39 | Test for Sporadic Server (ss): |
||
40 | |||
41 | this is a part of the classic Hartik demo Aster. |
||
42 | |||
43 | it is based on test 17 (h), and the JobControl Task uses an |
||
44 | SOFT_TASK_MODEL served by a sporadic server |
||
45 | There are two "dummy" tasks that increment a counter and print |
||
46 | the value. One uses a SOFT_TASK_MODEL served by sporadic server, |
||
47 | the other uses a NRT_TASK_MODEL handled by RR module. |
