Release information for hdf-5.0.0a ---------------------------------- 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 SP2 and 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/" +) Future plan for parallel HDF5 1) support for Intel Teraflop platform. 2) support for unlimited dimension datasets. 3) support for collective access to datasets. 4) support for independent create/open of datasets.
