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.
* Uploading of benchmark result data to OpenBenchmarking.org is always optional (opt-in) via the Phoronix Test Suite for users wishing to share their results publicly. ** Data based on those opting to upload their test results to OpenBenchmarking.org and users enabling the opt-in anonymous statistics reporting while running benchmarks from an Internet-connected platform. *** Test profile page view reporting began March 2021. Data updated weekly as of 13 April 2024.

pts/npb-1.4.1 [View Source] Sat, 07 Mar 2020 12:22:08 GMT Add --alow-run-as-root, ended up being missed until now.
pts/npb-1.4.0 [View Source] Wed, 28 Aug 2019 11:43:04 GMT Update against upstream NPB 3.4, add new test cases.
pts/npb-1.3.1 [View Source] Tue, 15 Jan 2019 11:37:52 GMT Update against upstream NPB 3.1.1
pts/npb-1.3.0 [View Source] Fri, 09 Nov 2018 12:39:01 GMT Use physical core count rather than logical cores to avoid MPI breaking on high core count systems with SMT.
pts/npb-1.2.1 [View Source] Thu, 27 Nov 2014 18:42:33 GMT MG.B and IS.D do not build / run properly on modern systems.
pts/npb-1.2.0 [View Source] Tue, 05 Nov 2013 22:57:21 GMT 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.

OpenBenchmarking.org metrics for this test profile configuration based on 1,759 public results since 28 August 2019 with the latest data as of 18 April 2024.
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: SP.B) has an average run-time of 3 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.
Based on public OpenBenchmarking.org results, the selected test / test configuration has an average standard deviation of 0.4%.
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.
Tested CPU Architectures
This benchmark has been successfully tested on the below mentioned architectures. The CPU architectures listed is where successful OpenBenchmarking.org result uploads occurred, namely for helping to determine if a given test is compatible with various alternative CPU architectures.
