1624 | giacomo | 1 | FSF demo for S.Ha.R.K |
2 | |||
3 | test1.c: |
||
4 | |||
5 | This demo shows the main feature of service contract implementation. |
||
6 | |||
7 | A set of 4 threads is created using the pthread standard functions. |
||
8 | At the beginning, these threads run without temporal restrictions |
||
9 | and they don't respect any deadline. |
||
10 | |||
11 | Two service contracts are initialized and set |
||
12 | |||
13 | fsf_initialize_contract(&contract1); |
||
14 | fsf_initialize_contract(&contract2); |
||
15 | fsf_set_contract_basic_parameters(&contract1,&budget1,&period1,NULL,NULL,FSF_DEFAULT_WORKLOAD); |
||
16 | fsf_set_contract_basic_parameters(&contract2,&budget2,&period2,NULL,NULL,FSF_DEFAULT_WORKLOAD); |
||
17 | |||
18 | whit the button 'q','w','e' you can respectively |
||
19 | negotiate contract for a server |
||
20 | |||
21 | [err = fsf_negotiate_contract(&contractX,&serverY);] |
||
22 | |||
23 | 'q' -> negotiate contract1 for server1 |
||
24 | 'w' -> negotiate contract2 for server2 |
||
25 | 'e' -> negotiate contract1 for server3 |
||
26 | |||
27 | now with button '1','2','3','4' you can bind the thread to a server |
||
28 | |||
29 | [err = fsf_bind_thread_to_server(serverY,jZ);] |
||
30 | |||
31 | '1' -> bind thread1 to server1 |
||
32 | '2' -> bind thread2 to server2 |
||
33 | '3' -> bind thread3 to server3 |
||
34 | '4' -> bind thread4 to server2 |
||
35 | |||
36 | threads will start to respect the assigned budget. It's possible |
||
37 | to bind more threads to one server. The local scheduler specified in the |
||
38 | contract define how the threads will get the server resources. |
||
39 | |||
40 | With '5','6','7','8' the thread is unbind from the server |
||
41 | |||
42 | [err = fsf_unbind_thread_from_server(jZ);] |
||
43 | |||
44 | With 'r','t','y' a server is removed |
||
45 | |||
46 | [err = fsf_cancel_contract(&server2);] |
||
47 | |||
