- # Name Of File: run_cpuctl_test.sh #
- # #
- # Description: This file runs the setup for testing diff cpucontroller feature. #
- # After setup it runs diff test cases in diff setup. #
- # #
- # Test 01: Tests fairness with respect to absolute share values #
- # Test 02: Tests if fairness persists among different runs #
- # Test 03: Granularity test with respect to shares values #
- # Test 04: Nice value effect on group scheduling #
- # Test 05: Task migration test #
- # #
- # Precaution: Avoid system use by other applications/users to get fair and #
- # appropriate results #
