| | | | | | | | | | | | Purpose: update install_windows.txt remove hdf4-related stuff in the install_windows.txt modify the this file to reflect the retirement of HAVE_*** in HDF5 configuration process. Description: 1) hdf4 related tools have been moved out of HDF5 CVS tree, The install doc should reflect this. 2) Albert finished macro changes from HAVE_*** to H5_HAVE_***. The doc should reflect this. Solution: Platforms tested:

| | | | | | | | | | | | | | | | | | | | | | | | | | | Merged in a bunch of changes Quincey made. Added some of mine here and there. Description: Below is Quincey's summary. The -r and -t changes were changed to "-D r" and "-D t" as they are of the debug purposes. Need to save option letters for hundreds of future features. The nofill for chunk storage is not supported since v1.4 does not have the feature. - Added option (-r) to display the throughput when doing I/O on just the dataset data. This is somewhat redundant for the posix I/O functions and MPI-I/O, but it's useful for HDF5. - Added option (-t) to display the times along with the throughputs. - Added options (-a <size> and -T <size>) to align objects in the HDF5 file. These are ignored for posix and MPI-I/O benchmarks. - Added option (-c) to create the HDF5 datasets using chunked storage. The chunks are created with the same size as the buffer size used for I/O, so all I/O to the dataset is chunk-aligned. - Changed code to allow 0-sized datasets to be created. This is useful when measuring the overhead for creating lots of datasets in HDF5. - Cleaned up code to eliminate warnings and modularize things better. Platforms tested: modi4 (pp)
* [svn-r5450] Description:Albert Cheng2002-05-213-56/+56
| | | | | | | | | | | | | | | | | The term RAWIO was confusing (lacking a better term). It was intended to represent the "raw" way of doing I/O such that an application may use the open/read/write interface (actually Posix) or the parallel file system's native API (e.g. gpfs_open). It was too confusing to mean multiple things. Solution: Split the RAW IO into two different IO API, POSIX and NATIVE. Posix is a standard that some applications that have used it for the serial version, may want to continue using it in the parallel environment. Changed the output and variable/macro/what-not names from RAWxxx to POSIXxxx. No algorithm changes. Platforms tested: modi4(pp), eirene(serial)
* [svn-r5449] Purpose:Albert Cheng2002-05-211-7/+3
| | | | | | | | | | Code Cleanup Description: Compilers moaned about those unused mpi_err variables. Solution: Removed them for now. Will make it cleaner later. Platforms tested: modi4(pp), eirene.

* [svn-r5432] Purpose:Quincey Koziol2002-05-171-2/+6
| | | | | | | | | | | | | | | | | | Document Bug fix/Code improvement below: 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.

| | | | | | | | | | feature Description: Added a global MPI_Info object to be used by all applicable IO API (MPI-IO and PHDF5). Added a function to set up the info object according to $HDF5_MPI_INFO if set. Platforms tested: LLNL Blue/frost
* [svn-r5423] Purpose:Albert Cheng2002-05-151-24/+1
| | | | | | | Removed some local macro definition, instead use the macros defined by the hdf5 library configure. Platforms tested: LLNL blue
* [svn-r5421] Description:Albert Cheng2002-05-142-2/+2
| | | | | | | Corrected typos in the FUNC_ENTER macros of H5FD_sec2_flush and H5FD_log_flush. Platforms tested: modi4 (just tested it compiled fine.)
* [svn-r5420] Purpose:Quincey Koziol2002-05-141-19/+32
| | | | | | | | | | | | | | | | Code cleanup/Performance enhancement Description: The code to extend the file size in H5FD_mpio_flush is getting run even when the file size doesn't change. Also, it's sort of sidestepping MPI-I/O when extending the file, instead of using MPI-I/O features to set the file's size Solution: Only extend the file's size when the allocated size has increased. Also use MPI_File_set_size() to change the file's size. (Including barrier). Platforms tested: IRIX64 6.5 (modi4)

* [svn-r5416] Purpose:Quincey Koziol2002-05-141-0/+8
| | | | | | | | | | | | | | | Bug Fix Description: When H5Freopen is called, the file to reopen's 'intent' (read/write permissions, etc) is not being copied to the new file's 'intent' information. Solution: Copy it. :-) Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5413] Purpose:Quincey Koziol2002-05-141-12/+49
| | | | | | | | | | | | | | | | Bug fix Description: Calling MPI_Get_count needs to be done with the same MPI type as was used for the transfer and we are always using MPI_BYTE, even when a different MPI type was used for the transfer. Solution: Only query MPI_Get_count with MPI_BYTE when we really used MPI_BYTE for the transfer. Wait for later to query MPI_Get_count with other MPI types. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5411] Purpose:Quincey Koziol2002-05-133-2/+49
| | | | | | | | | | | | | | | Performance enhancement Description: Doing an MPI_File_sync() just before a file is closed causing a large performance loss. Solution: Add flag to MPI file driver to avoid performance the MPI_File_sync() when the flag is set before a call to H5F_flush(). Platforms tested: IRIX64 6.5 (modi4)

* [svn-r5405] Description:Albert Cheng2002-05-131-1/+0
| | | | | | | Dumb bug fix. Forgot a debug printing statement. Removed it. Platforms tested: Burrwhite (linux 2.4) parallel.
* [svn-r5402] Purpose:Albert Cheng2002-05-133-26/+35
| | | | | | | | | | | | | | | | | | Bug fix Description: Was not able to handle data size (file size) larger than 32bits. Was using long, which is only 4 bytes big in SP, thus overflowing into negative when trying to address 2GB or larger. Solution: Changed those variables involved in file size/offset calculation to type off_t. (If a certain system/compiler has off_t defined as 4 bytes, it can't write to file size larger than 2GB anyway.) Note that the lseek of SP with -D_LARGE_FILE still fails for offset larger than 2GB (works for 2GB). That has to be fixed soon. Platforms tested: LLNL blue/frost.
* [svn-r5400] Elena Pourmal2002-05-131-20/+0
| | | | | | | | | Purpose: Code clean-up Description: Removed unused HAVE_XXXX macros from the H5f90i.h file. Platforms tested: HP-UX 11.00 (kelgia) and IRIX64-6.5 (modi4)

| | | | | | | Doc oversight Description: Added my initials and the date to the note I just added.
* [svn-r5391] Purpose:Quincey Koziol2002-05-106-99/+12
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: The parallel I/O file driver is optimized to only write metadata with one process (and broadcast the results to the other processes). This is currently enabled by a separate call to H5FD_mpio_tas_allsame() before each metadata write to the file. This can easily lead to problems where the prelude function call is omitted before the actual write code or, in a threaded environment, lead to race condititions where the value set is reset before being used. Solution: Since we only want to write metadata from one process, key off of the 'type' parameter (which has information about whether the data being written it metadata or raw data) to H5FD_mpio_write() as the method for determining whether to only write from one process or not. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5388] Purpose:Quincey Koziol2002-05-101-0/+3
| | | | Update release notes about rotating metadata writes.
* [svn-r5387] Purpose:Quincey Koziol2002-05-101-4/+21
| | | | | | | | | | | | | | | New Feature Description: Currently, only process 0 writes metadata to disk, leading to a potential performance bottleneck as the other processors wait for it to catch up. Solution: Rotate the metadata responsibilities among all processes, speading out the work. Platforms tested: IRIX64 6.5 (modi4)

* [svn-r5380] Purpose:Albert Cheng2002-05-091-5/+3
| | | | | | | | | | | | Bug fix Description: IBM SP was complaining some file not closed when MPI_Finalize is called. It turned out I duplicated the MPI_File_open when I added the code to print MPI_error_string. That was dumb. Solution: Removed the extra MPI_File_open. Platforms tested: IBM SP Blue.
