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. 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. | | | | +--------------+--------------------------------------------------------------+ ..
