Remhos (REMap High-Order Solver) is a miniapp that solves the pure advection equations that are used to perform monotonic and conservative discontinuous field interpolation (remap) as part of the Eulerian phase in Arbitrary Lagrangian Eulerian (ALE) simulations.

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

Performance Metrics

Analyze Test Configuration:

Remhos 1.0

Test: Sample Remap Example metrics for this test profile configuration based on 220 public results since 18 June 2023 with the latest data as of 28 May 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 data, the selected test / test configuration (Remhos 1.0 - Test: Sample Remap Example) 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.
