Purpose:
a bug fix for release dll
Description:
change the project setting for release dll from single-threaded to
multithreaded DLL seems to make all tests pass.
For DLL testing, it should be set to multithreaded DLL anyway.
Solution:
Platforms tested:
windows 2000
[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.]
Purpose:
Small Fix
Description:
Fixed the Min/Max/Average accumlation stuff...
Solution:
Actually thought about the code and made it accumulate the
information in the correct way.
Platforms tested:
Linux
Purpose:
Feature Fix
Description:
Added timer from open to close for write. Changed reporting of time
for write and read to only measure the actual read/write instead of
the open/close as well...
Platforms tested:
Linux(pp)
Bug fix
Description:
HDfprintf was not handling Microsoft's "%I64d" extension to printf for
printing thier '__int64' type.
Solution:
Added code to properly detect and use this extension.
Platforms tested:
None! (Kent will be testing shortly)
Purpose:
Feature Fix
Description:
Instead of outputting the # of kilobytes in a transfer size, output
the total bytes. This helps when you're interested in just doing a
copy-paste type of thing for the transfer buffer size.
Solution:
Changed the output report
Platforms tested:
Linux(pp)
Purpose:
Bug fix
Description:
In several if statements, '>' was used in place of '<='. This
caused exceptions thrown inappropriately. Replaced '>' by '<='
where applicable.
Platforms tested:
SunOS 5.7 (arabica)
Windows 98
Purpose:
Feature Add
Description:
Added output which tells how large the file is (that is, the number
of dsets * number of elements in a dset * sizeof(int)).
Platforms tested:
Linux(pp)
The default minimum xfer size of 1K was way too slow for
parallel file system like the PFS of Tflops. Set it to
128K to complete soon for default settings.
Platforms tested:
Tflops, modi4.
Bug fix
Description:
The value of H5_SIZEOF_SSIZE_T is not being updated to reflect the correct
size of the ssize_t typedef, if we have to define it ourselves.
Solution:
Undef H5_SIZEOF_SSIZE_T at beginning of block where we define the typedef
for ssize_t and then re-define it to the correct size when we've chosen a
size.
Platforms tested:
FreeBSD 4.5 (sleipnir)
Extension
Description:
int64_t type is not available everywhere.
#include H5private.h which has platform dependent hooks
to define int64_t to something available.
Platforms tested:
Tflops
Bug fix.
Description:
__int64 is not a legal type in Tflops.
Set its sizeof to 0 in the cached values.
This is a temporary fix since the real problem is
in configure which hardset __int64 to 8 for cross-compiling cases.
Platforms tested:
Tflops
Document bug
Description:
Mention that h5dump and h5ls are not displaying variable-length string
datatype information correctly. I've also entered a more detailed bug into
the bug database.
Purpose:
Small Fix
Description:
Changed how the list of drivers were listed from:
{ "driver1",
"driver2",
/* ... */
"drivern",
#ifdef FOO
"driverm"
#endif
};
to
{ "driver1"
,"driver2"
/* ... */
,"drivern"
#ifdef FOO
,"driverm"
#endif
};
since it's a nicer way of doing the same thing without the annoying
warning of an extraneous , if FOO isn't defined.
Platforms tested:
Dangermouse, Modi4, Kelgia
Purpose:
Feature Add
Description:
Added support for dumping Group Comments. This involved a
modification of the DDL as well.
Solution:
Steal code from h5ls and put it in the h5dump. The ddl.html file was
updated as normal. And a test was created...
Platforms tested:
Dangermouse, Modi4, Kelgia
Bug Fix.
Description:
Equation to compute size of attribute in memory was incorrectly using the
disk's datatype (and dataspace, but that turns out not to have been the
actual issue) and when a variable length datatype was used for the
attribute, the wrong size is being computed.
Also, the variable-length datatype conversions aren't handling the
default dataset transfer property list (H5P_DEFAULT) correctly.
Solution:
Changed attribute code to compute the attribute size in memory correctly
by using the memory datatype & dataspace.
Changed the variable-length datatype conversion code to use the default
dataset transfer property list when H5P_DEFAULT is passed as the property
list ID.
Platforms tested:
FreeBSD 4.5 (sleipnir)
Bug fix.
Description:
FreeBSD would fail the threadsafe feature if static-exec is not on.
Solution:
Force enable-static-exec on if enable-threadsafe is on.
Also moved the chunk of FreeBSD specific code for Pthread setup
from configure.in to config/freebsd.
Also changed enable-threadsafe to check on linking pthread program.
That takes care of platforms (e.g. freebsd) that has pthread
support builtin the default C library. Now one can just use
"enable-threadsafe" if the compiler has pthread support by default.
Platforms tested:
eirene, Sleipnir
Purpose:
Feature Add
Description:
Needed to add the DEV_T_IS_SCALAR macro to acconfig.h so that
autoheader will propagate that to the H5config.h file.
Solution:
Added, reran autoheader
Platforms tested:
Linux
Purpose:
Bug fix
Description:
The "make depend" command wasn't propagating down into the tools/
directories.
Solution:
Added the "depend:" part to the Makefile in the tools/ subdirectory.
Platforms tested:
Linux
Removing the DPSS (gridstorage) driver source code.
Description:
The DPSS (using Grid-Storage) driver is retired.
Removed the configure option with-gridstorage from configure.in.
Cvs remove the following files
./src/H5FDdpss.c
./src/H5FDdpss.h
./test/dpss_read.c
./test/dpss_write.c
Regenerated Dependencies files (some had to be hand-edited since
'make depend' did not cover them.)
Removed reference to DPSS Virtual file driver from H5F.c.
Platforms tested:
modi4 (Parallel; -with-gass=...), eirene, arabica (fortran, cxx).
Purpose:
Feature Fix
Description:
Added the minimum, maximum, and average time and MB/s for the write
and read operations. It now prints the report out in a pretty clear
format. It also includes how many iterations were done for the
write/read operation.
Platforms tested:
Linux
Bug fix
Description:
All processes, including those that are not part of the PIO test
sub-communicator, all attempted to run the PIO test. It resulted
in failures for those processes that are not supposed to get involved.
Solution:
The function that creates the sub-communicator also returns a
parameter indicating if the process is included in the PIO test
sub-communicator. Then only those processes will really do the
PIO test.
Platforms tested:
eirene (pp) and Modi4 (pp)
Bug Fix.
Description:
The H5Rget_object_type function could not get the object type for dataset
region references.
Solution:
Added a new function, H5Rget_obj_type, to replace H5Rget_object_type.
The new function requires the reference type as an additional parameter,
in order to allow queries on different reference types to be performed
correctly.
Platforms tested:
FreeBSD 4.4. (sleipnir)
Purpose:
Feature Fix
Description:
Changed so the "pio_perf" module handles creating and destroying the
MPI Comm. Worked it so we get the minimum, maximum, and average times
over a set of iterations.
Solution:
Lots. Had to pull the MPI Comm code from the "pio_engine" module and
place it in the "pio_perf" module. Then worked on a way to have all
processes send their time output to process 0, who collects it and
gives back the min, max, and avg times for the iterations.
Platforms tested:
Linux. Doesn't work if you use more than 1 processor...*hrmph*
Purpose:
Feature Rollback
Description:
Shared C++ libraries aren't working on all platforms (read: Arabica).
We need to switch to the old method until we can sort this out.
Solution:
Re-add the "-static" flag to the library creation lines.
Purpose:
Bug Fix
Description:
There were weird "throw()"s which were being placed into the
configure script. Some C++ compilers were barfing on this syntax
(which was akin to "extern int exit(int) throw ();" wonder why?).
Solution:
Ran a different autoconf on the configure file which I'd downloaded
from ftp.gnu.org. It doesn't have those "throw()"s anymore
Platforms tested:
Linux
Purpose:
Bug Fix
Description:
The --raw, --hdf5, --mpiio options weren't being done correctly.
Solution:
I had to change some of the tests for the io_type to & instead of |
so that they'd work how I wanted them to work.
Platforms tested:
Linux
Bug Fix
Description:
Added regression test for proper library behavior when adding fields past
the end of a datatype.
Platforms Tested:
FreeBSD 4.4 (sleipnir)
Bug Fix
Description:
H5Tinsert was allowing compound datatype fields to be inserted past the end
of the datatype.
Solution:
Added range check in H5T_insert
Platforms Tested:
FreeBSD 4.4 (sleipnir)
Purpose:
Bug Fix
Description:
Shared libraries weren't being built for C++.
Solution:
Removed the -static flag from the libtool compile line. This allows
both shared and static libraries to be built instead of just static
ones. After talking with Quincey and Binh-Minh, there shouldn't be
any reason for C++ to be built static only.
Platforms tested:
Linux
Purpose:
Feature Changes
Description:
Okay, I needed to add in more parameters so that the user can modify
how things are supposed to work with the PIO programs. Also needed
to change the algorithm a bit to make these work. And needed to add
in timing for the READ option.
Solution:
Added the above things. The parameters took a major rewrite of the
command-line parsing stuff. Here's the usage statement:
usage: pio_perf [OPTIONS]
OPTIONS
-h, --help Print a usage message and exit
-d N, --num-dsets=N Number of datasets per file [default:1]
-f S, --file-size=S Size of a single file [default: 64M]
-F N, --num-files=N Number of files [default: 1]
-H, --hdf5 Run HDF5 performance test
-i, --num-iterations Number of iterations to perform [default: 1]
-m, --mpiio Run MPI/IO performance test
-o F, --output=F Output raw data into file F [default: none]
-P N, --max-num-processes=N Maximum number of processes to use [default: 1]
-p N, --min-num-processes=N Minimum number of processes to use [default: 1]
-r, --raw Run raw (UNIX) performance test
-X S, --max-xfer-size=S Maximum transfer buffer size [default: 1M]
-x S, --min-xfer-size=S Minimum transfer buffer size [default: 1K]
F - is a filename.
N - is an integer >=0.
S - is a size specifier, an integer >=0 followed by a size indicator:
K - Kilobyte
M - Megabyte
G - Gigabyte
Example: 37M = 37 Megabytes
Platforms tested:
Linux, but not fully finished...
Purpose:
Bug Fix
Description:
Committing the changes in the MPI/IO stuff so that parallel HDF5
will work on HP-UX. It seems that on HP-UX, the MPI_Status variable
needs to be initialized to 0 for it to work (i.e., in some other MPI
calls, if there's garbage in the MPI_Status variable, then it will
barf).
Solution:
Initialized to 0.
Platforms tested:
HP-UX parallel, Linux.
Added nfiles and ndsets parameters checking.
Removed iteration variable since iterations would be done
in Control routine.
Platforms tested:
Eirene(pp) and modi4(pp)
