[mpich-discuss] Support for BLCR

[kishor kharbas]

Thank you Pavan and Darius for your help.

I am in the process of running MPI application with check-pointing, but I am
facing a problem in running the application(without checkpoint) at the first
place. I tried running the application on 2 processing nodes with default
HYDRA process manager.

Command : $: ../bin/mpiexec -np 2 ./mpiexample
(host file has domain names for 2 hosts)

The error shown is -
    *Fatal error in MPI_Send: Other MPI error, error stack:
   MPI_Send(174).................**....: MPI_Send(buf=0x7fff379fabb8,
count=1, MPI_INT, dest=1, tag=0, MPI_COMM_WORLD) failed
   MPIDI_CH3I_Progress(165)......**....:
   MPID_nem_mpich2_blocking_recv(**895):
   MPID_nem_tcp_connpoll(1714)...**....: Communication error*

Can you please suggest how can I find the cause for this error.

Thanks,
Kishor
