* [svn-r5720] Purpose:Quincey Koziol2002-06-273-93/+176
| | | | | | | | | | New Feature Description: Added support for collective I/O with MPI and HDF5 access methods. Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5718] Purpose:Quincey Koziol2002-06-273-204/+177
| | | | | | | | | | | | New Feature Description: Added interleaved block pattern to MPI and HDF5 access methods. Also, changed the blocks to just use the same size as the regular blocks for I/O, instead of a separate block size. Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5716] Description:Albert Cheng2002-06-271-1/+1
| | | | | | Fixed a typo in LT_LINK_EXE=... line. Platforms tested: modi4 (pp)
* [svn-r5710] Purpose:Bill Wendling2002-06-252-13/+19
| | | | | | | | | Bug Fix Description: Was nulling out the RUNPARALLEL and other macros which shouldn't be nulled out. Solution: Removed the code which does the nulling out of those macros.
* [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-r5701] Purpose:Bill Wendling2002-06-251-24/+24
| | | | | | | | | | | | Bug Fix Description: Making of the programs when using the --srcdir option didn't work. It couldn't find the files to compile. Solution: Specified where the files are by prepending the $(srcdir) macro to them. Platforms tested: Linux
* [svn-r5696] Purpose:Quincey Koziol2002-06-251-2/+2
| | | | Update FreeBSD release info.
* [svn-r5692] Purpose:Bill Wendling2002-06-241-27/+35
| | | | | | | | | | | | | | Bug Fix Description: Ported the bug fix for h5cc failing on platforms from the 1.4 branch to 1.5 branch. In a nutshell, when we ran "make check" in the examples directory, libtool would get in the way trying to compile things to .lo for us. but we didn't want libtool to do this. Solution: Made it so that make check will compile only the .c files to executables without the intervening .lo stage... Platforms tested: Linux (Dangermouse and Platinum)
* [svn-r5690] Purpose:Quincey Koziol2002-06-242-29/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: When parallel I/O is used, the MPI-I/O VFL driver uses a "lazy" model to call MPI_File_set_view() in order to reduce the number of calls to this function. However, this is unsafe, because if a collective I/O which uses MPI derived types (and thus uses MPI_File_set_view()) is immediately followed by an independent I/O, the code will attempt to call MPI_File_set_view() in order to switch back to the default view of the file. MPI_File_set_view() is a collective call however, and this causes the application to hang. Solution: Removed "lazy" MPI_File_set_view() code, instead set the file view when it is needed (with MPI derived types) and immediately set the file view back to the default view before leaving the I/O routine. Platforms tested: IRIX64 6.5 (modi4) w/parallel. Also, tested with the latest development and release code for the SAF library, which now works correctly with this change. (Although the release branch of the SAF library seems to have a bug, this 1.4.4 release candidate code gets as far as the version the SAF library is released on top of (1.4.2-patch1, I believe)).
* [svn-r5686] Purpose:Albert Cheng2002-06-201-9/+16
| | | | | | sync with v1.4 of usage messages. Platforms tested: eirene pp.
* [svn-r5680] Purpose:Quincey Koziol2002-06-195-37/+104
| | | | | | | | | | | | | | | | | | | | 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-r5679] Purpose:Quincey Koziol2002-06-192-6/+12
| | | | | | | | | | | Code cleanup Description: Changed ifdef name from "VERBOSE" to "BARRIER_CHECKS", to better describe what it affects. Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5677] Purpose:Quincey Koziol2002-06-1910-71/+52
| | | | | | | | | | | Code improvement Description: Some small code cleanups and took out the code the was turning off the metadata cache for parallel I/O (!) Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5674] Purpose:Quincey Koziol2002-06-1916-96/+93
| | | | | | | | | | Code cleanup Description: Removed more compiler warnings, etc. Platforms tested: Linux 2.2.x (eirene) w/parallel
* [svn-r5670] Purpose:Quincey Koziol2002-06-193-26/+0
| | | | | | | | | | | Code cleanup Description: Remove "COALESCE_READS" ifdefs, which were brought in by the DPSS VFL driver and are no longer used. Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5667] Purpose:Quincey Koziol2002-06-1918-82/+80
| | | | | | | | | | Code cleanup Description: Turn on more warnings in the IRIX builds and clean them up. Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5662] Purpose:Quincey Koziol2002-06-185-221/+32
| | | | | | | | | | | | | | | | | 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-r5660] Purpose:Quincey Koziol2002-06-184-130/+242
| | | | | | | | | | | | 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-r5659] Purpose:Bill Wendling2002-06-171-5/+40
| | | | | | | | | | Feature Add Description: Allow you to specify the percentage you'd like a random buffer to be compressible. It can go from 0% (non-compressible) to 100% (completely compressible). Platforms tested: FreeBSD

* [svn-r5656] Purpose:Bill Wendling2002-06-171-6/+38
| | | | | | | | | Feature Add Description: Use the /dev/urandom device for random data if it's available. (That is stat() doesn't return a -1 when ran on it). Use random() otherwise. Platforms tested: Linux, FreeBSD
* [svn-r5654] Purpose:Bill Wendling2002-06-171-9/+39
| | | | | | | | | Feature Add Description: Added a feature that outputs the total time spent compressing all of the blocks of data. Platforms tested: Linux
* [svn-r5652] Purpose:Quincey Koziol2002-06-175-36/+112
| | | | | | | | | | | | 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 Koziol2002-06-173-29/+68
| | | | | | | | | | | | 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-r5645] Purpose:Bill Wendling2002-06-161-1/+1
| | | | | | | | | | | | | | | Possible Bug Fix Description: There seems to be a problem with the h5cc script picking up old header files. This may have something to do with the CPPFLAGS macro being set to some nefarious thing and the compiler looking in those directories for the header files instead of the one where HDF5 is actually installed. Solution: Put the -I$includedir first. Platforms tested: None...This is really triggered by the nightly tests. I'm kind of hoping that this will fix things...
* [svn-r5636] Purpose:Quincey Koziol2002-06-142-2/+5
| | | | | | | | | | Default change Description: Enable the use of MPI types for collective I/O by default. Platforms tested: Linux 2.2.x (eirene) w/parallel

| | | | | | | | | | | | | | | | Purpose: [is this a bug fix? feature? ...] Description: [describe the bug, or describe the new feature, etc] Solution: [details about the changes, algorithm, etc...] [Please as detail as you can since your own explanation is better than others guessing it from the code.] Platforms tested: [machines you have tested the changed version. This is absolute important. Test it out on at least two or three different platforms such as Big-endian-32bit (SUN/IRIX), little-endian-32(LINUX) and 64-bit (IRIX64/UNICOS/DEC-ALPHA) would be good.]
* [svn-r5627] Purpose:Albert Cheng2002-06-132-1/+4
| | | | | | | | | | | | | | | | | Bug fix Description: Old setup put $(srcdir)/h5redeploy in the install list but this same list is used for clean too, thus the file is removed from source. That is bad. Solution: Set it to use a cp to do it. Need to change the source version name to something else because for one, it is confusing to use the same name. For another, if the build is done in place (i.e., not using --srcdir), the source file is removed, again. So, renamed it with the .in suffix. Who knows, it may take more processing than just cp when more features are added to it. Platforms tested: Eirene

| | | | | | | | | New tool Description: This updates compiler tools (e.g., h5cc) with new directory where the HDF5 software has been installed. Platforms tested: modi4.
* [svn-r5605] Purpose:Quincey Koziol2002-06-124-11/+16
| | | | | | | | | | Code cleanup Description: Clean up some compiler warnings... Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5603] Purpose:Quincey Koziol2002-06-123-16/+44
| | | | | | | | | | | | | | | | Bug fix Description: I/O on "Regular" hyperslab selections could fail to transfer correctly if the number of elements in the selection's row did now fit "evenly" into the buffer being used for the transfer. Solution: Correct the calculation of the block & count offsets within the optimized "regular" hyperslab routines. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5601] Purpose:Bill Wendling2002-06-121-1/+15
| | | | | | | | More Output Description: Added some more output, including the compression ratio. Platforms tested: Linux, FreeBSD
* [svn-r5597] Purpose:Quincey Koziol2002-06-111-1/+9
| | | | | | | | | | | | | | Code cleanup Description: The test for inserting a compound datatype into itself (which should fail) is issuing warnings about this failure. Solution: Turn the warnings off during this test. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5596] Elena Pourmal2002-06-111-0/+84
| | | | | | | | | | | Purpose: Bug #774 fix Description: Added a test for the H5Tenum_nameof and H5Tenum_valueof functions. Values that do not exists in the enumeration type are supplied to the functions; functions should fail instead of succeeding. Platforms tested: Solaris 2.7 and Linux 2.2.18
* [svn-r5595] Elena Pourmal2002-06-111-7/+17
| | | | | | | | | | | | | | | Purpose: Bug #774 fix Description: H5Tenum_valueof and H5Tenum_nameof functions did not fail when non-existing name or non-existing value were supplied. This happened because binary search algorithm did not check if value or name found during the search were equal to the supplied one. Solution: Added an appropriate check condition. Platforms tested: Solaris 2.7 and Linux 2.2.18
* [svn-r5591] Purpose:Bill Wendling2002-06-111-1/+4
| | | | | | | | Update Description: Explained that, if the user uses the "make install prefix=NEW_DIR" option, they'll need to modify the installed h5cc file to reflect the change.
* [svn-r5590] Purpose:Bill Wendling2002-06-111-1/+1
| | | | | | | | | | Bug Fix Description: The test for compression needed to be reversed. Solution: Instead of "!(defined...) used just "(defined..." Platforms tested: Modi4
* [svn-r5589] Purpose:Quincey Koziol2002-06-111-2/+2
| | | | | | | | | | | | | | Bug fix. Description: H5P_get was reading a 'hsize_t' field into a 'size_t' variable, causing problems on the HP's and Windows. Solution: Changed the variable to be an hsize_t Platforms tested: HP/UX 11.0 (kelgia)
* [svn-r5587] Purpose:Bill Wendling2002-06-111-2/+2
| | | | | | | | | Bug Fix take 2 Description: The check for ZLIB_H wasn't sufficient. Solution: Used the test for compression stuff that was in the test/dsets.c file.
* [svn-r5586] Purpose:Quincey Koziol2002-06-116-12/+188
| | | | | | | | | | | | | | | | Bug Fix Description: H5Dcreate and H5Tcommit allow "empty" compound and enumerated types (i.e. ones with no members) to be stored in the file, but this causes an assertion failure and is somewhat vapid. Solution: Check the datatype "makes sense" before using it for H5Dcreate and H5Tcommit. Platforms tested: FreeBSD 4.5 (sleipnir)
