Hi, I'm using the environmental variable MPICH_MPIIO_HINTS, to dump the mpiio configuration, but apparently, many layers(HDF5, Filesystems, etc) can overwrite the hints that passed in by the user. I think MPICH_MPIIO_HINTS can only grab the static information, not the runtime info. I'm wondering if there is anyway to accurately print out the MPIIO information without hacking the source codes? Thanks,
First off, I don't have any idea what Cray is doing with their MPI implementation. They don't share their code with us, so you'd better contact them for support. I'm going to guess that MPICH_MPIIO_HINTS is really doing what you want -- if it's not, that's a bug and you should contact cray about that. ==rob _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
