It is therefore not + * possible to set a collective requirement individually for those operations. The + * only solution with the HDF5 1.10.0 release is to set the collective requirement + * globally on H5Fopen() or H5Fcreate() for all metadata operations to be + * collective. + * + * The following is a list of those functions in the HDF5 library. This list is + * integral to the discussion in the H5Pset_all_coll_metadata_ops() entry: + * + * <pre> + * + * H5Awrite() + * H5Aread() + * H5Arename() + * H5Aiterate2() + * H5Adelete() + * H5Aexists() + * + * H5Dget_space_status() + * H5Dget_storage_size() + * H5Dset_extent() + * H5Ddebug() + * H5Dclose() + * H5Dget_create_plist() + * H5Dget_space() (when dataset is a virtual dataset) + * + * H5Gget_create_plist() + * H5Gget_info() + * H5Gclose() + * + * H5Literate() + * H5Lvisit() + * + * H5Rcreate() + * H5Rdereference2() (when reference is an object reference) + * H5Rget_region() + * H5Rget_obj_type2() + * H5Rget_name() + * + * H5Ocopy() + * H5Oopen_by_addr() + * H5Oincr_refcount() + * H5Odecr_refcount() + * H5Oget_info() + * H5Oset_comment() + * H5Ovisit() + * + * H5Fis_hdf5() + * H5Fflush() + * H5Fclose() + * H5Fget_file_image() + * H5Freopen() + * H5Fget_freespace() + * H5Fget_info2() + * H5Fget_free_sections() + * H5Fmount() + * H5Funmount() + * + * H5Iget_name() + * + * H5Tget_create_plist() + * H5Tclose() + * + * H5Zunregister() + * </pre> + * + * In addition, \b most deprecated functions fall into this category. + * + * The HDF Group may address the above limitation in a future major release, but + * no decision has been made at this time. Such a change might, for example, + * include adding new versions of some or all the above functions with an extra + * property list parameter to allow an individual setting for the collective + * calling requirement. + * + * \sa_metadata_ops + */ |
