[mvapich-discuss] Hardware problem or code bug?

[Lana Deere]

The following error is occurring rarely when running an MPI program.  I am
not able to interpret what the error is saying, so any help decoding this
would be appreciated.  In particular, does anyone know whether this is a
sign of an infiniband hardware error or rather an intermittent software bug?
