[mvapich-discuss] collectives fail under mvapich2-1.0 (fwd)

[amith rajith mamidala]

Hi Edmund,

We were able to run the 12 process test for collectives on 3 nodes.
Can you provide us some details as to how the processes were launched?
e.g. block or cyclic or any other distrubution.

thanks,

-Amith.
