Performance Metrics

Analyze Test Configuration:

CUDA Mini-Nbody 2015-11-10

Test: Original

OpenBenchmarking.org metrics for this test profile configuration based on 1,495 public results since 7 December 2018 with the latest data as of 1 March 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.
