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.
The Center for Computational Research (CCR) at the University at Buffalo has developed Grendel: a fast, easy to use, bare metal provisioning system for High Performance Computing (HPC). Grendel simplifies network booting racks of compute nodes by providing a robust PXE boot server, rest API, and node management in a single binary for easy installation. In this paper, we describe CCR's HPC network architecture and how Grendel was used to provision the center's Linux based compute clusters. We also present some modern features built into Grendel including automatic host discovery, deploying Live OS images to bare metal compute nodes, and delivering kernel, initramfs, and other provisioning assets using access tokens and trusted HTTPS.
