WRF

WRF, the Weather Research and Forecasting Model, is a "next-generation mesoscale numerical weather prediction system designed for both atmospheric research and operational forecasting applications. It features two dynamical cores, a data assimilation system, and a software architecture supporting parallel computation and system extensibility."

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

Performance Metrics

WRF 4.2.2

Input: conus 2.5km

OpenBenchmarking.org metrics for this test profile configuration based on 467 public results since 27 April 2021 with the latest data as of 1 December 2023.

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 (WRF 4.2.2 - Input: conus 2.5km) has an average run-time of 3 hours, 29 minutes. By default this test profile is set to run at least 1 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.
