[mvapich-discuss] mvapich2 2.3a on ppc64le

[Hari Subramoni]

Hello,

Sorry to hear that you are facing issues. These are two separate issues
actually. Could you please let us know what program you are running? That
will help us narrow the issue down further.

Thx,
Hari.

Hi

    I am trying to use mvapich2 2.3a on a 2 node ppc64le system with 8
threads per core (total threads per node of 160)

    There appears to be a bug in ptmalloc that prevents correct startup
related to setting the affinity.

without InfiniBand registration cache support.
