# 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 #
