Also, support unlimited dimension datasets which + must use chunk storage. No parallel support for compressed datasets. + +* Collective data transfer for H5Dread/H5Dwrite. Collective access + support for datasets with contiguous storage only, thus only fixed + dimension datasets for now. + +* H5Pset_mpi and H5Pget_mpi no longer have the access_mode + argument. It is taken over by the data-transfer property list + of H5Dread/H5Dwrite. + +* New functions H5Pset_xfer and H5Pget_xfer to handle the + specification of independent or collective data transfer_mode + in the dataset transfer properties list. The properties + list can be used to specify data transfer mode in the H5Dwrite + and H5Dread function calls. + +* Added parallel support for datasets with chunked storage layout. + When a dataset is extend in a PHDF5 file, all processes that open + the file must collectively call H5Dextend with identical new dimension + sizes. + LIST OF API FUNCTIONS |
