24# Description: This file runs the setup for testing diff cpucontroller feature. #
25#              After setup it runs diff test cases in diff setup.               #
26#                                                                               #
27# Test 01:     Tests fairness with respect to absolute share values             #
28# Test 02:     Tests if fairness persists among different runs                  #
29# Test 03:     Granularity test with respect to shares values                   #
30# Test 04:     Nice value effect on group scheduling                            #
31# Test 05:     Task migration test                                              #
32#                                                                               #
