The serial HDF5 might not work at all on a large supercomputer, because the way MPB does parallel I/O using the serial HDF5 library is somewhat hackish. However, I'm not sure if the parallel version of HDF5 works correctly with the current version of MPB either, unfortunately; I've had reports of it hanging too, but I haven't tried it for a while. _______________________________________________ mpb-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/mpb-discuss
