NAS Parallel Benchmarks

NPB, NAS Parallel Benchmarks, is a benchmark developed by NASA for high-end computer systems. This test profile currently uses the MPI version of NPB. This test profile offers selecting the different NPB tests/problems and varying problem sizes.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark npb.

Use physical core count rather than logical cores to avoid MPI breaking on high core count systems with SMT.

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]   Sun, 10 Jun 2012 19:11:43 GMT
Remove tests not in MPI NPB version.

Performance Metrics

Analyze Test Configuration:

NAS Parallel Benchmarks 3.4

Test / Class: LU.C

OpenBenchmarking.org metrics for this test profile configuration based on 1,063 public results since 28 August 2019 with the latest data as of 10 April 2021.

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: LU.C) has an average run-time of 5 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.

Does It Scale Well With Increasing Cores?

Yes, based on the automated analysis of the collected public benchmark data, this test / test settings does generally scale well with increasing CPU core counts. Data based on publicly available results for this test / test settings, separated by vendor, result divided by the reference CPU clock speed, grouped by matching physical CPU core count, and normalized against the smallest core count tested from each vendor for each CPU having a sufficient number of test samples and statistically significant data.
