+|test purpose  | To evaluate the IaaS compute capability with regards to      |
+|              | memory utilization.This test case should be run in parallel  |
+|              | to other Yardstick test cases and not run as a stand-alone   |
+|              | test case.                                                   |
+|              | Measure the memory usage statistics including used memory,   |
+|              | free memory, buffer, cache and shared memory.                |
+|              | Both average and maximun values are obtained.                |
+|              | The purpose is also to be able to spot trends.               |
+|              | Test results, graphs and similar shall be stored for         |
