|
|
|
HDF5 Release 1.8.0 is a major release with many changes and new features.
|
|
|
|
New format and interface features discussed in the "What's New in
|
|
HDF5 1.8.0" document include the following:
|
|
|
|
Enhanced group object management
|

|
|
External and user-defined links
|
|
New high-level APIs:
|
|
HDF5 Packet Table (H5PT) and HDF5 Dimension Scale (H5DS)
|
|
C++ and Fortran interfaces for older high-level APIs:
|
|
H5Lite (H5LT), H5Image (H5IM), and H5Table (H5TB)
|
|
New and improved tools
|
|
And more...

|
|
|
New APIs associated with these features, other interface changes
|
|
(e.g., ENUM and struct definitions), and new library configuration flags
|
|
are listed in the "Release 1.8.0 (current release) versus Release 1.6.x"
|
|
section of "HDF5 Software Changes from Release to Release."

|
|
Compatibility
|
|
-------------
|
|
Many HDF5 users and user communities have existing applications that
|
|
they may wish to port to Release 1.8.0. Alternatively, some users may
|
|
wish to take advantage of Release 1.8.0's improved performance without
|
|
having to port such applications. To facilitate managing application
|
|
compatibility and porting applications from release to release, the HDF
|
|
Team has implemented the following features:
|
|
Individually-configurable macros that selectively map common
|
|
interface names to the old and new interfaces
|
|
Library configuration options to configure the macro mappings
|
|
|
|
Two related documents accompany this release:
|
|
"API Compatibility Macros in HDF5" discusses the specifics of the
|
|
new individually-configurable macros and library configuration
|
|
options.

|
|
|
|
"New Features in HDF5 Release 1.8.0 and Backward/Forward Format
|
|
Compatibility Issues" discusses each new feature with regard to
|
|
its impact on format compatibility.

|
|
|
|
Removed Feature
|
|
===============
|
|
The stream virtual file driver (H5FD_STREAM) have been removed in this
|
|
release. This affects the functions H5Pset_fapl_stream and H5Pget_fapl_stream
|
|
and the constant H5FD_STREAM.
|
|
|
|
This virtual file driver will be available at
|
|
http://hdf5-addons.origo.ethz.ch/. Note that at the time of this release,
|
|
the transition is still in progress; the necessary integration tools may
|
|
not be available when HDF5 Release 1.8.0 first comes out.
|
|
|
|
|
|
Support for New Platforms, Languages, and Compilers
|
|
===================================================
|
|
- Support for Open VMS 7.3 was added.
|
|
|
|
|
|

|
Known Problems
|
|
==============
|
|
* We have discovered two problems when running collective IO parallel HDF5
|
|
tests with chunking storage on the ChaMPIon MPI compiler on tungsten, a
|
|
Linux cluster at NCSA.
|
|
|
|
Under some complex selection cases:
|
|
1) MPI_Get_element returns the wrong value.
|
|
2) MPI_Type_struct also generates the wrong derived datatype and corrupt
|
|
data may be generated.
|
|
These issues arise only when turning on collective IO with chunking storage
|
|
with some complex selections. We have not found these problems on other
|
|
MPI-IO compilers. If you encounter these problems, you may use independent
|
|
IO instead.
|
|
|
|
To avoid this behavior, change the following line in your code
|
|
H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_COLLECTIVE);
|
|
|
|
to
|
|
H5Pset_dxpl_mpio(xfer_plist, H5FD_MPIO_INDEPENDENT);
|
|
|
|
KY - 2007/08/24
|
|
|
|
* For SNL, spirit/liberty/thunderbird: The serial tests pass but parallel
|
|
tests failed with MPI-IO file locking message. AKC - 2007/6/25
|
|
|
|
* On Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers,
|
|
use -mp -O1 compilation flags to build the libraries. A higher level of
|
|
optimization causes failures in several HDF5 library tests.
|
|
|
|
* For SNL, Red Storm: Only parallel HDF5 is supported. The serial tests pass
|
|
when run against the parallel library; the parallel tests also pass, but
|
|
with lots of non-fatal error messages.
|
|
|
|
* For LLNL, uP: both serial and parallel tests pass.
|
|
Zeus: Serial tests pass but parallel tests fail with a known problem in MPI.
|
|
ubgl: Serial tests pass but parallel tests fail.
|
|
|
|
* On SUN 5.10 C++, testing fails in the "Testing Shared Datatypes with
|
|
Attributes" test.
|
|
|
|
* Configuring with --enable-debug=all produces compiler errors on most
|
|
platforms: Users who want to run HDF5 in debug mode should use
|
|
--enable-debug rather than --enable-debug=all to enable debugging
|
|
information on most modules.
|
|
|
|
* On Mac OS 10.4, test/dt_arith.c has some errors in conversion from long
|
|
double to (unsigned) long long and from (unsigned) long long to long double.
|
|
|
|
* On Altix SGI with Intel 9.0, testmeta.c would not compile with -O3
|
|
optimization flag.
|
|
|
|
* On VAX, the Scaleoffset filter is not supported. The filter cannot be
|
|
applied to HDF5 data generated on VAX. The Scaleoffset filter only supports
|
|
the IEEE standard for floating-point data.
|
|
|
|
* On Cray X1, a lone colon on the command line of h5dump --xml (as in
|
|
the testh5dumpxml.sh script) is misinterpereted by the operating system
|
|
and causes an error.
|
|
|
|
* On mpich 1.2.5 and 1.2.6, if more than two processes contribute no IO and
|
|
the application asks to do collective IO, we have found that when using 4
|
|
processors, a simple collective write will sometimes be hung. This can be
|
|
verified with t_mpi test under testpar.
|
|
|
|
* On IRIX6.5, when the C compiler version is greater than 7.4, complicated
|
|
MPI derived datatype code will work. However, the user should increase
|
|
the value of the MPI_TYPE_MAX environment variable to some appropriate value
|
|
to use collective irregular selection code. For example, the current
|
|
parallel HDF5 test needs to raise MPI_TYPE_MAX to 200,000 to pass the test.
|
|
|
|
* A dataset created or rewritten with a v1.6.3 library or after cannot be read
|
|
with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled.
|
|
There was a bug in the calculating code of the Fletcher32 checksum in the
|
|
library before v1.6.3; the checksum value was not consistent between big-
|
|
endian and little-endian systems. This bug was fixed in Release 1.6.3.
|
|
However, after fixing the bug, the checksum value was no longer the same as
|
|
before on little-endian system. Library releases after 1.6.4 can still read
|
|
datasets created or rewritten with an HDF5 library of v1.6.2 or before.
|
|
SLU - 2005/6/30
|
|
|
|
* For version 6 (6.02 and 6.04) of the Portland Group compiler on the AMD
|
|
Opteron processor, there is a bug in the compiler for optimization(-O2).
|
|
The library failed in several tests, all related to the MULTI driver.
|
|
The problem has been reported to the vendor.
|
|
|
|
* 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",
|
|
but HDF5 does not use sockets. This failure is due to problems with the
|
|
poe command trying to set up the debug socket. To resolve this problem,
|
|
check to see whether there are many old /tmp/s.pedb.* files staying around.
|
|
These are sockets used by the poe command and left behind due to failed
|
|
commands. First, ask your system administrator to clean them out.
|
|
Lastly, request IBM to provide a means to run poe without the debug socket.
|
|
|
|
* 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 do not use this option on these platforms
|
|
during configuration.
|
|
|
|
* With the gcc 2.95.2 compiler, HDF5 uses the `-ansi' flag during
|
|
compilation. The ANSI version of the compiler complains about not being
|
|
able to handle the `long long' datatype with the warning:
|
|

warning: ANSI C does not support `long long'
|
|
|
|
This warning is innocuous and can be safely ignored.

|
* The ./dsets tests fail on 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.
|
|
|
|
* Not all platforms behave correctly with Szip's shared libraries. Szip is
|
|
disabled in these cases, and a message is relayed at configure time. Static
|
|
libraries should be working on all systems that support Szip and should be
|
|
used when shared libraries are unavailable.
|
|
|
|
There is also a configure error on Altix machines that incorrectly reports
|
|
when a version of Szip without an encoder is being used.
|
|
|
|
* On some platforms that use Intel and Absoft compilers to build the HDF5
|
|
Fortran library, compilation may fail for fortranlib_test.f90, fflush1.f90
|
|
and fflush2.f90 complaining about the exit subroutine. Comment out the line
|
|
IF (total_error .ne. 0) CALL exit (total_error).
|
|
|
|
* Information about building with PGI and Intel compilers is available in
|
|
the INSTALL file sections 4.7 and 4.8.
|
|
|
|
* 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 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 HDF5 make files and test scipts 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.
|
|
|
|
* H5Ocopy() does not copy reg_ref attributes correctly when shared-message
|
|
is turn on. The value of the reference in the destination attriubte is
|
|
wrong. This H5Ocopy problem will affect the h5copy tool.
