Benchmarks of WRF v4.2 on Google Cloud and Cheyenne

This post was from a previous version of the WRF&MPAS-A Support Forum. New replies have been disabled and if you have follow up questions related to this post, then please start a new thread from the forum home page.

What: In this livestream, we'll share with you benchmarks of WRF v4 on Google Cloud Platform and the Cheyenne supercomputer at NCAR. Specifically, we'll look at the CONUS 2.5km and CONUS 12km benchmarks across machine types available on Google Cloud. The benchmarks are presented with both the time-to-solution and cost for running short forecasts on GCP, and we examine the impacts of these metrics on process affinity, specifically with relation to the use of hyperthreading. I'll show you a strategy to optimize file IO performance through the use of parallel file IO in WRF with a cloud-native Lustre file-system.

We welcome your comments, thoughts, questions, and feedback at this livestream! At the end of the presentation, there will be time for Q&A.
