PEARC20 has ended
Welcome to PEARC20!
PEARC20’s theme is “Catch the Wave.” This year’s theme embodies the spirit of the community’s drive to stay on pace and in front of all the new waves in technology, analytics, and a globally connected and diverse workforce. We look forward to this year’s PEARC20 virtual meeting, where we can share scientific discovery and craft the future infrastructure.

The conference will be held in Pacific Time (PT) and the times listed below are in Pacific Time.

The connection information for all PEARC20 workshops, tutorials, plenaries, track presentations, BOFs, Posters, Visualization Showcase, and other affiliated events, are in the PEARC20 virtual conference platform, Brella. If you have issues joining Brella, please email pearcinfo@googlegroups.com.

Frontera: The Evolution of Leadership Computing at the National Science Foundation

As part of the NSF's cyberinfrastructure vision for a robust mix of high capability and capacity HPC systems, Frontera represents the most recent evolution of trans-petascale resources available to all open science research projects in the U.S. Debuting as the fifth largest supercomputer in the world, Frontera represents a robust and well-balanced HPC system designed to enable large-scale, productive science on day one of operations. The system provides a primary compute capability of nearly 39PF, delivered completely via more than 8,000 dual-socket servers with conventional Intel 8280 ("Cascade Lake") processors. A unique configuration of both desktop GPUs and advanced floating units from NVIDIA enables both machine learning and scientific workloads, and the system delivers nearly 2TB/s of total filesystem bandwidth with 55 PB of usable Lustre disk-based storage and 3PB of all flash Lustre storage. A Mellanox InfiniBand (IB) interconnect provides very low latency with 100Gbps to each node, and 200Gbps between switches in a fat tree topology with minimal oversubscription for efficient communication, even in jobs that use the full system with complex communication patterns. The system hardware is complemented by a robust set of software services, including Application Programmer Interfaces (APIs) to support an evolving user base that increasingly demands productive access via science gateways and automated workflows, as well as a first-of-its-kind partnership with the three major cloud service providers to create a bridge between "traditional" HPC and the cloud infrastructure upon which research increasingly depends.
