[mvapich-discuss] mvapich2 1.4.0 and MPI_Comm_Spawn fatal errors

[Dhabaleswar Panda]

Dr. Kallies - Thanks for reporting this error in the mpich2 sources
distributed with mvapich2. We will examine this and make this change in
the MVAPICH2 branch version. For our next mvapich2 release, we are working
on updating to the latest MPICH2 1.2.1 release.

Thanks,

DK
