NAS Parallel Benchmarks

NPB, NAS Parallel Benchmarks, is a benchmark developed by NASA for high-end computer systems. This test profile currently uses the OpenMP version of NPB.

Learn more about this test at the upstream project site: http://www.nas.nasa.gov/Resources/Software/npb.html.

This benchmark test profile is maintained by Michael Larabel. This OpenBenchmarking.org test profile was created on 6 December 2010 and last updated on 7 March 2020. To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark npb.

This test has an average install time of 12 seconds and an average run-time of 2 minutes, 32 seconds.

Revision History

pts/npb-1.4.1   [View Source]   07 Mar 2020 12:22 EST
Add --alow-run-as-root, ended up being missed until now.

pts/npb-1.4.0   [View Source]   28 Aug 2019 11:43 EDT
Update against upstream NPB 3.4, add new test cases.

pts/npb-1.3.1   [View Source]   15 Jan 2019 11:37 EST
Update against upstream NPB 3.1.1

pts/npb-1.3.0   [View Source]   09 Nov 2018 12:39 EST
Use physical core count rather than logical cores to avoid MPI breaking on high core count systems with SMT.

pts/npb-1.2.4   [View Source]   09 Sep 2017 10:30 EDT
ft.B not ft.C size

pts/npb-1.2.3   [View Source]   09 Sep 2017 10:15 EDT
Update MPI handling, add some larger test sizes

pts/npb-1.2.2   [View Source]   25 Aug 2016 13:51 EDT
Update CFLAGS handling

pts/npb-1.2.1   [View Source]   27 Nov 2014 18:42 EST
MG.B and IS.D do not build / run properly on modern systems.

pts/npb-1.2.0   [View Source]   05 Nov 2013 22:57 EST
Working on new version of NPB test that makes use of some of the HPCC test profile MPI improvements and other multi-core/cluster work for better benchmarking. Seems to have MPI rank errors right now though for NPB on this build.

pts/npb-1.1.1   [View Source]   10 Jun 2012 19:11 EDT
Remove tests not in MPI NPB version.

pts/npb-1.1.0   [View Source]   10 Jun 2012 16:56 EDT
Switch to the MPI version of NPB benchmarks.

pts/npb-1.0.0   [View Source]   06 Dec 2010 15:00 EST
Initial import into OpenBenchmarking.org

Analyze Test Configuration:

NAS Parallel Benchmarks 3.4

Test / Class: BT.C

OpenBenchmarking.org metrics for this test profile configuration based on 660 public samples since 28 August 2019 with the latest data as of 19 October 2020.

Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.

Based on OpenBenchmarking.org data, the selected test / test configuration (NAS Parallel Benchmarks 3.4 - Test / Class: BT.C) has an average run-time of 8 minutes. By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result.
