Performance Metrics

Analyze Test Configuration:

CUDA Mini-Nbody 2015-11-10

Test: Original

OpenBenchmarking.org metrics for this test profile configuration based on 373 public results since 7 December 2018 with the latest data as of 29 April 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.
