RE: [openib-general] OFED-1.0-rc6 is available

[Scott Weitzenkamp (sweitzen)]

The MTU change undos the changes for bug 81, so I have reopened bug 81 (http://openib.org/bugzilla/show_bug.cgi?id=81).   With rc6, PCI-X osu_bw and osu_bibw performance is bad, and PCI-E osu_bibw performance is bad.  I've enclosed some performance data, look at rc4 vs rc5 vs rc6 for Cougar/Cheetah/LionMini.   Are there other benchmarks driving the changes in rc6 (and rc4)?   Scott Weitzenkamp SQA and Release Manager Server Virtualization Business Unit Cisco Systems     OSU MPI: ·        Added mpi_alltoall fine tuning parameters ·        Added default configuration/documentation file $MPIHOME/etc/mvapich.conf ·        Added shell configuration files  $MPIHOME/etc/mvapich.csh , $MPIHOME/etc/mvapich.csh ·        Default MTU was changed back to 2K for InfiniHost III Ex and InfiniHost III Lx HCAs. For InfiniHost card recommended value is: VIADEV_DEFAULT_MTU=MTU1024
