No, the size of the compressed chunks will generally be different for different chunks (unless they contain the exact same data). In the worst case, the size of a compressed chunk could be larger than the original chunk size. > Secondly, I need to understand the issue about space allocation on > compression in parallel: Compression is currently (!) not supported for parallel writes. However, you can read compressed datasets in parallel. Best, G. _______________________________________________ Hdf-forum is for HDF software users discussion.
