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, Best, Jialin _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
