The listing indicates that 224 processors are application nodes (APP),
two are operating system nodes (OS), and 12 are command nodes (CMD).
This listing also shows that two processors were non-operational. Four
parallel jobs were running using 16–64 processors.
The listing also shows that all processors have the clock rate of 375 MHz.
Earlier there were processors having different clock rates, but now all
are running at the same speed.
The grmview command also shows the coordinates of the PEs in the 3D
torus. You can see that the size of the torus is 8 × 4 × 7, so the torus is
not a complete cube.
The top command gives a global picture of the system status at a glance.
Here is an example of the output:

This listing shows that currently about 67% of the computer is used for
computing. The top command also shows the total memory usage and
the total memory requirements of the running processes.
