New Data Analysis Cluster: Andes
As announced during the recent OLCF User Meeting, we will soon replace our data analysis cluster Rhea with a new system named Andes. Andes will contain 704 compute nodes, each with two 16-core AMD EPYC processors and 256 GB of memory. Additionally, the GPU/High-Memory nodes currently in Rhea’s ‘rhea-gpu’ partition will be moved over to Andes.

The availability timeline will be announced in future user messages. In the meantime, we suggest users begin reviewing the Andes User Guide located at If you have any questions, please contact the User Assistance Center at

Tour the OLCF (Virtually)
Want to tour the OLCF even though you can’t travel here? Now you can! OLCF used Matterport to create a virtual walkthrough of the center. To view the tour, visit

Meetings & Workshops

CUDA Training Series
NVIDIA will present a 9-part CUDA training series intended to help new and existing GPU programmers understand the main concepts of the CUDA platform and its programming model. Each part will include a 1-hour presentation and example exercises. The exercises are meant to reinforce the material from the presentation and can be completed during a 1-hour hands-on session following each lecture. The full list of topics can be found on the series page. If you have any questions about this series, please contact Tom Papatheodore. The final session, Cooperative Groups, will be held on Thursday, September 17.

Introduction to Deep Learning for Scientific Applications (Oct 7-8)
The OLCF, in conjunction with IBM, will host a 2-day (virtual) training to help current Summit users understand how they might use machine learning (ML) / deep learning (DL) in their traditional (modeling and simulation) scientific applications. The content will begin with an introduction to basic ML/DL concepts and work toward an understanding of how DL surrogates can be integrated into larger applications. This material will be delivered through a combination of presentations and hands-on labs. For more information, or to register, please visit

Upcoming Scheduled Outages

Work will be performed on Marble from 8:00 AM to noon on Tuesday, September 15. Workflows should migrate between servers within the cluster so no user impact is anticipated.

All compute systems, the Data Transfer Nodes, the Alpine filesystem and HPSS will be unavailable from 8:00 AM until 4:00 PM on Tuesday, September 15.
