* [svn-r5802] Purpose:Quincey Koziol2002-07-151-0/+10
| | | | | | | | Update docs Description: Note --with-dmalloc addition to configure flags and new MPI-posix VFL driver.
* [svn-r5800] Purpose:Quincey Koziol2002-07-152-0/+16
| | | | | | | | | | New feature. Description: Added MPI-posix VFL driver support. Platforms tested: FreeBSD 4.6 (sleipnir) w/parallel & IRIX64 6.5 (modi4) w/parallel
* [svn-r5799] Purpose:Quincey Koziol2002-07-1514-167/+1427
| | | | | | | | | | | | 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-r5798] Purpose:Quincey Koziol2002-07-153-9/+53
| | | | | | | | | | New feature. Description: Added MPI-posix VFL driver support. Platforms tested: FreeBSD 4.6 (sleipnir) w/parallel & IRIX64 6.5 (modi4) w/parallel
* [svn-r5795] Purpose:Quincey Koziol2002-07-154-5/+69
| | | | | | | | | | | New feature Description: Changed parallel I/O tests to use test script instead of just running testphdf5 executable. This allows the MPI-posix driver to be tested easily. Platforms tested: FreeBSD 4.6 (sleipnir) w/parallel and IRIX64 6.5 (modi4) w/parallel
* [svn-r5793] Purpose:Quincey Koziol2002-07-152-19/+37
| | | | | | | | | | | | Code cleanup Description: Changed a few direct calls to posix functions to use proper wrapper macros. Also, changed method of extending file to use ftruncate(). Platforms tested: FreeBSD 4.6 (sleipnir) && IRIX64 6.5 (modi4)
* [svn-r5791] Purpose:Quincey Koziol2002-07-151-1/+1

| | | | | | | | | | Code update Description: Re-arrange to disable free-list code in a more transparent way. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5784] Purpose:Quincey Koziol2002-07-121-91/+100
| | | | | | | | | | | | | | | Bug fix. Description: "strong" file closing feature was re-using free'd memory for objects which were still open in the file. Solution: Used the "dmalloc" tools to determine where the memory was being re-used and re-arranged the code to avoid these cases. Platforms tested: FreeBSD 4.6 (sleipnir)
* [svn-r5783] Purpose:Quincey Koziol2002-07-122-2/+6

* [svn-r5772] Frank Baker2002-07-051-3/+14
| | | | | | | | | | | | | | | Purpose: Add copyright and change "HDF5 Tutorial" link. Description: Added copyright statement and link. Changed the "Tutorial" link to point to the copy on the HDF5 website. Since the Tutorial is not maintained in CVS, the distributed version of the Tutorial is being unlinked and removed from the set of distributed files. It is hoped that we can begin maintaining the Tutorial under CVS prior to Release 1.6 and resume its distribution. Platforms tested: IE 5

| | | | | | | | | | | | | | | Bug fix. Description: 1-D non-contiguous hyperslabs were erroneously being detected as contiguous and were causing incorrect behavior for parallel I/O benchmark (and parallel programs in general). Solution: Modified algorithm to handle 1-D case correctly. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5736] Raymond Lu2002-07-011-1/+1
| | | | | | | | | | | | Purpose: Bug fix. Description: This test fails on TRUE64 system because a compound variable(fill_ctype in test_rdwr) wasn't initialized. Solution: Initialize to zero. Platforms tested: Pittsburg's True64(lemieux) system.
* [svn-r5729] Purpose:Albert Cheng2002-06-307-23/+94
| | | | | | | | Bring in sync with v1.4 versions that have copyright statements added. Platforms tested: eirene(pp). Only one machine tested because all changes are merely comments.

* [svn-r5727] Purpose:Albert Cheng2002-06-297-13/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | | Porting to AIX 5.x Description: These have been tested out in v1.4. Folding them in here. aclocal.m4: Snow's names were not included in the special hack. Added its names in. Removed the trailing * in pacific.llnl.gov too. configure.in: fortran/configure.in: Added a case to group all AIX 5.* versions as aix5.x. This allows them to share one common config/*aix5.x file. configure: fortran/configure: Derived from configure.in (done in eirene). config/powerpc-ibm-aix4.x: Added a comment explaining why not to cache sizeof size_t and off_t fortran/config/powerpc-ibm-aix4.x: Turned of cache of sizeof size_t and off_t because they are depedent on compiler options. config/powerpc-ibm-aix5.x: fortran/config/powerpc-ibm-aix5.x: New config file for AIX 5.X Platforms tests: LLNL Blue, Frost, Snow, both serial and 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
