Performance Metrics

Analyze Test Configuration:

LeelaChessZero 0.31.1

Backend: Eigen

OpenBenchmarking.org metrics for this test profile configuration based on 63 public results since 11 August 2024 with the latest data as of 14 August 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 (LeelaChessZero 0.31.1 - Backend: Eigen) has an average run-time of 28 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 0.2%.
