Thank you for the clarification. Following on from Jerome's suggestion of installing my own compression algorithm (or library) within the routines where I call HDF5, is it possible to use H5Zregister and H5Pset_filter to define another compression type (e.g. bzip2)? Or would this still not work in parallel? If not,
H5Zregister and its friends must be used. I have just had a look to pxz (C) code which parallelizes xz via OMP: it sounds very easy: I am quite sure that you can adapt the code to H5Zregister an OMP parallelized xz compressor. Before using your xz filter, you may consider (and try) other filters. You may compress within HDF5 not outside (namely, avoid to compress the h5 data file itself: it may be less efficient). My 2 cents, Jerome _______________________________________________ Hdf-forum is for HDF software users discussion. [email protected] http://mail.hdfgroup.org/mailman/listinfo/hdf-forum_hdfgroup.org
