[mpich-discuss] Error while using MPI_Send

[Kenneth Raffenetti]

Hi,

Normally this type of error would be the result of a firewall blocking 
communication, but your run is on a single node so that shouldn't be the 
case. I wonder, since it did work at one point, if there is some bad 
state on your system that might be cleared with a reboot?

It also looks like you are running on a Android system, which we do not 
have much experience with, and no good way to test ourselves so our ways 
to help may be limited.
