I am working on a Beowulf Computer Cluster and when I try and run
programs that
implement MPI, it states that the size is set to 1. (The size of my cluster is
4.) I lamboot all the nodes through a lam-bhost.def file and they boot
successfully. I determined this by running MPI_Comm_size through Octave:
octave:> [info size] = MPI_Comm_size(MPI_COMM_WORLD)
info=0
size=1
Also, when I run the programs that implement MPI, they state that the
number of
processors is 1. Is there any way to manually set MPI_Comm_size, or is there
something that I am doing wrong while lambooting the cluster?
I am not "mpirun-ing" the programs either, I'm simply entering the
directory and
"./-ing" them. Should I be doing something different?
Forgive me, I'm new! Thanks for the help!
