-|test case id | OPNFV_YARDSTICK_TC069_Memory Bandwidth |
-| | |
-+--------------+--------------------------------------------------------------+
-|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. |
