[mpich-discuss] cpi

[Kenneth Raffenetti]

The error in your first message was that mpiexec was unable to find the 
file "./examples/cpi".

The error in your second message is that mpiexec was unable to find your 
"machinefile".

Please make sure you are giving the correct paths to these files in your 
mpiexec command.
