+|test purpose | The purpose of TC015 is to evaluate the IaaS compute |
+| | performance with regards to CPU processing speed with |
+| | its impact on the energy consumption |
+| | It measures score of single cpu running and parallel |
+| | running. Energy consumption and cpu load are monitored while |
+| | the cpu test is running. |
+| | |
+| | The purpose is also to be able to spot the trends. |
+| | Test results, graphs and similar shall be stored for |
+| | comparison reasons and product evolution understanding |
+| | between different OPNFV versions and/or configurations, |
+| | different server types. |
+| | |
++--------------+--------------------------------------------------------------+
+|test tool | UnixBench |
+| | |
+| | Unixbench is the most used CPU benchmarking software tool. |
+| | It can measure the performance of bash scripts, CPUs in |
+| | multithreading and single threading. It can also measure the |
+| | performance for parallel tasks. Also, specific disk IO for |
+| | small and large files are performed. You can use it to |
+| | measure either linux dedicated servers and linux vps |
+| | servers, running CentOS, Debian, Ubuntu, Fedora and other |
+| | distros. |
+| | |
+| | (UnixBench is not always part of a Linux distribution, hence |
+| | it needs to be installed. As an example see the |
+| | /yardstick/tools/ directory for how to generate a Linux |
+| | image with UnixBench included.) |
+| | |
+| | Redfish API |
+| | This HTTPS interface is provided by BMC of every telco grade |
+| | server. Is is a standard interface. |
+| | |
++--------------+--------------------------------------------------------------+
+|test | The UnixBench runs system benchmarks on a compute, getting |
+|description | information on the CPUs in the system. If the system has |
+| | more than one CPU, the tests will be run twice -- once with |
+| | a single copy of each test running at once, and once with N |
+| | N copies, where N is the number of CPUs. |
+| | |
+| | UnixBench will process a set of results from a single test |
+| | by averaging the individual pass results into a single final |
+| | value. |
+| | |
+| | While the cpu test is running Energy scenario run in |
+| | background to monitor the number of watt consumed by the |
+| | compute server on the fly. The same is done using Cpuload |
+| | scenario to monitor the overall percentage of CPU used on |
+| | the fly. This enables to balance the CPU score with its |
+| | impact on energy consumption. Synchronized measurements |
+| | enables to look at any relation between CPU load and energy |
+| | consumption. |
+| | |
++--------------+--------------------------------------------------------------+
+|configuration | file: opnfv_yardstick_tc015.yaml |
+| | |
+| | run_mode: |
+| | Run Energy and Cpuload in background |
+| | Run unixbench in quiet mode or verbose mode |
+| | test_type: dhry2reg, whetstone and so on |
+| | |
+| | Duration and Interval are set globally for Energy and |
+| | Cpuload, aligned with duration of UnixBench test. |
+| | SLA can be set for each scenario type. Default is NA. |
+| | For SLA with single_score and parallel_score, both can be |
+| | set by user, default is NA. |
+| | |
++--------------+--------------------------------------------------------------+
+|applicability | Test shall be applied to node context only |
+| | It can be configured with different: |
+| | |
+| | * test types: dhry2reg, whetstone |
+| | |
+| | Default values exist. |
+| | |
+| | SLA (optional) : min_score: The minimun UnixBench score that |
+| | is accepted. |
+| | |
++--------------+--------------------------------------------------------------+
+|usability | This test case is one of Yardstick's generic test. Thus it |
+| | is runnable on most of the scenarios. |

+|pre-test | The target shall have unixbench installed on it. |
+|conditions | |

++--------------+--------------------------------------------------------------+
+|test sequence | description and expected result |
+| | |
++--------------+--------------------------------------------------------------+
+|step 1 | Yardstick is connected with the target node using ssh. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 2 | Energy and Cpuload are launched silently in background one |
+| | after the other. |
+| | Then UnixBench is invoked. All the tests are executed using |
+| | the "Run" script in the top-level of UnixBench directory. |
+| | The "Run" script will run a standard "index" test, and save |
+| | the report in the "results" directory. Then the report is |
+| | processed by "unixbench_benchmark" and checked against the |
+| | SLA. |
+| | While unibench runs energy and cpu load are catched |
+| | periodically according to interval value. |
+| | |
+| | Result: Logs are stored. |
+| | |
++--------------+--------------------------------------------------------------+
+|test verdict | Fails only if SLA is not passed, or if there is a test case |
+| | execution problem. |
