I have a Fortran 95/MPI parallel program that I run on my laptop for testing. If I have the ethernet card plugged into a live cable I can run 32 jobs on the laptop easily. If there is no cable or a dead cable plugged in then my program runs very slow. It takes for ever for the 32 processes to spawn. Rebuilding mpich (version 1.2.4) with the shared memory device does not help. Anyone know how to fix this problem?
