General Lab Information


The Computational Science Initiative at Brookhaven National Laboratory (BNL) is organizing in conjunction with Argonne National Laboratory (ANL), Oak Ridge National Laboratory (ORNL) and Lawrence Livermore National Laboratory (LLNL), the OpenMP Virtual Hackathon, on April 8 and April 11-13, 2022. This event is sponsored by the Exascale Computing Project (ECP), and driven by the ECP SOLLVE Project. We encourage participation of teams specially interested in porting and optimizing their applications by using the latest OpenMP features.

Hackathon Goal

The goal of this hackathon is to port, optimize and evolve applications towards the latest OpenMP versions. This event will be co-organized with ANL, ORNL, and LLNL. In practical terms, this event will enable application teams and developers to accelerate their code with the use of GPUs, as well as exploiting the latest OpenMP functionality targeting different platforms. Prospective user groups of large hybrid CPU-GPU systems will send teams of at least 3 developers along with either (1) a scalable application that could benefit from GPU accelerators, or (2) an application running on accelerators that has already written OpenMP and needs optimization or (3) applications that have OpenACC (and/or using other programming models) in their codes and need assistance to convert them to OpenMP offload.

There will be intensive mentoring during this 4-day hands-on event. At the conclusion of the event, participating teams will have a functional GPU-accelerated code, or at least, a clear roadmap of how to get there. To support the hackathon goal, we will have a number of mentors from DOE Labs, universities, and other vendors on-site during the event. Our mentors have extensive experience in programming GPUs, actively participate in the OpenMP language committee, and conduct research and development in compilers and tools with OpenMP support.

Target Audience and Format

We are looking for teams, each consisting of 3-5 developers, that wish to work on the optimization and porting of an application to GPU accelerators. Small-to-medium sized applications, mini-apps or specific test cases are especially encouraged. Hence, participating teams should devote significant efforts to isolate the compute/data intensive parts of the code to be optimized. In particular, the development of suitable test-harness and verification machinery to validate that no errors are being introduced during this work-intensive event. Collectively the team should know the application intimately. If an application is a suite of apps, no more than two per team is allowed and a minimum of 2 people per app must attend.

How to Apply

Please note that event is by invitation only, and invited teams will need to submit a Team Hacking Application Form in order to be considered for participation. You will have to provide a team name, a brief summary of the application, your intended goals, software/package dependencies, and the list of team members (full name, affiliation, and, organizational, email). In addition, select in the application form whether the application is sensitive in any way (e.g., only for DOE use, not accessible to foreign nationals, is it NDA protected, etc.). If in doubt, please contact us.

Participation in the training event is free of charge. The Zoomgov meeting room, Slack workspace, as well as access to systems throughout the event are offered by ECP, ORNL, and our event sponsors. The deadline to submit an application is March 21, 2022.

Team application submission is now closed.
