* [svn-r5536] Purpose:Quincey Koziol2002-06-0516-208/+306
| | | | | | | | | | | | | | | | | New feature. Description: Added a "small data" block allocation mechanism to the library, similar to the mechanism used for allocating metadata currently. See the RFC for more details: http://hdf.ncsa.uiuc.edu/RFC/SmallData/SmallData.html This reduces the number of I/O operations which hit the disk for my test program from 19 to 15 (i.e. from 393 to 15, overall). Platforms tested: Solaris 2.7 (arabica) w/FORTRAN and FreeBSD 4.5 (sleipnir) w/C++
* [svn-r5534] Purpose:Albert Cheng2002-06-041-18/+30
| | | | | | Updated the instructions for tflops and O2K. Platforms tested: eye balled.
* [svn-r5531] Purpose:Bill Wendling2002-06-043-91/+405
| | | | | | | | | Feature Add Description: Added support for testing only the "write" operations. Use the "-w" or "--write-only" flags for this. Platforms tested: Linux (parallel) & Modi4 (parallel)
* [svn-r5530] Purpose:Bill Wendling2002-06-0410-18/+39
| | | | | | | | | | | | | | | Code Cleanup Description: Removed some compiler warnings. Solution: In a few cases, NULL was being returned when a FAIL was supposed to be returned instead. There were some header files which needed to be included in a few of the sources. A couple of if-then statements had assignments in the conditional part. The compiler warned that they should have extra "()"s around them. Made the code check the values instead. Platforms tested: Linux (parallel) Modi4 (parallel)
* [svn-r5529] Purpose:Quincey Koziol2002-06-041-4/+36
| | | | | | | | | | | | | | | Code improvement Description: Now that the metadata accumulator is working correctly, the buffer size tends to get rather large and stay there. Solution: Put a throttle on the accumulator buffer to reduce its size back down when it isn't needed. Platforms tested: Solaris 2.7 (arabica) w/FORTRAN & FreeBSD 4.5 (sleipnir) w/C++
* [svn-r5526] Purpose:Bill Wendling2002-06-041-2/+2
| | | | | | | | | | Bug Fix Description: Still was calling the POSIX stuff "Raw". Solution: Changed name to POSIX instead of Raw... Platforms tested: Linux
* [svn-r5525] Elena Pourmal2002-06-041-0/+5
| | | | | | | | | | | | | | Purpose: Bug fix (#699), fix provided by a user, approved by Quincey Description: When a scalar dataspace was written to the file and then subsequently queried with the H5Sget_simple_extent_type function, type was reported H5S_SIMPLE instead of H5S_SCALAR. Solution: Applied a fix (see bug report 699) and modified out test program to exercise the case. Platforms tested: Solaris 2.7 and Linux 2.2.18
* [svn-r5524] Elena Pourmal2002-06-042-8/+17

* [svn-r5521] Purpose:Quincey Koziol2002-06-042-11/+39
| | | | | | | | | | | | | | | | | | | | | | | Code improvement Description: The metadata aggregation code in the library was not terribly smart about extending contiguous regions of metadata in the file and would not extend them as far as possible. This causes space in the file to be wasted, also. Solution: Be smarter about extending the space used in the file for metadata by checking whether new metadata blocks allocated in the file are at the end of the current metadata aggregation region and append them to the metadata region if so. This has the nice side benefit of reducing the number of bytes we waste in the file and reducing the size of the file by a small amount in some cases. This reduces the number of I/O operations which hit the disk for my test program from 53 to 19 (i.e. from 393 to 19, overall). Platforms tested: Solaris 2.7 (arabica) w/FORTRAN and FreeBSD 4.5 (sleipnir) w/C++
* [svn-r5519] Purpose:Quincey Koziol2002-06-042-1/+13
| | | | | | | | | | | | | | | | | | Bug Fix Description: The "dirty" flag for symbol table entries and symbol table nodes was not being cleared when they were flushed to the file, causing lots of extra metadata I/O. Solution: Reset the symbol table entry & nodes' flags when thy are flushed to disk. This reduces the number of I/O operations which hit the disk for my test program from 83 to 53 (i.e. from 393 to 53, overall). Platforms tested: Solaris 2.7 (arabica) w/FORTRAN & FreeBSD 4.5 (sleipnir) w/C++
* [svn-r5516] Purpose:Albert Cheng2002-06-041-139/+153
| | | | | | | | | | | | | | Tidy up Description: Old version showed tons of output even if MPI_Offset is too small to support multiple GB sized files and destined to fail. Output is pretty confusing. Solution: Prints the signness and size of MPI_Offset for information. Skipped tests if MPI_Offset is not big enough to support the file sizes. Platforms tested: modi4, eirene, burrwhite (all parallel).
* [svn-r5515] Purpose:Bill Wendling2002-06-031-6/+29
| | | | | | | | | | | | Bug Fix Description: There was an error in the way it was determining if there were any reads to report. Solution: Wrote a subroutine which would determine if the reads are defined in the structure before trying to print them out. Platforms tested: Linux
* [svn-r5512] Purpose:Bill Wendling2002-06-031-0/+1
| | | | | | Update Description: Added the "perform/gen_report.pl" file.
* [svn-r5511] Purpose:Bill Wendling2002-06-031-0/+262
| | | | | | | | | | | Add Report Generator Description: This is a generator for ASCII and Excel(tm)(c) reports generated by the pio_perf benchmark we run. There are instructions at the top of the file on how to run the program and the input format it expects, etc. Platforms tested: Linux
* [svn-r5510] Purpose:Quincey Koziol2002-06-032-57/+103
| | | | | | | | | | | | | | | | | | | | | | | | Code cleanup/bug fix Description: The "metadata accumulator" cache in the library (which is designed to catch small metadata writes/reads and bundle them together into larger I/O buffers) was incorrectly detecting the important case of metadata pieces being written sequentially to the file, adjoining but not overlapping. Additionally, the metadata accumulator was not being used to cache data read in from disk, only caching writes. Solution: Fix accumulator to correctly cache adjoining metadata writes and also to cache metadata read from disk. Between these two fixes, the number of I/O requests which resulted in actual reads/writes to the filesystem dropped from 393 requests to 82 for the particular test I was using. :-) Platforms tested: Solaris 2.7 (arabica) w/FORTRAN & FreeBSD 4.5 (sleipnir) w/C++
* [svn-r5508] Elena Pourmal2002-06-031-1/+1

* [svn-r5503] Purpose:Albert Cheng2002-06-012-120/+370
| | | | | | | | | Features Description: Added a few macros to print rank and size of MPI_COMM_WORLD in a unifed style. Platforms tested: modi4, eirene, burrwhite
* [svn-r5502] Purpose:Quincey Koziol2002-06-012-1/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Test Bug Fix Description: Under certain [obscure] circumstances, an object header would get paged out of the metadata cache, and when it was accessed again and brought back into the cache, and immediately had additional metadata added to it (an attribute, usually, or perhaps adding an object to a group), and needed to be extended with a continuation message, but there was no room in any existing object header chunks for the continuation message and an existing object header message needed to be moved to the new object header chunk (I told you it was obscure :-), the object header message moved to the new chunk (not the new metadata being added) would get corrupted. *whew* :-) Solution: Actually copy the "raw" object header message information of the object header message being moved to the new chunk, instead of relying on the "native" object header message information being re-encoded when the object header is flushed. This is because when an object header is paged out of the metadata cache and subsequently brought back in, the "native" information pointer in memory is reset to NULL and only the "raw" information exists. [Actually, this additional testing doesn't trigger the bug, which needs _lots_ of objects to be created and accessed, but it does execise the object header continuation code more than other tests in the library.] Platforms tested: Solaris 2.7 (arabica) & FreeBSD 4.5 (sleipnir)

* [svn-r5495] Purpose:Bill Wendling2002-05-312-4/+167
| | | | | | | | | | | | Bug Fix Description: C++ uses the "off_t" type for external files as well. I'm assuming that there's going to be a problem with 4 byte off_ts and 8 byte off_ts in the C++ code as well. I compiled everything on Linux and it worked, but I don't think we have a check for this bug in the library yet... Platforms tested: Linux
* [svn-r5492] Elena Pourmal2002-05-317-18/+16
| | | | | | | | | | | Purpose: Code clean up. Description: Many F90 compilers were not happy about character*(*) declarations. Solution: Used F90 character(len=*) declarations. Platforms tested: Solaris 2.7 and Linux 2.4
* [svn-r5491] Purpose:Bill Wendling2002-05-311-23/+74
| | | | | | | | | | | Feature Enhancement Description: We can now set the MPI_Info object to more than one key/value pairing. By setting the HDF5_MPI_INFO environment variable to a semicolon separated list of "key=value" pairs, we can set the MPI_Info variable to them. Platforms tested: Linux
* [svn-r5490] Purpose:Elena Pourmal2002-05-315-224/+739
| | | | | | | | | Code cleanup Description: While working on the "External test" failure I restructured and cleaned up some C stub code. Platforms tested: dangermouse (Linux 2.4)
* [svn-r5488] Purpose:Bill Wendling2002-05-302-4/+167
| | | | | | | | | | | | | Bug Fix Description: On Linux 2.4 kernel, we need to check for Linux LFS support. There was a failure in the Fortran code when we tried to pass a 4 byte off_t variable to a function which expected an 8 byte off_t. This is due to there being no check for the LFS support in the Fortran code. Solution: Added the check for Linux LFS support. Platforms tested: Elena will test on Linux platform...
* [svn-r5487] Purpose:Quincey Koziol2002-05-302-15/+0
| | | | | | | | | | | | | | Bug fix Description: H5Ewalk_cb was being called from a C++ API, when it really is an internal routine to the H5E interface. Solution: Removed C++ API wrapper for it. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5486] Purpose:Albert Cheng2002-05-303-83/+58
| | | | | | | | | | | Code cleanup and new feature. Description: Cleaned out some old debug print statments. Added option -B for interleaved I/O block size. (Just parsing and sanity check is done. Real I/O implementation is not done yet.) Platforms tested: eirene(pp)
* [svn-r5485] Purpose:Bill Wendling2002-05-291-25/+7
| | | | | | | | | Removal of bad code Description: Albert came up with a better way of determining which performance tests to run. I removed the broken way I did them... Platforms tested: Linux-pp
* [svn-r5484] Raymond Lu2002-05-291-14/+10
| | | | | | | | | | | | | Purpose: Bug Fixing Description: In H5FD_family_write and H5FD_family_read, size_t is checked against hsize_t for overflow, which fails on IA32 architecture machine supporting large files. Solution: Use temporary variable which won't pass the limit of size_t. Platforms tested: Linux 2.4(platinum) and IRIX64 6.5(modi4)
* [svn-r5483] Description:Albert Cheng2002-05-291-7/+29
| | | | | | | Show IO API types selected. (Changed the default setting algorithm slightly.) Platforms tested: eirene(pp)
* [svn-r5481] Description:Albert Cheng2002-05-294-12/+12
| | | | | | | Renamed pio_info_g as h5_io_info_g to better reflect its general purpose. Platforms tested: eirene(pp)
* [svn-r5477] Purpose:Albert Cheng2002-05-291-83/+66
| | | | | | updated the Dependencies file Platforms tested: no test.
* [svn-r5475] Purpose:Albert Cheng2002-05-291-2/+2
| | | | | | | Sync with changes Kent made to v1.4. still need to sync changes here back to v.14 Platforms tested: eirene(pp)
* [svn-r5472] Purpose:Albert Cheng2002-05-293-3/+3
| | | | | | | | | | | | | bug fix Description: pio_info_g has been moved to the test/libh5test.a but the pio_* source files still have the old definition and declaration. Some compilers hated the duplcation. Solution: Replaced the duplication with #include h5test.h and added test/ to the include search path too. Platforms tested: eirene, modi4.
* [svn-r5471] Purpose:Quincey Koziol2002-05-2966-1096/+1395
| | | | | | | | | | | | | | | | Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.
* [svn-r5470] Purpose:Bill Wendling2002-05-281-1/+3
| | | | | | | | | Update Description: Only print out the parameters for a run if we're in debug mode one and the 0'th process or if we're in debug mode > 0. Platforms tested: Linux
* [svn-r5469] Purpose:Bill Wendling2002-05-282-16/+163
| | | | | | | | | | | | | Feature Addition Description: Added feature which prints out the parameters and the MPI_Info object for a run for each process. Added some functions for the GPFS system. They are ifdef'ed out right now (well, they need to ahve the non-existant H5_HAVE_GPFS macro set) and aren't in use just yet. But the stub functions are there. Platforms tested: Linux
* [svn-r5468] Purpose:Quincey Koziol2002-05-282-0/+2
| | | | | | | | | | Code cleanup. Description: Included H5Eprivate.h for a couple of tests which needed it... Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5467] Purpose:Quincey Koziol2002-05-2840-543/+675
| | | | | | | | | | | | | | | | | | | | | | | | Code cleanup. Description: Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros equivalents in the SAF library and adapted them to our library. I added an additional macro which is equivalent to FUNC_ENTER: FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but none of the library or interface initialization code. This is to be used _only_ for static functions and those which explicitly cannot have the library or interface initialization code enabled (like the API termination routines, etc.). This allowed many more of the functions in the library [but not all yet :-(] to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs. It also reduced the size of the library and executables (by cutting out a bunch of code which was never executed), I'll e-mail the exact results when I've finished editing it. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5466] Purpose:Quincey Koziol2002-05-282-2/+2
| | | | | | | | | | Code cleanup. Description: Updated perl scripts to be aware of new "FUNC_ENTER_NOINIT" macro. Platforms tested: IRIX64 6.5 (modi4)

* [svn-r5463] Description:Albert Cheng2002-05-283-20/+38
| | | | | | | | | | | Folded the changes made in v1.4 into v1.5. print library version information in help page too. Specify the nofill feature supported in v1.5 only. Print the values of the KB, MB and GB in case a user wants to see them. Setup a macro, H5_HAVE_NOFILL, to indicate if Dataset no fill feature is supported. If not, --no-fill is an invalid option. Platforms tested: modi4
* [svn-r5457] MuQun Yang2002-05-231-0/+0
| | | | | | | | | | Purpose: update c++ test project to avoid linking errors Description: since gethostname etc. window-version functions may not be linked without modifying project setting in link part; we have to modify project settings for every project affected. dsets_cpp and dsets_cppdll were ignored last time. Now update it. Solution: Platforms tested: windows 2000
* [svn-r5456] Purpose:Bill Wendling2002-05-225-365/+607
