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:

Meetings & Workshops

Vampir and Score-P Training
Monday, November 6, 2023

9:00 AM – 12:00 PM (EST)
Wednesday, November 8, 2023
9:00 AM – 12:00 PM (EST)

Vampir is an established performance tool for visualizing and analyzing the behavior of highly parallel HPC applications. It is supported by the Score-P tool, which can be used to fully record the runtime behavior of HPC applications. Especially when using several parallel programming paradigms or shared HPC resources (I/O), this offers a detailed insight into the application. This workshop introduces the use of Vampir and Score-P for the interactive and visual analysis of the runtime behavior of HPC applications. Day one will feature lessons and hands-on exercises. The second day will give users an opportunity to bring their own codes and instrument them for performance analysis with help from Score-P and Vampir developers. To take advantage of this you must have a code that is already compiled and working on Frontier.
