adjustment. The size can be increased and decreased(without
cutting the last member). No API change is involved. SLU -
2004/10/1
- Removed PABLO support
2005/01/20 EIP
Parallel Library:
-----------------
- Allow compressed, chunked datasets to be read in parallel.

=======================================
Bug Fixes since HDF5-1.6.3 release
==================================
Library
-------
- Fix segmentation fault when calling H5Fflush with an attribute that
hasn't had a value written to it open. QAK - 2004/10/18
- Back up supporting bitfield and time types in H5Tget_native_type.
Leave it to future support. The function simply returns error
message of "not support" for bitfield and time types.
SLU - 2004/10/5
- Fixed address check in Core VFL driver to avoid spurious address/size
overflows for odd valued addresses and/or sizes. QAK - 2004/09/27
- Fixed problem where chunked datasets were not able to be deleted
from a file under certain circumstances. QAK - 2004/09/27/
Configuration
-------------
- IRIX64 MIPSpro compiler of 7.4.x supports C99 features. Default
to use the 'c99' compiler if available. AKC - 2004/12/13
- Intel v8.0 compiler would infinite loop when compiling some test
code with -O3 option. Changed enable-production default compiler
option to -O2. AKC - 2004/12/06
- Long double is assumed to be a supported C data type. It is a
stanadard C89 type. AKC - 2004/10/22
Performance
-------------
Tools
-----
- Fixed h5dump to print attributes data in ASCII if -r option is used.
AKC - 2004/11/18
- Fixed space utilization reported in h5ls to correct error in formula
used. QAK - 2004/10/22

Known Problems
==============
* Newer SGI MIPSpro compilers (version 7.4.x) support C99 features but it
has a "guard" statement in stdint.h that will #error and skip the rest
of the header file if C99 option is not used explicitely. Hardset
$CC to c99 will resolve the problem. AKC - 2004/12/13
* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
messages like "INFO: 0031-XXX ...". This is from the command poe.
Set the environment variable MP_INFOLEVEL to 0 to minimize the messages
and run the tests again.
The tests may fail with messages like "The socket name is already
in use". HDF5 does not use sockets (except for stream-VFD). This is
due to problems of the poe command trying to set up the debug socket.
Check if there are many old /tmp/s.pedb.* staying around. These are
sockets used by the poe command and left behind due to failed commands.
Ask your system administrator to clean them out. Lastly, request IBM
to provide a mean to run poe without the debug socket.
* h5fc and h5c++ compilation scripts have a bug: object files (*.o) cannot be
created when source code is compiled using h5fc or h5c++. We will provide
a fix. Please check ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/src/patches/
for the patches.
* Fortran subroutine h5pget_driver_f doesn't return a correct driver information.
* There are two h5dump xml tests(h5dump --xml thlink.h5 and h5dump --xml tmany.h5)
failed on windows xp with .NET for debug and debug dll. Release and Release
dll work fine.
* The h5dump tests may fail to match the expected output on some platforms
(e.g. parallel jobs, Windows) where the error messages directed to
"stderr" do not appear in the "right order" with output from stdout.
This is not an error.
* The stream-vfd test uses ip port 10007 for testing. If another
application is already using that port address, the test will hang
indefinitely and has to be terminated by the kill command. To try the
test again, change the port address in test/stream_test.c to one not
being used in the host.
* The --enable-static-exec configure flag fails to compile for Solaris
platforms. This is due to the fact that not all of the system
libraries on Solaris are available in a static format.
The --enable-static-exec configure flag also fails to correctly compile
on IBM SP2 platform for the serial mode. The parallel mode works fine
with this option.
It is suggested that you don't use this option on these platforms
during configuration.
* The Stream VFD was not tested yet under Windows. It is not supported
in the TFLOPS machine.
* The ./dsets tests failed in the TFLOPS machine if the test program,
dsets.c, is compiled with the -O option. The hdf5 library still works
correctly with the -O option. The test program works fine if it is
compiled with -O1 or -O0. Only -O (same as -O2) causes the test
program to fail.
* Certain platforms give false negatives when testing h5ls:
- Cray J90 and Cray T90IEEE give errors during testing when displaying
some floating-point values. These are benign differences due to
the different precision in the values displayed and h5ls appears to
be dumping floating-point numbers correctly.
* Before building HDF5 F90 Library from source on Crays
replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src
subdirectory in the top level directory with the Cray-specific files
from the site:
ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/src/patches/
* On some platforms that use Intel and Absoft compilers to build HDF5 fortran library,
compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90
complaining about exit subroutine. Comment out the line
IF (total_error .ne. 0) CALL exit (total_error)
* On IA32 and IA64 systems, if you use a compiler other than GCC (such as
Intel's ecc or icc compilers), you will need to modify the generated
"libtool" program after configuration is finished. On or around line 104 of
the libtool file, there are lines which look like:
# How to pass a linker flag through the compiler.
wl=""
change these lines to this:
# How to pass a linker flag through the compiler.
wl="-Wl,"
UPDATE: This is now done automatically by the configure script. However, if
you still experience a problem, you may want to check this line in the
libtool file and make sure that it has the correct value.
* Information about building with PGI and Intel compilers is available in
INSTALL file sections 5.7 and 5.8
* In LANL QSC, the new cc compiler has problems converting small values of
long long (absolute values less than 1**-308) to double. This triggers
the test/dtypes to report failure in the
Testing random sw long double -> double conversions
If -ieee is used, the converted doubles spread over the range 0.0 to 1**-308.
If -ieee is not used, the converted double values are mostly 0.0 but
occasionally as 1**-308. This has been reported to the system staff.
All other tests have passed.
* The C++ library's tests fails when compiling with PGI C++ compiler. The
workaround until the problem is correctly handled is to use the
flag "--instantiate=local" prior to the configure and build steps, as:
setenv CXX "pgCC --instantiate=local" for pgCC 5.02 and higher
setenv CXX "pgCC -tlocal" for others
* On at least one system, (SDSC DataStar), the scheduler (in this case
LoadLeveler) sends job status updates to standard error when you run
any executable that was compiled with the parallel compilers.
This causes problems when running "make check" on parallel builds, as
many of the tool tests function by saving the output from test runs,
and comparing it to an exemplar.
The best solution is to reconfigure the target system so it no longer
inserts the extra text. However, this may not be practical.
In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to
the configure and build. This will cause "make check" to continue after
detecting errors in the tool tests. However, in the case of SDSC DataStar,
it also leaves you with some 150 "failed" tests to examine by hand.
A second solution is to write a script to run serial tests and filter
out the text added by the scheduler. A sample script used on SDSC
DataStar is given below, but you will probably have to customize it
for your installation.
Observe that the basic idea is to insert the script as the first item
on the command line which executes the test. The script then
executes the test and filters out the offending text before passing
it on.
#!/bin/csh
set STDOUT_FILE=~/bin/serial_filter.stdout
set STDERR_FILE=~/bin/serial_filter.stderr
rm -f $STDOUT_FILE $STDERR_FILE
($* > $STDOUT_FILE) >& $STDERR_FILE
set RETURN_VALUE=$status
cat $STDOUT_FILE
tail +3 $STDERR_FILE
exit $RETURN_VALUE
You get the HDF make files and test scripts to execute your filter script
by setting the environment variable "RUNSERIAL" to the full path of the
script prior to running configure for parallel builds. Remember to
"unsetenv RUNSERIAL" before running configure for a serial build.
Note that the RUNSERIAL environment variable exists so that we can
can prefix serial runs as necessary on the target system. On DataStar,
no prefix is necessary. However on an MPICH system, the prefix might
have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to
get the serial tests to run at all.
In such cases, you will have to include the regular prefix in your
filter script.
