* [svn-r12555] 1. Erased a strange character added to this codeMuQun Yang2006-08-091-8/+35

* [svn-r12553] This check-in includes the following part of parallel ↵MuQun Yang2006-08-098-226/+544
| | | | | | | | | | | | | | | optimization codes: 1. Provide another option for users to do independent IO with MPI file setview(collectively) 2. With the request of collective IO from users, using Independent IO with MPI file setview if we find collective IO is not good for the applications for IO per chunk(multi-chunk IO) case. Previously we used pure independent IO and that actually performed small IO(IO each row) for this case. The recent performance study suggested the independent IO with file setview can acheieve significantly better performance than collective IO when not many processes participate in the IO. 3. For applications that explicitly choose to do collective IO per chunk case, the library won't do any optimization(gather/broadcast) operations. The library simply passes the collective IO request to MPI-IO. Tested at copper, kagiso, heping, mir and tungsten(cmpi and mpich) Kagiso is using LAM, t_mpi test was broken even. The cchunk10 test failed at heping and mir. I suspected it was an MPICH problem. Will investigate later. Everything passed at copper. at tungsten: the old cmpi bug(failed at esetw) is still there. Other tests passed. Some sequential fheap tests failed at kagiso.

| | | | | | | | | | | More tweaks on fractal heap statistics, to better separate information about managed objects from information about "huge" objects. Also, clean up some compiler warnings, etc. on 64-bit platforms & Windows. Platforms tested: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago)
* [svn-r12551] Description:Quincey Koziol2006-08-078-95/+86
| | | | | | | | | | | Refactor fields in heap header to clean out information from dropped features and also group related fields together more nicely. Add fields to heap header for storing information about "huge" objects. Platforms tested: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago)
* [svn-r12550] Description:Quincey Koziol2006-08-074-39/+95
| | | | | | | | | | | Refactor fractal heap IDs to include "flag byte" as part of the ID. This byte will be used for the heap ID format version as well as flags to indicate whether the heap object is a "tiny"/normal/"huge" object (with storage mechanisms optimized for each type of object). Platforms tested: Linux/32 2.4 (chicago) Too minor to require h5committest

* [svn-r12528] Added User-Defined links to the library.James Laird2006-08-0245-1302/+3747
| | | | | | | | | | | | | | Users can create external links using H5L_create_external(). These links point to an object in another HDF5 file. Users can alter the behavior of external links or create new kinds of links by registering callbacks using the H5L interface. Added tests, tools support, etc. Also a number of other, minor changes have been made (some restructuring of the H5L interface, for instance). Additional documentation and examples are forthcoming.

| | | | | | | | | | | Refactored free space manager to use metadata cache for serialized free space sections. This speeds up the fractal heap test considerably... Tested: FreeBSD 4.11 (sleipnir) Linux 2.4/32 (chicago) Linux 2.4/64 (mir) Mac OS X (amazon)
* [svn-r12519] Fixed "make check-vfd"James Laird2006-07-311-2/+3
| | | | | | | | | | "make check-vfd" will now run all tests in the test directory with different file drivers (at least, all of those tests that use the testing framework's FAPL). Tests that fail will be skipped. This is not a perfect fix, but is better than nothing. Along with this change, check-vfd should be added to the Daily Tests.
* [svn-r12517] Description:Quincey Koziol2006-07-3111-351/+760
| | | | | | | | | | | | | | | Fix the last scattered bunch of problems with the object deletion code, which appears to be completely working now (for objects that are stored within heap blocks - standalone objects aren't implemented yet). Also, re-work the regression test to speed up some of the existing tests and add in 100-200 more combinations of tests - overall, its probably even slower than it was... :-/ Tested: FreeBSD 4.11 (sleipnir) Linux 2.4 (chicago) Mac OS X (amazon)

* [svn-r12462] Committed a variety of metadata cache related changes:John Mainzer2006-07-1312-182/+1534
| | | | | | | | | | | | | | | | | | | | | | 1) Added trace file support to the metadata cache. This allows capture of all metadata cache calls in trace files for purposes of optimization and debuging. 2) Added an expunge entry function. This allows an entry to be deleteded from the cache without writing it to disk even if it is dirty. 3) Added a function call to resize pinned entries. 4) Added code to deal with entries that are dirty on load. This is needed in support of a bug fix which can alter object headers on load to repair files. 5) Added progress reporting code to the "MDC API smoke check" test in cache_api.c. To enable the progress reporting, set report_progress to TRUE in mdc_api_call_smoke_check(). Tested with h5committest, and a parallel test on phoenix (dual athelon linux box).

| | | | | | | | | | | | | | | | | | | | | | Feature Description: Revised Link APIs. Solution: New link APIs use H5L* H5*create_expand do not create links to the objects created; this must be done manually with H5Llink. Added APIs to link an object given its ID (H5Llink), to copy links (H5Lcopy), and changed creation APIs (H5Lcreate_hard and H5Lcreate_soft) and query API (H5Lget_linkinfo instead of H5Gget_objinfo). All old APIs are still supported in H5Gdeprec.c . Platforms tested: sol, mir, copper Misc. update: Forgot to update MANIFEST and release docs. Will do after checkin.

* [svn-r12435] Purpose: Bug fixRaymond Lu2006-06-234-6/+19
| | | | | | | | | | | | Description: Mac OS 10.4 on PowerPC chip has some errors to convert (unsigned) long long to long double. When the bit sequences are 0x003ff..., 0x007fff..., 0x00ffff..., 0x01ffff..., 0x7fffff..., the converted values are twice as big as they should be. Solution: Detect the error in configure and disable the compiler conversion and test case. Platforms tested: h5committest, Mac OS 10.4, and fuss.
* [svn-r12431] Purpose:James Laird2006-06-211-15/+5
| | | | | | | | | | | | | | Configuration feature Description: 'make install' now tests both static and shared libraries if both are installed.

Platforms tested: mir (Makefile change only)
* [svn-r12425] Purpose: Bug fixRaymond Lu2006-06-202-6/+11
| | | | | | | | | | | | | | | Description: Data conversion from long double to (unsigned) long long returns some incorrect values on Mac OS 10.4 and SGI IRIX64 6.5. The conversions start to go wrong when the long double is 20041683600089727.779961 (0x4351ccf385ebc8a0bfcc2a...). If adjusting the values higher by assigning 0x...c8a0cf... or 0x...c8a0df..., the converted values go wild. Solution: Detect this error in configure.in and disable compiler conversions from long double to (unsigned) long long for Mac OS 10.4 and IRIX64 6.5. Platforms tested: h5committest, Mac OS 10.4, and IRIX64 6.5.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some collective chunk IO macro names are confusing, change them to more meaningful names. Description: H5Pset_dxpl_mpio_chunk_opt will set a flag so that the library can do one linked IO or multi-chunk IO with collective in chunking storage directly. That is, the library won't do analyses to determine this. The flags for the enum type we used before are: H5FD_MPIO_OPT_ONE_IO H5FD_MPIO_OPT_MULTI_IO They are not good names because of the following two reasons: 1. It doesn't reflect chunking storage 2. OPT is kind of redundant and misleading, Solution: We change the names to H5FD_MPIO_CHUNK_ONE_IO H5FD_MPIO_CHUNK_MULTI_IO Platforms tested: Since only macro names are changed, no need to test with h5committest. heping(mpich 1.2.6) Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Check in potential fix to unreproduceable bug in t_cache observed on Cobalt 2) Check in code supporting added pinned entry features in the metadata cache. Description: 1) Elena encountered a bug in t_cache when running on Cobalt. On investigation I found a potential race condition in t_cache that could explain her observation. 2) Quincey requested additions to the metadata cache allowing renaming of pinned entryies, and marking of pinned or protected entries as dirty. Solution: 1) Modified t_cache.c to prevent the potential race condition. Elena was unable to reproduce the bug on Cobalt, so we don't know if my fix actually addressed the problem. 2) Added code supporting the requested functions. The changes were relatively trivial, but required substantial new test code. Platforms tested: h5committest, serial test on heping, parallel test on phoenix. Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix. Description: The ${TR}, though avoid the error, is inconvenient. It is needed because configure.in use the char range in the style of 'a-z'. The other style of '[a-z]' is more commonly accepted by all tr but autoconf tends to strip away [], making the syntax rather clumsy. Solution: Learned from autoconf that it avoids the use of character range by just spell all the letters out. Changed our tr commands to use those variables defined by autoconf. Also removed the definition of ${TR} since it will cause inconsistancy when autoconf also use plain 'tr' in its generated code. The Makefile.in are changed because the elimination of ${TR} from configure triggered its removal from all Makefil.in. That is okay because ${TR} is not used at all in Makefile. Platforms tested: h5committested. (sol failed to connected). also tested in shanti using both /usr/ucb/tr and /bin/tr (the bad one before.) Misc. update: Updated both INSTALL and RELEASE files.

| | | | | | | | | | | | | | | | | | Bug fix. Description: Some machines (e.g., HPUX) will have off64_t defined but no support for stat64 unless certain LargeFile macro is turned on. This caused the last fix on H5private not quite right which caused compiling failures. Solution: Added stat64 and fstat64 tests and then will use them only if they are supported. Platforms tested: Tested on kelgia, copper and heping (pll). (Compiling alright but tests for kelgia and heping are not done. expect no problems.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug fix for collective chunk IO Description: Several options have been provided inside HDF5 library for obtaining chunk addresses when doing collective chunk IO. One option is to obtain chunk addresses for one process and broadcast to other processes. This option needs all processes to participate. If using link-chunked IO without any optimizations, sometimes this is not true due to the random initialization for one variable at mpich 1.2.7. This is a bug inside the collective chunk IO code. Solution: 1.Initalize all the variables to some safe numbers, 2. Avoid using MPI broadcast to obtain the chunk address if possible until more performance studies have been done. 3. Seems okay to obtain chunk addresses individually for each processor. This option may cover most cases. Platforms tested: h5committest(copper is not usable) NCSA teragrid (mpich 1.2.5) mir 64-bit linux (mpich 1.2.6) Misc. update:
* [svn-r12342] Purpose:Albert Cheng2006-05-102-29/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | bug fix. Description: Previous H5private.h would attempt to use the off64_t/stat64/etc by checking just sizeof __INT64 being 8. This caused errors in some machines like alpha cluster which is a 64bit machine. Its compiler supports the type __int64 but it does not support off64_t since its off_t is already 64bits big. The above code casued the compiler to complain about the unknown off64_t and such. Solution: H5private.h: Changed the code to use the pseudo standard of off64_t/stat64/etc only if sizeof(off_t) is not 64 bits AND sizeof(off64_t) exists and is 64 bits. This assumes if off64_t is defined, all those stat64, fstat64, etc are supported too. configure.in: configure: Added the testing of sizeof(off64_t) to support the above solution. Platforms tested: h5committested. Also tested at LANL QSC.
