hi all, new to this list, so don't know if this is offtopic. i'd like to know experiences about MPI performance gain with jumbo frames. i manage a beowulf cluster (42 athlon xp, gentoo linux) with gigabit ethernet where fluent, openfoam and other mpi apps are run. with NFS i'm sure wich kind of gain i would have, but with MPI apps i'm worried about after seeing this page http://www.scl.ameslab.gov/Projects/IBMCluster/Benchmarks.html regards
