Performance Metrics

Analyze Test Configuration:

OpenDwarfs 2013-11-06

Test: LU Decomposition metrics for this test profile configuration based on 101 public results since 6 November 2013 with the latest data as of 2 November 2015.

Additional benchmark metrics will come after has collected a sufficient data-set.

Based on data, the selected test / test configuration (OpenDwarfs 2013-11-06 - Test: LU Decomposition) 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.
