2.16.2.34. Yardstick Test Case Description TC084

Compute Performance
test case id OPNFV_YARDSTICK_TC084_SPEC CPU 2006 FOR VM
metric compute-intensive performance
test purpose The purpose of TC084 is to evaluate the IaaS compute performance by using SPEC CPU 2006 benchmark. The SPEC CPU 2006 benchmark has several different ways to measure computer performance. One way is to measure how fast the computer completes a single task; this is called a speed measurement. Another way is to measure how many tasks computer can accomplish in a certain amount of time; this is called a throughput, capacity or rate measurement.
test tool

SPEC CPU 2006

The SPEC CPU 2006 benchmark is SPEC’s industry-standardized, CPU-intensive benchmark suite, stressing a system’s processor, memory subsystem and compiler. This benchmark suite includes the SPECint benchmarks and the SPECfp benchmarks. The SPECint 2006 benchmark contains 12 different benchmark tests and the SPECfp 2006 benchmark contains 19 different benchmark tests.

SPEC CPU 2006 is not always part of a Linux distribution. SPEC requires that users purchase a license and agree with their terms and conditions. For this test case, users must manually download cpu2006-1.2.iso from the SPEC website and save it under the yardstick/resources folder (e.g. /home/ opnfv/repos/yardstick/yardstick/resources/cpu2006-1.2.iso) SPEC CPU® 2006 benchmark is available for purchase via the SPEC order form (https://www.spec.org/order.html).

test description This test case uses SPEC CPU 2006 benchmark to measure compute-intensive performance of VMs.
configuration

file: opnfv_yardstick_tc084.yaml

benchmark_subset is set to int.

SLA is not available in this test case.

applicability

Test can be configured with different:

  • benchmark_subset - a subset of SPEC CPU 2006 benchmarks to run;
  • SPECint_benchmark - a SPECint benchmark to run;
  • SPECint_benchmark - a SPECfp benchmark to run;
  • output_format - desired report format;
  • runspec_config - SPEC CPU 2006 config file provided to the runspec binary;
  • runspec_iterations - the number of benchmark iterations to execute. For a reportable run, must be 3;
  • runspec_tune - tuning to use (base, peak, or all). For a reportable run, must be either base or all. Reportable runs do base first, then (optionally) peak;
  • runspec_size - size of input data to run (test, train, or ref). Reportable runs ensure that your binaries can produce correct results with the test and train workloads
usability This test case is used for executing SPEC CPU 2006 benchmark on virtual machines. The SPECint 2006 benchmark takes approximately 5 hours. (The time may vary due to different VM cpu configurations)

pre-test conditions

To run and install SPEC CPU 2006, the following are required:

  • For SPECint 2006: Both C99 and C++98 compilers are installed in VM images;
  • For SPECfp 2006: All three of C99, C++98 and Fortran-95 compilers installed in VM images;
  • At least 4GB of disk space availabile on VM.

gcc 4.8.* and g++ 4.8.* version have been tested in Ubuntu 14.04, Ubuntu 16.04 and Redhat Enterprise Linux 7.4 image. Higher gcc and g++ version may cause compiling error.

test sequence description and expected result
step 1 cpu2006-1.2.iso has been saved under the yardstick/resources folder (e.g. /home/opnfv/repos/yardstick/yardstick/resources /cpu2006-1.2.iso). Additionally, to use your custom runspec config file you can save it under the yardstick/resources/ files folder and specify the config file name in the runspec_config parameter.
step 2 Upload SPEC CPU 2006 ISO to the target VM using scp and install SPEC CPU 2006.
step 3 Connect to the target server using SSH. If custom runspec config file is used, copy this file from yardstick to the target VM via the SSH tunnel.
step 4 SPEC CPU 2006 benchmark is invoked and SPEC CPU 2006 metrics are generated.
step 5 Text, HTML, CSV, PDF, and Configuration file outputs for the SPEC CPU 2006 metrics are fetched from the VM and stored under /tmp/result folder.
test verdict None. SPEC CPU 2006 results are collected and stored.
