VkFFT

VkFFT is a Fast Fourier Transform (FFT) Library that is GPU accelerated by means of the Vulkan API. The VkFFT benchmark runs FFT performance differences of many different sizes before returning an overall benchmark score.

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

Performance Metrics

Analyze Test Configuration:

VkFFT 2020-09-29

OpenBenchmarking.org metrics for this test profile configuration based on 326 public results since 29 September 2020 with the latest data as of 31 January 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 (VkFFT 2020-09-29) has an average run-time of 6 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.
