[Mvapich-discuss] ch3:nemesis mvapich2-2.3.7-1 compile error

[Panda, Dhabaleswar]

Hi Chuck,

Are you able to install Cornelis OPX library over OFI on your system? If so, you should be able to use the latest MVAPICH 3.0 and MVPICH-Plus 3.0 on your system without any problem.

Thanks,

DK

Hi Hari-

    We've got an older ~600 node Cray connected by an Intel/Qlogic TrueScale
12800-360 Infiniband switch which uses psm via ch3:psm.  The MVAPICH
download page indicates we should use legacy 2.3.7 instead of 3.0.
is that correct?

    we sometimes use ch3:nemesis in addition to ch3:psm in order to
route MPI over ipoib when we have apps that want to use PSM directly
via the libpsm_infinipath.so library.

    be happy to switch to MVAPICH 3.0 if it now works with psm
libpsm_infinipath.so.

chuck
