Hello:
I am trying to execute an MPI program on a 4-node AMD Opteron Beowulf cluster running Fedora Core 3. We have installed LAM/MPI 7.1.1. The MPI
program (arps) is written in Fortran and needs to read a Namelist file that is redirected to standard input. For some reason, the straightforward approach:
mpirun -np 16 n0,1,2,3 arps < arps.input > arps.output
is not effective: the program sits and waits for standard input. I do not have this problem when I run non-MPI programs, nor does this happen when
I use MPICH. I have tried using the -w and -nw flags, but neither solves the problem.
Any ideas?
