If so, which hints does it support?If you are using the Lustre ADIO driver (patch for MPICH-1.2.6 in the lustre/contrib/ directory) then it supports the "striping_unit" and "striping_factor" hints. I''m not sure if this was ever included into upstream MPICH releases. Cheers, Andreas -- Andreas Dilger Principal Software Engineer Cluster File Systems, Inc.
