Weather and climate centers worldwide rely on the power of high-performance computing (HPC), and Altair keeps HPC running reliably and efficiently. Because modeling the Earth’s weather and climate is a challenge, it requires powerful HPC systems and software that can orchestrate the most complex workloads. Fields such as climate modeling and numerical weather forecasting have global economic and social impact.
How to choose the right material, the right design, and the right process to develop solutions that minimize carbon emissions and bolster your bottom line.
A step-by-step guide for transforming your plastics engineering value chain to develop solutions that optimize performance, minimize carbon emissions, and gain a competitive edge.
What you will learn:
Weather and climate centers worldwide rely on the power of high-performance computing (HPC) to track, analyze, simulate and predict the behavior of weather systems, climate patterns and other atmospheric phenomena. In this roundtable, experts from leading weather and climate centers across the globe will detail how they harness HPC to fuel this critically important research.
Topics will include:
HPC systems at NCAR power the science behind global weather and climate prediction and research. In early 2021, NCAR announced that their Cheyenne supercomputer, located at the NCAR-Wyoming Supercomputing Center, will be replaced by a new HPE Cray EX system with 3.5x more processing power, up to 19.87 petaflops with a combination of CPU and GPU nodes. The new system will include efficient workload management and scheduling by Altair® PBS Professional® and Altair Accelerator™ Plus.
Computational and Information Systems Laboratory (CISL) supports and advances this research in the geosciences with the world-class HPC and high-performance storage. For workload management and resource scheduling, NCAR uses Altair PBS Professional to exploit features like cloud bursting, fairshare, power-user and maintenance reservations, resource assignment with control groups, high-throughput hierarchical scheduling, green provisioning, and energy-aware scheduling. This presentation by Irfan Elahi, Brian Vanderwende, and John Blaas from the National Center for Atmospheric Research (NCAR) was aired during the 2021 Altair HPC Summit, and is about 29 minutes long.
