General Lab Information

Call for Team Applications - All current and potential GPU users from national labs, universities, industry and other institutions are welcome to submit a team application to attend the GPU Hackathon. The deadline to submit an application is May 31, 2022 - 11 PM PT / 2 AM ET. Notification of acceptance will be sent out by June 23, 2022.


Together with NVIDIA, and Oak Ridge National Laboratory (ORNL), Brookhaven National Laboratory (BNL) will host a virtual GPU Hackathon starting August 15 and concluding August 24, 2022. GPU Hackathons provide exciting opportunities for scientists to accelerate their AI research or HPC codes under the guidance of expert mentors from National Labs, Universities and Industry leaders in a collaborative environment. This Hackathon is a multi-day event designed to help teams of three to six developers accelerate their own codes on GPUs using a programming model, or machine learning framework of their choice. Each team is assigned mentors for the duration of the event.


Currently there are several large-scale computing systems in the US that are based on General-Purpose Graphic Processing Units, or GPGPUs, including Summit at ORNL, Sierra at Lawrence Livermore National Lab and the Perlmutter machine at NERSC. In addition, the upcoming exascale computers, Aurora at Argonne National Laboratory (ANL), and Frontier at ORNL, will have GPU accelerators as well. These GPU-based supercomputers offer tremendous computing power for science and engineering, but writing efficient software to take full advantage of them may be challenging.


The goal of this 4-day intensive hands-on Hackathon is for current or prospective user groups of large hybrid CPU-GPU systems to send teams of at least 3 developers along with either a potentially scalable application that could benefit from GPU accelerators, or an application running on accelerators that needs optimization. There will be intensive mentoring during the hackathon, with the goal that the teams leave with applications running on GPUs, or at least with a clear roadmap of how to get there. Our mentors come from national laboratories, universities and vendors, and besides having extensive experience in programming GPUs, many of them develop the GPU-capable compilers and help define standards such as OpenACC and OpenMP.

Prerequisites and Team Application Submission

  • Teams are expected to be fluent with the code or project they bring to the event and motivated to make progress during the hackathon.
  • At least 3 team members must be participating throughout the entire event.
  • Projects brought to the event are required to have a license attached and detailed in the application. For more information on why licenses are important and how to obtain one, please use the following links:
  • No advanced GPU skills are required, but teams are expected to know the basics of GPU programming and profiling. A collection of GPU lectures, tutorials, and labs are available for all participants at no fee. Please contact organizers for more information to help you prepare for the hackathon.

GPU Compute Resources:

Teams attending the event will be given access to a GPU cluster for the duration of the Hackathon.

Event Format:

The BNL GPU Hackathon will be hosted online with all times Eastern Time (ET). All communications and collaborations will be conducted via Zoom, Slack and email.

Once your team application has been submitted, reviewed and accepted, all participating team members as well as Hackathon mentors must submit an additional Brookhaven Lab Guest Registration Form by July 15, 2022.
