Sample Pi Program

A simple C++ program that calculates Pi to 8,765,4321 digits using the Leibniz formula. This test can be used for showcasing how to write a basic test profile.

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

Use with caution this test profile is currently marked Experimental.

Performance Metrics

Sample Pi Program

OpenBenchmarking.org metrics for this test profile configuration based on 706 public results since 26 October 2017 with the latest data as of 13 February 2025.

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 (Sample Pi Program) 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 0.5%.
