Abstract

I will talk about the ExCALIBUR H&ES project benchmarking for performance portable applications and demonstrate some envisioned use cases. Application benchmarking is a crucial activity in the path to Exascale. It ensures future systems are understood by the community so that science applications, can take advantage of the opportunities at Exascale. Benchmarking commonly requires manual work and relies on knowledge possessed by a few individuals. We want to provide tools to rigorously measure the performance of benchmarks in a systematic way to enhance the transparency and enable reproducibility. The goal of this project is to provide the tooling to automate collecting and analysing benchmark data. It provides a framework for building and running benchmarks in diverse architectures and post-processing the results, a community-driven collection of scientific benchmarks, as well as guidance for contributing benchmark applications and system configuration.

Hybrid Zoom details will be emailed to the RSE mailing list; if you are not on the list, please contact the organisers.
