Hey, I'm working on a Beowulf Cluster for a class project, and we are using PelicanHPC for the OS ... anyhow the problem is, is we are trying to find a way to show the technologically impaired people that will be judging this project and currently we are trying to use srry i'm in a hurry

mpirun -np # octave -q --eval "kernal_example (2000, true)"

They say to set # at +1 of the number of cores you have ... however when i'm running/unplugging computers the number stays the same which doesn't make since ie: (these where all done with the same # of computers ( 3 computers 4 cores))

ser@pel1:~$ mpirun -np 3 octave -q --eval "kernel_example(2000,true)"
