Hello everybody,

Michel, you may think of the CPU space as divided in two, according to the
state: for example, if you express CPU in units of Bytes, some of the Bytes will be in the state "free" and others will be in the state "occupied".

So you'd have two stocks (one for each state), and two flows: if someone loads an application into the CPU, the corresponding number of Bytes flows from "free" to "occupied", and once the application is terminated, the Bytes flow back to "free". (Of course I do not know if this is a correct representation of what is going on inside the CPU; it's just to illustrate the
point.)

The sum "free"+"occupied" would be the "total CPU capacity", and you can determine the percentage in the way suggested by Eric.

Good luck,

Martin Schaffernicht
