39 | Test Number 13 (D): |
||
40 | |||
41 | this is a part of the classic Hartik demo Aster, and it is based on aster 3. |
||
42 | |||
43 | The demo creates: |
||
44 | - a set of TBS tasks assigned to 2 TBS servers initialized with different bandwidth. |
||
45 | |||
46 | - a set of periodic tasks, just to make noise (function asteroide) |
||
47 | |||
48 | - a set of CBS tasks that are created to fill the available free |
||
49 | bandwidth (function soft_aster) |
||
50 | |||
51 | - a few service task (the one that creates the CBS tasks (aster), a clock, |
||
52 | JET info visualization |
||
53 | |||
54 | - a set of never ending "system tasks" that simulate a device driver |
||
55 | task that will end only at shutdown (function aper_asteroid) |
||
56 | |||
57 | - a keyboard task that will execute an hook to terminate the system |
||
