Argonne Selects Altair Workload Manager for Polaris, Aurora

Simulation software company Altair has announced that Argonne National Laboratory will utilize Altair PBS Professional workload manager across the organization’s HPC systems at the Argonne Leadership Computing Facility (ALCF)  – including the Polaris and Aurora supercomputers – to accelerate research in science and engineering.

PBS Professional – which replaces the ALCF’s in-house Cobalt workload manager – will be the default workload management solution and job scheduler and is designed to allow researchers to more easily and efficiently run diverse workloads, including machine learning and data-intensive tasks, as well as traditional simulations.

With Polaris as a testbed system for the Aurora exascale system (capable of performing a quintillion calculations per second), Argonne said it’s critical “to ensure that downtime is avoided as it could put research teams hundreds of hours behind completing a project. Supported by Altair’s global team of HPC specialists, PBS Professional will optimize and manage thousands of node hours simultaneously and will help ensure that researchers using the ALCF can make quicker, more efficient scientific discoveries.”

“We explored many options when we were looking for a workload manager to replace our in-house Cobalt scheduler,” said Bill Allcock, manager of ALCF’s advanced integration group. “With Altair and PBS Professional we found an open and established mechanism for accepting contributions, with a long-term roadmap that is well aligned with our own. Altair’s PBS Professional will help compute-intensive research campaigns that will be running on our next-generation supercomputers.”

ALCF said that In 2020, it served more than 100 million node hours of compute time. PBS Professional’s multi-dimensional workload orchestration capabilities will now support the ALCF’s exploration of cancer treatments, clean energy, particle collision research, and more. It will also help researchers:

  • Advance our understanding of the universe – Researchers will carry out large-scale, high-resolution simulations of the universe to help guide and interpret observations from upcoming sky surveys, providing insights into mysterious cosmological phenomena, such as dark matter and dark energy.
  • Design more efficient aircraft – Researchers will perform massive computational fluid dynamics simulations to explore how turbulent flows impact aircraft performance, generating data that can help inform the design of more fuel-efficient airplanes.
  • Improve solar power technology – Researchers will combine simulation, data science, and machine learning techniques on ALCF’s next-generation systems to revolutionize the computational discovery of new materials for more efficient organic solar cells.
  • Predict drug responses virtually – Researchers will screen billions of virtual drugs while predicting their effects on tumor cells. This approach aims to dramatically accelerate successful drug development and provide new approaches to personalized cancer medicine.

“Exascale computing will open new pathways of discovery and transform how researchers tackle some of the world’s most important challenges. Altair is proud to provide scalability fit for exascale computing and to help Argonne’s scientific user community accelerate their groundbreaking work,” said James R. Scapa, founder and chief executive officer, Altair. “PBS Professional is a proven, powerful, secure, and trusted enterprise-level solution designed to improve productivity, optimize utilization and efficiency, and simplify administration for clusters, clouds, and supercomputers.”

In addition to ALCF’s adoption of PBS Professional, the workload manager and job scheduler will be an available resource for all the lab’s HPC systems and clusters.
