NAMD

NAMD is a parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems. NAMD was developed by the Theoretical and Computational Biophysics Group in the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign.

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

Performance Metrics

Analyze Test Configuration:

NAMD 3.0b6

Input: ATPase with 327,506 Atoms

OpenBenchmarking.org metrics for this test profile configuration based on 141 public results since 16 February 2024 with the latest data as of 28 February 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 (NAMD 3.0b6 - Input: ATPase with 327,506 Atoms) has an average run-time of 3 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.
