  THE RESOURCE MANAGEMENT (CONTROLLERS) TEST PLAN
  
! This directory "controllers" is created to include all test cases related to the resource
! controllers in linux. The testplan at present includes testing of cpu controller and memory
! controller. This is the first testcase in LTP to test the resource controllers (and tests
! cpu controller only). Future testcases willl be included to test the cpu controller further
! and memory controller. Each controller will have it's own directory to contain all test cases.
  
  
  For more information on resource controllers please refer to cgroups.txt in kernel documentation.

! CPU CONTROLLER:
! ==============
! 
! Test 01:
  
+ The aim of the test is to find any dependency of cpu controller on exact value
+ of shares to schedule the tasks. For example if there are two groups running
+ 1 task each then they must get the cpu time in the same ratio irrespective of
+ the share values i.e. share ratios 1:2, 10:20, 100:200, 1000:2000 etc should
+ give the same cpu usage for each group.
