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.
