Alpine Filesystem Decommission in 12-Weeks (Dec 31)

The Alpine filesystem will be decommissioned in 12 weeks.  Data remaining on Alpine will be permanently deleted on January 01, 2024.  We strongly urge you to begin migrating any needed data now.

More details on the Alpine decommission timeline can be found at

Call for Proposals for Summit in 2024

The Department of Energy is extending Summit operations through October 2024, enabling researchers to pursue projects on one of the world’s leading AI-enabled open science supercomputing platforms.  OLCF will allocate Summit through new programs for the calendar year 2024.  SummitPLUS is one of the new allocation programs that will be used to allocate a significant portion of the system for 2024. The program is open to researchers from academia, government laboratories, federal agencies, and industry. We welcome proposals for computationally ready projects from investigators who are new to Summit, as well as from previous INCITE, ALCC, DD, ECP awardees and projects. We encourage proposals on emerging paradigms for computational campaigns including data-intensive science and AI/ML.

More information on the SummitPLUS allocation program and Alpine decommission can be found at

The annual OLCF User Survey is now available

The annual OLCF User Survey is now open. The survey is conducted on behalf of the OLCF by Oak Ridge Associated Universities (ORAU) and should take approximately 10 minutes to complete. We truly value your feedback and encourage all users to complete this important survey to help us know how to better serve our user community. The survey closes on November 20, 2023.

ALCC Pre-Proposals due Nov. 13

The ASCR Leadership Computing Challenge (ALCC) is an allocation program for projects of interest to the DOE, with an emphasis on high-risk, high-payoff scientific campaigns enabled by HPC.  The ALCC is currently soliciting proposals for allocation awards for the 2024-2025 allocation year.  For more information please see:
