Description:
The CPU application is a very simple one and consists of just one window.
Accordingly, this window will be called "CPU window" in the following.
It kind of represents a thread in the system that's only active if no other thread
is ready to run.
This special thread is called the "idle thread".
It is easy to understand that if the idle thread is active very often, the load of
the system is very low.
If the idle thread is only rarely active, many other threads
occupy and consume the available computation power.
The system is heavily loaded then.
The CPU application displays these changing activities throughout the system.
Its three different colors are just meant to visualize low (green), medium (yellow)
and heavy (red) load of the system.
As these three colors are always visible you have to watch out if they are lighted.
Only the area of light green/yellow/red shows the actual system load.
For example in the CPU window screenshot (top right) only a part of the green area
is lighted.
This shows very little load.
The scale is to be read vertically and linear.
If you move the mouse cursor rapidly, for example, you can provoke a reaction in the
CPU window.
You will then be able to watch a little more activity displayed.
Operating:
The CPU application is a non-interactive displaying application and can therefore only be
started and killed.
