The executable MPICH builds (and you want to run) is "cpi" in the examples. cpi.c is a C source code file and is not executable. I suggest you read more on how to build and execute C programs if you still have questions.

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.

Are you executing your commands from a shared network
filesystem? If
not, have you copied your MPI installation and cpi
binaries
into the
same location on all the machines in your cluster?
