/O infrastructure to handle chunked datasets in a much more friendly way by creating a selection in memory and on disk for each chunk in a chunked dataset and performing all of the I/O on that chunk at one time. There are still some scalability (the current code attempts to create a selection for all the chunks in the dataset, instead of just the chunks that are accessed, requiring portions of the istore.c and fillval.c tests to be commented out) and performance issues, but checking this in will allow the changes to be tested by a much wider audience while I address the remaining issues. Platforms tested: h5committested, FreeBSD 4.8 (sleipnir) serial & parallel, Linux 2.4 (eirene)

* [svn-r6505] Purpose:Bill Wendling2003-03-191-9/+11
| | | | | | | | | | | | | | | | | Update Description: Have the FPHDF5 module initialized on startup. Have only the captain process perform certain functions (like flushing during an F_close call or allocating the superblock). H5Fistore needed a few checks to see if it was working with an FPHDF5 driver. Done similarly to how MPI and MPIPOSIX drivers are checked.. Platforms tested: Linux, Modi4, Sol Misc. update:

| | | | | | | | | | | | | | | | | | | Finish code cleanup Description: Wrap up the conversion of H5F_flush's multiple boolean flags into a single bitfield of flags by pushing the flags down into the H5AC_flush and H5F_istore_flush routines. Also, changed the flags from H5_FLUSH_<foo> to H5F_FLUSH_<foo> to be more consistent with rest of library. And reverted the changes to H5FDflush and H5FD_flush routines.

| | | | | | | | | | | | Update Description: Final support addition for FPHDF5. Wherever there was an equivalent MPIO or MPIO/POSIX call/check, I placed an FPHDF5 call/check there as well, with the appropriate #ifdefs in place. The hdf5.h is updated with the H5FDfphdf5.h driver #include. Platforms tested: Linux & Modi4
* [svn-r6411] Purpose:Quincey Koziol2003-02-171-15/+25
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Clean up miscellaneous warnings which have crept into the code. Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD. Adjust gcc compiler flags to be more concise for production mode. Refactor the H5O code so that there is a stronger boundary between code in the H5O package and code in the library which just calls H5O routines. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel and gcc 2.95.4 & gcc 3.2.2 Misc. update: Update MANIFEST if you add or remove any file.

* [svn-r6387] Purpose:Quincey Koziol2003-02-101-73/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lots of performance improvements & a couple new internal API interfaces. 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.

* [svn-r6106] Purpose:Quincey Koziol2002-11-201-44/+39
| | | | | | | | | | | | | | | | | | | | | | | | | Code cleanup, Feature enhancement Description: Improve hashing algorithm to not generate as many clashes. Avoid using H5MD_realloc when changing the size of a chunk on disk. Instead, use H5MF_free followed by H5MF_alloc, which avoids copying the information from the space for the previous chunk to the space for the new chunk, since we are going to overwrite the chunk with new data anyway. This change should both improve I/O performance in situations where compressed chunks are being overwritten as well as reduce the space used in the file during that situation. Cleaned up error handling in a few cases. Removed old debugging printf()s. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir)
* [svn-r5894] Purpose:Quincey Koziol2002-08-271-29/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-r5886] Purpose:Quincey Koziol2002-08-231-0/+14
| | | | | | | | | | | | | | Bug fix Description: Correctly apply filters (like compression) to fill values in chunks that are pre-allocated. This is OK in parallel also, since all the chunks are identical at this point and any chunk may be written by any process. Platforms tested: FreeBSD 4.6 (sleipnir) w/parallel
* [svn-r5875] Purpose:Quincey Koziol2002-08-141-31/+55
| | | | | | | | | | | | | | Additional regression tests & bug fixes Description: There was no testing for the H5Dget_storage_size function and it seemed to be having problems with compressed, chunked datasets, so write some tests to verify that its working correctly. Also, fix case for allocating storage early for chunked datasets Platforms tested: FreeBSD 4.6 (sleipnir) serial & parallel
* [svn-r5871] Purpose:Quincey Koziol2002-08-121-4/+1
| | | | | | | | | | | | | | | | 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 Koziol2002-08-091-18/+28
| | | | | | | | | | | | | 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 Koziol2002-08-081-158/+137
| | | | | | | | | | | | | | | | 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 Koziol2002-07-311-1/+1
| | | | | | | | | | | | | | | 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-r5799] Purpose:Quincey Koziol2002-07-151-11/+33
| | | | | | | | | | | | New feature. Description: Added MPI-posix VFL driver. This driver uses MPI to coordinate actions, but performs I/O directly with posix sec(2) I/O functions. This driver should _NOT_ be used if the file accessed is not on a parallel filesystem. Platforms tested: FreeBSD 4.6 (sleipnir) w/parallel & IRIX64 6.5 (modi4) w/parallel
* [svn-r5674] Purpose:Quincey Koziol2002-06-191-3/+4
| | | | | | | | | | Code cleanup Description: Removed more compiler warnings, etc. Platforms tested: Linux 2.2.x (eirene) w/parallel
* [svn-r5662] Purpose:Quincey Koziol2002-06-181-105/+11
| | | | | | | | | | | | | | | | | Bug fix. Description: The chunking code was using internal allocation routines to put blocks on a free list for reuse, instead of using the system allocation routines (ie. malloc, free, etc.). This causes problems when user filters attempt to allocate/free chunks for their algorithm's use. Solution: Switched the chunking code back to using the system allocation routines, we can address performance issues with them if it becomes a real problem. Platforms tested: Linux 2.2.x (eirene) && IRIX64 6.5 (modi4)
* [svn-r5571] Purpose:Quincey Koziol2002-06-101-4/+5

* [svn-r5530] Purpose:Bill Wendling2002-06-041-1/+1
| | | | | | | | | | | | | | | 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 Koziol2002-05-291-25/+27
| | | | | | | | | | | | | | | | 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 Koziol2002-05-281-11/+19
| | | | | | | | | | | | | | | | | | | | | | | | 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-r5434] Purpose:Quincey Koziol2002-05-171-26/+39
| | | | | | | | | | | | | Code improvement. Description: Propagated the "fill time" property into the parallel chunk allocation routine, allowing it to avoid writing fill values to each new chunk allocated. This improves the performance of chunked datasets in parallel I/O to be on par with contiguous datasets again (on modi4). Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5429] Purpose:Quincey Koziol2002-05-171-65/+102
| | | | | | | | | | | | | | | | | | | | | Bug fix/Code improvement. Description: Currently, the chunk data allocation routine invoked to allocate space for the entire dataset is inefficient. It writes out each chunk in the dataset, whether it is already allocated or not. Additionally, this happens not only when it is created, but also anytime it is opened for writing, or the dataset is extended. Worse, there's too much parallel I/O syncronization, which slows things down even more. Solution: Only attempt to write out chunks that don't already exist. Additionally, share the I/O writing between all the nodes, instead of writing everything with process 0. Then, only block with MPI_Barrier if chunks were actually created. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5271] Purpose:Quincey Koziol2002-04-261-1/+5
| | | | | | | | | | | | | | | | Bug Fix. Description: When the fill value for a dataset is not set, the size is set to zero, causing problems with filling unused areas in previously defined chunks (i.e. when the dataset shrinks in size) Solution: Use the size of the elements in the dataset directly, instead of relying on the size of the fill value (which must be the same size). Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5259] Purpose:Quincey Koziol2002-04-251-180/+143
| | | | | | | | | | | | | | | | 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-r5230] Purpose:Quincey Koziol2002-04-231-57/+76
| | | | | | | | | | | | | | | | | Code cleanup Description: Clean up the H5B_iterate code to not have a single hard-wired iterator for each interface which uses a B-tree, instead accept a function pointer which determines the callback function. This allows additional iterator callbacks to be defined without requiring additional H5B functions to be created. In that spirit, remove the H5B_prune_by_extent call and convert the H5F_istore callback routine for it into a callback routine for H5B_iterate. Platforms tested: FreeBSD 4.5 (sleipnir)

| | | | | | | | | | | | | | | | | | | | | | Bug Fix & Feature Description: The selection offset was being ignored for optimized hyperslab selection I/O operations. Additionally, I've found that the restrictions on optimized selection I/O operations were too strict and found a way to allow more hyperslabs to use the optimized I/O routines. Solution: Incorporate the selection offset into the selection location when performing optimized I/O operations. Allow optimized I/O on any single hyperslab selection and also allow hyperslab operations on chunked datasets. Platforms tested: FreeBSD 4.5 (sleipnir)
