We’re Hiring Leaders
The Computing and Computational Sciences Directorate oversees Oak Ridge National Laboratory’s immense store of computing power and its talented staff of computational scientists and mathematicians, conducting state-of-the-art research and development in support of DOE’s missions and programs. The directorate stewards the Oak Ridge Leadership Computing Facility, home to the nation’s most powerful supercomputer, Summit, which enables us to address, with greater complexity and higher fidelity, questions concerning who we are, as well as our place on earth and in our universe. The OLCF will also be home to Frontier, ORNL’s upcoming exascale supercomputer scheduled for delivery in 2021. Join us in building the future. If you are passionate, creative, and collaborative, ORNL offers the opportunity to build an impactful career with like-minded peers. Learn more and apply online.

Meetings & Workshops

Weekly Kokkos Lecture Series (Through Sep 4)
The weekly Kokkos Lecture Series began on July 17 and continues through September 4. The objective of this training os for attendees to learn everything necessary to start using Kokkos to write performance portable code. This 8-part Kokkos Lecture Series consists of 2-hour online lectures every Friday and exercises as homework. The team provides support via GitHub and Slack throughout the time of the training. Events are recorded, so if you have to miss one, you can still watch the video and complete the exercises in time to participate in the next lecture.

TAU Performance Analysis Training
July 28, 2020
1:00 – 3:30 PM (ET)

On Tuesday, July 28, the OLCF will host (virtually) Sameer Shende (University of Oregon) to present a training on TAU performance analysis. TAU Performance System is a portable profiling and tracing toolkit for performance analysis of parallel programs written in Fortran, C, C++, Python. During the training, Sameer will cover TAU using presentations & demos and will also provide example codes for participants to work through. For more information, or to register, please visit:

2020 OLCF GPU Hackathon (virtual)
The OLCF’s annual GPU hackathon is multi-day coding event in which teams of developers prepare their own application(s) to run on GPUs or focus on optimizing their application(s) that currently run on GPUs. Teams typically consist of three or more developers who are intimately familiar with (some part of) their application, and they work alongside two mentors with GPU programming expertise. These hackathons offer a unique opportunity for teams to set aside time for development, surround themselves with experts in the field, and push toward their development goals. During the event, teams will have access to the OLCF’s Ascent training system (same node architecture as Summit). If you’re interested in more information, have questions about the virtual format, or just want to apply, you can visit the event page below. If you have additional questions, please contact Tom Papatheodore.

   – Event Dates: October 19, 26-28 (9 AM – 5 PM (ET))
   – Deadline to apply: August 6, 2020 @ 11:59 PM (ET)

CUDA Training Series
NVIDIA will present a 9-part CUDA training series intended to help new and existing GPU programmers understand the main concepts of the CUDA platform and its programming model. Each part will include a 1-hour presentation and example exercises. The exercises are meant to reinforce the material from the presentation and can be completed during a 1-hour hands-on session following each lecture. The full list of topics can be found on the series page. If you have any questions about this series, please contact Tom Papatheodore.
