[mvapich-discuss] Error in final mpicc, mpiCC,

Mon Sep 24 22:56:21 EDT 2007

David - We tried mpi_sendrecv on message sizes > 4 MB on various
system configurations and platforms with mvapich2-1.0. Things seem to
be working fine. We are not able to reproduce the error you are
mentioning. Could you let us know details of the situation where you
are seeing the mpi_sendrecv failure.

Thanks, 

DK
