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.
