User Managed Software

Did you know that the OLCF has a program where users can provide software for the entire user community? Please check out our current UMS projects available on the OLCF systems for recent additions including SOLLVE (Exascale OpenMP Programming Environment) and a development build of the LLVM compiler provided by users from the University of Delaware, and DPC++ for HIP provided by users from Codeplay.
The current documentation can be found here:

Center Announcements

The annual OLCF User Survey is now available

The annual OLCF User Survey is now available for your participation at the following URL:
The survey is conducted on behalf of the OLCF by Oak Ridge Associated Universities (ORAU) and should take approximately 10 minutes to complete.
Just as project reports are a requirement of all OLCF projects, participation in the annual User Survey is an important obligation and a requirement of your OLCF access.  At the OLCF, we are focused on making ongoing improvements to user satisfaction.  The OLCF relies strongly on the input received from our user community and encourages you to continue providing feedback through the annual survey and directly to our staff.  Users can also provide comments and feedback to the OLCF User Group Executive Board.  In addition, survey response is one of the key areas in which the OLCF is evaluated, and thus your participation is very important to ensure the OLCF continues to be able to provide you with leadership computing resources.
The survey is scheduled to close on November 11, 2022. If you have questions, please contact the OLCF User Assistance Center at

ALCC Call for Proposals

NOTE: Pre-proposals are due on November 28, 2022
The DOE Office of Advanced Scientific Computing Research (ASCR) is now accepting application proposals for the 2023-24 allocation year of the ASCR Leadership Computing Challenge (ALCC) program. The program provides access to computational resources at ASCR’s three supercomputing facilities (OLCF, ALCF, and NERSC) and will include allocations on OLCF’s Frontier system.
The proposal process consists of two steps, with a pre-proposal due on November 28, 2022, and the full proposal due on February 17, 2023. The allocation period for successful proposals will run from July 1, 2023-June 30, 2024.

Black Lives Count: Toward Accountability in Efforts to Diversify Computing
October 25, 1:00-2:15 pm ET

The ECP HPC Workforce Development and Retention Action Group invite you to our October Webinar, Black Lives Count: Toward Accountability in Efforts to Diversify Computing. The event will be held on Zoom October 25 from 1:00-2:15 pm ET. ECP HPC-WDR Webinars are free and open to the public, though registration is required. In April, the United States presidential administration announced a whole-of-government effort focused largely on gathering and increasing access to disaggregated data on the experiences of historically underserved groups. The importance of disaggregating the data on specific subpopulations can easily be overlooked in efforts that target diversity broadly. Drawing inspiration from astrophysics, this talk will focus on data and analyses related to the hiring of a specific population that is underrepresented in scientific research: African-American doctoral degree holders. The talk will conclude with a call for accountability through disaggregating data in diversity, equity, and inclusion (DEI) initiatives.
Speaker: Damian Rouson, Computer Languages and Systems Software Group Leader, Lawrence Berkeley National Laboratory
