I can reproduce this.  I don't know if the change was intentional, so
I'm cross-posting.  MPICH developers: a shell script containing multiple
mpiexec commands no longer makes it past the first one.  Apparently one
now needs to set stdin to /dev/null to continue.


$ cat t.sh
#!/bin/sh

$MPIEXEC -n 1 hostname
$MPIEXEC -n 1 date

## MPICH-3.1b1 (also 3.0 series), "date" output not printed
$ MPIEXEC=/opt/mpich/bin/mpiexec ./t.sh &

$ batura


[5]+  Stopped                 MPIEXEC=/opt/mpich/bin/mpiexec ./t.sh


## Open MPI - note that "date" output is printed
$ MPIEXEC=/usr/bin/mpiexec ./t.sh &
