I am running ParaView with MPICH v1.2.5 on a 2-node cluster (each node =
is a dual processor Xeon 2.2GHz running RedHat 8.0-smp--total of 4 =
processors in cluster). When I run ParaView with "mpirun -np 4 =
ParaView", my system monitor shows a maximum of 50% cpu usage on each =
node, giving 25% to each ParaView process. If I run Paraview with =
"mpirun -np 8 ParaView", I still get 25% for each process, but 4 =
processes on each node, and a maximum of 100% total cpu usage. Why won't =
ParaView use more than 25% of a cpu in one process, and why can I only =
get 50% usage with mpirun -np 4?
