The "type=5" suggests to me that you did not configure your mpich
library using "--with-comm=shared", but are trying to run two processes
on a node.  Mpiexec really likes to assume that you have shared memory
support if using SMP nodes.

You might look at the output of "mpiexec -v myjob" to verify that
you are using the right communication type, and are using the compute
node(s) you had planned.
