Save the date: 2024 OLCF User Meeting

The OLCF will hold its annual User Meeting September 10-11, 2024. The 2024 meeting will feature OLCF facility updates, user-experience talks from teams running on Frontier, and deep dive discussions with OLCF staff. This year, we would like to invite users to participate by submitting a poster or a talk to be presented at the meeting. To learn more and to register, please see:

INCITE 2025 Call for Proposals

The U.S. Department of Energy’s (DOE) Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program is now accepting proposals for high-impact, computationally intensive research projects in a broad array of science, engineering and computer science domains. Proposals must be submitted between April 10 and June 14, 2024.

Meetings & Workshops ​

OLCF OpenMP Training series Office Hour
May 16, 1:00-2:00 EDT.

OLCF will host a virtual office hour on Thursday, May 16 from 1:00-2:00pm EDT for OLCF users participating in the NERSC-hosted OpenMP training series.  This will be for Session 1, OpenMP introduction. This hour gives you the opportunity to talk with experts at OLCF about questions you may have about the homework and how to do that work on Frontier or other OLCF systems. We will take “walk-ins”, but please register so we can prepare for you.

OpenMP Training Series: Tasking
June 10, 12 – 1:30 p.m.

The OpenMP training series is part of the Performance Portability Training Series and OpenMP Training Series.  Offered by NERSC, OCLF, and ALCF, the series features training sessions on various performance portable programming solutions to help ease developer transitions between current and emerging high-performance computing (HPC) systems, such as the NERSC Perlmutter and Polaris (AMD CPU and Nvidia GPU), OLCF Frontier (AMD CPU and GPU), and ALCF Aurora (Intel CPU and GPU).

Julia for HPC & Intro to Julia for Science
June 18-21, 1 – 4:00 p.m.

The Oak Ridge Leadership Computing Facility (OLCF) in conjunction with ORNL Neutron Sciences and NERSC, will host a (virtual) Julia training for scientists consisting of two events:

  • June 18 Julia for HPC 1:00-4:00 pm EDT
  • June 21 Introduction to Julia for science 1:00-4:00 pm EDT

Julia proposes to fill a gap in the high-performance plus high-productivity space being a dynamic language built on top of LLVM with lightweight interoperability with C and Fortran code, and a unified ecosystem for data science and reproducibility.

New User training announcement
June 27th, 1:00 PM – 3:30 PM (EST)
Virtual via Zoom

OLCF will offer hands-on New User training targeted mostly at users and students who are early in their journey with using an HPC user facility. However, more advanced new users will get the benefit of the latest updates on our hardware and software and may enjoy some of the creative hands-on exercises that we have planned. We will familiarize users with our center and timely updates about hardware software and policies, give best practices, and get users started compiling and running a simple code on Frontier. Hands-on exercises are part of each section that we cover, so users will not go more than 20 minutes without doing a hands-on exercise during the training.
