MPICH (p4mpd) trouble

The usual reason for this is that the executable cannot be found on the
remote machine. First make sure that it is there (either by copying it
there or by having a shared file system), and then make sure that it can
be found (either by supplying the full path name on the mpirun command
or by putting the path to the executable in your environment).
MPICH problems should in general be sent to mpi-bugs at mcs.anl.gov instead
of to the beowulf list.
| New to MPI, I'm setting up mpich 1.2.4 on my x86 linux box (Redhat 8.0
| ). Using the mpd daemon sounds like the cleanest way to accomplish
| this, so I did the following as perscribed in the manual:
| ./configure --with-device=ch_p4mpd --prefix=/usr/local/mpich-1.2.4
| make install
| I created a .mpd.conf under /root and used chmod -o to make it
| inaccessible to other users (as required by mpd ).
| I can manually start mpd without a problem, but I can't run the
| examples. For example, if I do "mpirun -np 3 cpi" I immediately get
| the error "job 1 aborted with code0 by process 2, unable to execute
| program: cpi"
