HeFFTe - Highly Efficient FFT for Exascale

HeFFTe is the Highly Efficient FFT for Exascale software developed as part of the Exascale Computing Project. This test profile uses HeFFTe's built-in speed benchmarks under a variety of configuration options and currently catering to CPU/processor testing.

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

Performance Metrics

HeFFTe - Highly Efficient FFT for Exascale 2.4

Test: r2c - Backend: FFTW - Precision: float - X Y Z: 128

OpenBenchmarking.org metrics for this test profile configuration based on 107 public results since 27 October 2023 with the latest data as of 23 May 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 (HeFFTe - Highly Efficient FFT for Exascale 2.4 - Test: r2c - Backend: FFTW - Precision: float - X Y Z: 128) has an average run-time of 2 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 1.4%.
