MORB

A model order reduction benchmark (MORB) tool is currently under development. It is a demonstrator of the generic benchmark framework (MaRDIMark) developed for Task Area 2 of the Mathematical Research Data Initiative (MaRDI) and will serve as an example of how to fairly compare different implementations of algorithms across a standardized benchmark set for scientific computing.

Overview

An overview of MaRDI and MORB are provided in the poster, which was presented at Model Reduction and Surrogate Modeling (MORE), 19-23 September 2022, Berlin, Germany.

A MATLAB prototype for linear-time-invariant, first-order systems (LTI-FOS) is largely operational. An example report for the CD Player benchmark is provided.

Please also see the report published in PAMM, as well as the accompanying code hosted at Zenodo.
