[mvapich-discuss] Application aborts at runtime.

[Hari Subramoni]

Hi Chaitra,

It seems like you are using the socket channel here. In this case, you can
directly use the TCP/IP nemesis channel.

Please refer to the following section of the userguide for more information.

http://mvapich.cse.ohio-state.edu/static/media/mvapich/mvapich2-2.1-userguide.html#x1-170004.9

Alternately, you can also try to use MPICH directly.

On a side note, can you please try to use MVAPICH2-2.1 and see if the error
persists?

Regards,
Hari.
