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. | +| | | ++--------------+--------------------------------------------------------------+ +|references | RAMspeed_ | +| | | +| | ETSI-NFV-TST001 | +| | | ++--------------+--------------------------------------------------------------+ +|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.
