+|metric | Megabyte per second (MBps) |
+| | |
++--------------+--------------------------------------------------------------+
+|test purpose | To evaluate the IaaS compute performance with regards to |
+| | memory bandwidth. |
+| | Measure the maximum possible cache and memory performance |
+| | while reading and writing certain blocks of data (starting |
+| | from 1Kb and further in power of 2) continuously through ALU |
+| | and FPU respectively. |
+| | Measure different aspects of memory performance via synthetic|
+| | simulations. Each simulation consists of four performances |
+| | (Copy, Scale, Add, Triad). |
+| | Test results, graphs and similar shall be stored for |
+| | comparison reasons and product evolution understanding |
+| | between different OPNFV versions and/or configurations. |
+| | |
++--------------+--------------------------------------------------------------+
+|configuration | File: opnfv_yardstick_tc069.yaml |
+| | |
+| | * SLA (optional): 7000 (MBps) min_bandwidth: The minimum |
+| | amount of memory bandwidth that is accepted. |
+| | * type_id: 1 - runs a specified benchmark (by an ID number): |
+| | 1 -- INTmark [writing] 4 -- FLOATmark [writing] |
+| | 2 -- INTmark [reading] 5 -- FLOATmark [reading] |
+| | 3 -- INTmem 6 -- FLOATmem |
+| | * block_size: 64 Megabytes - the maximum block size per array|
+| | * load: 32 Gigabytes - the amount of data load per pass |
+| | * iterations: 5 - test is run 5 times iteratively. |
+| | * interval: 1 - there is 1 second delay between each |
+| | iteration. |
+| | |

+|test tool | RAMspeed |
+| | |
+| | RAMspeed is a free open source command line utility to |
+| | measure cache and memory performance of computer systems. |
+| | RAMspeed is not always part of a Linux distribution, hence it|
+| | needs to be installed in the test image. |

++--------------+--------------------------------------------------------------+
+|applicability | Test can be configured with different: |
+| | |
+| | * benchmark operations (such as INTmark [writing], |
+| | INTmark [reading], FLOATmark [writing], |
+| | FLOATmark [reading], INTmem, FLOATmem); |
+| | * block size per array; |
+| | * load per pass; |
+| | * number of batch run iterations; |
+| | * iterations and intervals. |
+| | |
+| | There are default values for each above-mentioned option. |
+| | |
++--------------+--------------------------------------------------------------+
+|pre-test | The test case image needs to be installed into Glance |
+|conditions | with RAmspeed included in the image. |
+| | |
+| | No POD specific requirements have been identified. |
+| | |
++--------------+--------------------------------------------------------------+
+|test sequence | description and expected result |
+| | |
++--------------+--------------------------------------------------------------+
+|step 1 | The host is installed as client. RAMspeed is invoked and logs|
+| | are produced and stored. |
+| | |
+| | Result: logs are stored. |
+| | |
++--------------+--------------------------------------------------------------+
+|test verdict | Test fails if the measured memory bandwidth is below the SLA |
+| | value or if there is a test case execution problem. |
