* [svn-r6231] Purpose:Albert Cheng2003-01-032-4/+151
| | | | | | | | | | | | | | | new feature Description: Added MPICH/MPE instrumentation support. All source code are bracketed by the macro H5_HAVE_MPE. Use "--enable-mpe" to configure it in. Currently only worked in Eirene because the MPE library is not installed in all machines yet. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}? Yep. Other platforms/configurations tested? --enable-mpe feature tested in Eirene.
* [svn-r6229] Purpose:Albert Cheng2003-01-031-1/+2
| | | | | | | | | | | Minor fix Description: By mistake, the MPI_Error handling macros were inserted outside the overall macro bracket. Moved them back inside the bracket. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)}? Yep.
* [svn-r6228] Description:Albert Cheng2003-01-031-3/+0
| | | | | | | | When I removed the option (--enable-parallel=mpich), which did not work, I failed to run autoheader to update this file. I am checking in the updated version now. Platforms tested: No need to test since it just removed a #undefine and comments.
* [svn-r6225] Purpose:Albert Cheng2003-01-021-3/+7
| | | | | | | | | | Bug fix Description: SGI shell treats $0 as function name if used in a function. Set the name here to avoid that ambiguity and better style too. Platforms tested: Just in modi4 and burrwhite since it is a shell script and the change is machine independent.
* [svn-r6223] Purpose:Binh-Minh Ribler2002-12-222-8/+8
| | | | | | | | | | | | | | | | | | | | | | Bug fix - informed by Kent Description: Some identifiers were flagged as unresolved symbols when building with c++ on Windows. The reason is the name of these identifiers were changed by the c++ compiler, also called name mangling. Solution: Moved #ifdef __cplusplus extern "C" { #endif to include the offending identifiers so the c++ compiler will take them as is. Platforms: SunOS 5.7 (arabica) Linux 6.2 (eirene) Windows 2000

* [svn-r6220] Purpose:Bill Wendling2002-12-194-156/+299
| | | | | | | | | | Update Description: A few generic changes to the FPHDF5 code. Some error messages reworked a bit. Cleaning up in case of failure improved in some cases. Added another field to the synchronization messages... Platforms tested: Linux
* [svn-r6219] Purpose:Bill Wendling2002-12-191-1/+0
| | | | | | | | | Update Description: Removed the EFL field from the FPHDF5 structure as the property list already has this info. Platforms tested: Linux
* [svn-r6218] Purpose:Bill Wendling2002-12-191-47/+17
| | | | | | | | | | Bug Fix Description: Was encoding a value as DTYPE instead of MTIME, which would cause a couple of errors. Also, got rid of the EFL field as it's encoded in the PLIST already... Platforms tested: Linux...Modest test, FPHDF5 not fully implemented just yet.
* [svn-r6217] Elena Pourmal2002-12-191-1/+89

* [svn-r6205] MuQun Yang2002-12-131-0/+0
| | | | | | | | | | | | | Purpose: update windows project file Description: Solution: Platforms tested: windows 2000(not affect other platforms) Misc. update: Update MANIFEST if you add or remove any file. Update release_docs/RELEASE for bug fixes, new features, etc. Update applicable document files too.
* [svn-r6204] MuQun Yang2002-12-131-32/+62
| | | | | | | | | | | | | | | | | Purpose: bug fix Description: Need to use HDopen, HDread for windows support. off_t in windows is 32-bit; however, windows can support 64-bit file. So we have to change off_t to int64 in order that >4G file can be supported. Solution: See above Platforms tested: linux2.2.18smp, windows 2000 Misc. update: Update MANIFEST if you add or remove any file. Update release_docs/RELEASE for bug fixes, new features, etc. Update applicable document files too.
* [svn-r6203] MuQun Yang2002-12-131-5/+6
| | | | | | | | | | | | | | | | Purpose: bug fixed for windows Description: windows fopen functions by default opens a text mode file. It will fail for HDF5 file. So to use HDopen HDread HDclose for test. Solution: Change from fopen, fread, fclose to HDopen, HDread, HDclose. Platforms tested: linux2.2.18smp, windows 2000 Misc. update: Update MANIFEST if you add or remove any file.

| | | | | | | | | | | | | | | | Purpose: Fix bugs for windows platform. Description: 1. Update HDlseek for windows 2. Update H5Otime.c for normal time(non-daylight time) 3. Add H5_DLL in front of two functions so that windows DLL can work. Solution: Platforms tested: windows 2000, eirene(since most updates have WIN32 around it, not need to test other platforms) Misc. update: Update MANIFEST if you add or remove any file. Update release_docs/RELEASE for bug fixes, new features, etc. Update applicable document files too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: New Feature; Optimization; Clean-up (Merged from 1.4 branch) Description: There is no symbolic constant to pass to functions that take an optional object ID for when the caller wants to indicate no object ID. In the past the caller always passed a negative integer. GPFS performs poorly. The h5ls tool decides whether to list the file name in the output based on a compile-time choice, which isn't always optimal at run time. Solution: Added a symbolic constant H5I_INVALID_HID. Added code to tell the mmfsd of GPFS to forego byte range token prefetching. h5ls decides whether to print the file name at runtime based on the number of objects being listed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Feature; Optimization Description: Clients pass `-1' or make their own #define for HDF5 functions that take an optional object ID. Blue's GPFS is slow for typical SAF restart dumps. Solution: Added a #define for H5I_INVALID_HID Added GPFS-specific code to H5FDmpiposix.c that tells mmfsd to forego byte range token prefetching. This code can be compiled into the library by defining USE_GPFS_HINTS. The plan is to either generalize this so it's detected during configure and turned on/off at runtime, or to move it up into DSL/SAF with the new HDF5 functions to that return the low-level file handle. Platforms tested: SuSE Linux (arborea), gcc and mpich-1.2.4 SunOS (baldric), gcc 2002-09-05 12:24:28 Robb Matzke <matzke@arborea.spizella.com> *: Added #define for H5I_INVALID_HID. An invalid object handle is actually any integer that isn't currently in use as a handle, and non-positive integers are never used as a handle. The #define is -1, and is mostly so that HDF5 users can pass a symbolic name instead of a negative number to functions that take optional object ID arguments.
* [svn-r6148] ./hdf5-devel/src/H5FDmpiposix.cRobb Matzke2002-12-041-10/+58
| | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Feature; Optimization Description: Clients pass `-1' or make their own #define for HDF5 functions that take an optional object ID. Blue's GPFS is slow for typical SAF restart dumps. Solution: Added a #define for H5I_INVALID_HID Added GPFS-specific code to H5FDmpiposix.c that tells mmfsd to forego byte range token prefetching. This code can be compiled into the library by defining USE_GPFS_HINTS. The plan is to either generalize this so it's detected during configure and turned on/off at runtime, or to move it up into DSL/SAF with the new HDF5 functions to that return the low-level file handle. Platforms tested: SuSE Linux (arborea), gcc and mpich-1.2.4 SunOS (baldric), gcc
