node1:~/meep-0.9/tests# mpirun -np 20 ./bench
Using MPI version 1.2, 20 processes
...
However, there are only two CPUs in my PC.
What happened?
Many thanks!

I suppose you like to call mpirun
mpirun -np 4 ./bench
will invoke bench with 4 nodes.
argv is the parameter string given during program calls
e.g. the control file name for mpb or meep
