Release information for hdf5-1.0.0a
|
|
----------------------------------
|
|
|
|
This release is an beta release for functionality necessary for the
|
|
ASCI vector bundle project in a serial environment. Some parallel
|
|
support is also available. Other features should be considered alpha
|
|
quality.
|
|
|
|
The following functions are implemented. Errors are returned if an
|
|
attempt is made to use some feature which is not implemented and
|
|
printing the error stack will show `not implemented yet'.

Release information for parallel HDF5
|
|
-------------------------------------
|
|
|
|
+) Current release supports independent access to fixed dimension datasets
|
|
only.
|
|
|
|
+) The comm and info arguments of H5Cset_mpi are not used. All parallel
|
|
I/O are done via MPI_COMM_WORLD. Access_mode for H5Cset_mpi can be
|
|
H5ACC_INDEPENDENT only.
|
|
|
|
+) This release of parallel HDF5 has been tested on IBM SP2 and SGI
|
|
Origin 2000 systems. It uses the ROMIO version of MPIO interface
|
|
for parallel I/O supports.
|
|
|
|
+) Useful URL's.
|
|
Parallel HDF webpage: "http://hdf.ncsa.uiuc.edu/Parallel_HDF/"
|
|
ROMIO webpage: "http://www.mcs.anl.gov/home/thakur/romio/"
|
|
|
|
+) Some to-do items for future releases
|
|
support for Intel Teraflop platform.
|
|
support for unlimited dimension datasets.
|
|
support for file access via a communicator besides MPI_COMM_WORLD.
|
|
support for collective access to datasets.
|
|
support for independent create/open of datasets.
