Upcoming Downtimes

  • Slate’s Marble cluster will be upgraded to OpenShift 4.11 starting at 8:00 AM on January 30th through 8:00 AM on February 1st. The Marble cluster should remain available for use during this time, but workloads will migrate around the cluster as needed to accommodate node upgrades. There should be no API changes with this upgrade that would impact running workloads; however, the API server may be unavailable at times during the process. In addition, the NVIDIA driver will be upgraded to version 535.129.03 along with CUDA version 12.2. Please make note of these changes as they may require a change to your GPU application workloads.

Call for Abstracts for Quantum Computing User Forum

The Quantum Computing User Forum will be held August 12-15, 2024 in Oak Ridge, TN. The forum serves to foster engagement between users, vendors, and subject matter experts from national laboratories, industry, and academia. The agenda will consist of invited and contributed talks from the diversity of users represented by the Quantum Computing User Program (QCUP). A summary of last year’s event is available online. The call for abstracts for contributed talks and posters is now open.

All QCUP users are eligible to submit before the deadline of March 15, 2024. Submissions must indicate the QCUP project ID and abstract summary to be considered. Additional online information may be submitted by providing the DOI number, e.g., from publication or pre-print server. Additional inquiries may be submitted to the Quantum Computing User Program administration team by emailing

Frontier and Crusher System Update
On Tuesday, January 23, 2024, Frontier and Crusher were upgraded to a new version of the AMD GPU driver. In addition, ROCm 6.0.0 and HPE/Cray PE 23.12 were made available. For more information, please see the “System Updates” sections in the Frontier and Crusher user guides.

Meetings & Workshops

March Frontier Hackathon
Application Deadline February 4

February HPC-Workforce Webinar: HPC Culture and Identity
Virtual via Zoom
​February 15, 2023, 2:00 PM -3:00 PM (ET)

The HPC Workforce Development and Retention action group will host Dr. Denice Ward Hood, Director of the Center for Culturally Responsive Evaluation and Assessment (CREA) at the University of Illinois, to give a webinar on HPC Culture and Identity. Issues and questions to be addressed in HPC are sufficiently complex and nuanced so that multiple perspectives, world views and lived experiences are needed to adequately attend to them. HPC is attractive as a field because it appeals to individuals’ unique curiosity, skills, and aptitude. Your whole, authentic self is an asset and a source of innovation. This talk with be a space for discussion about culture and identities and the ways in which they inform and guide our work.
