Default Case

Invoke the following command:

mpirun -np P IMB-<..>

All benchmarks run on Q=[1,] 2, 4, 8, ..., largest 2x<P, P processes (Q=1 as discussed above IMB-IO).

For example: P=11, then Q=[1,]2,4,8,11 processes will be selected. The Single Transfer IMB-IO benchmarks run with Q=1, the Single Transfer IMB-EXT benchmarks  with Q=2.

The Q processes are the active processes.
