The NNSA-University Workshop on Exascale Simulation Technologies (NUWEST) will be held on Thursday January 18, 2024 in Albuquerque at the Crowne Plaza. The overarching goal of NUWEST is to share ideas on technologies for facilitating exascale predictive science, by showcasing available technologies, identifying challenges, and initiating further collaborations with NNSA laboratory efforts.
The workshop will highlight technologies from PSAAPIII centers. The schedule is below.
The workshop is designed to encourage hands-on demonstration of technologies used in and employed across the centers in their predictive simulations, with a goal of encouraging wider adoption of the key concepts in the technology itself or direct use of the underlying software.
Lunch is provided, along with a breakfast and coffee throughout the day. If you
have questions, then please contact Luke Olson (lukeo at illinois.edu) or
Courtney McLearin (cmcleari at illinois.edu).

| Success through Community Building – A Kokkos Story Christian Trott, Sandia National Laboratories Abstract: What makes a successful Open Source project – and what does it take to achieve wide spread adoption? This talk will explore these questions based on the experience with Kokkos. Now with users at more than 150 institutions, Kokkos represents one of the success stories of DOE’s recently concluded Exascale Computing Project. But technical excellence alone wasn’t enough – a critical aspect of Kokkos adoption progress was the proactive effort of the Kokkos team to widen the contributor base, build a user community, and develop trust. The talk will give an overview of the community efforts Kokkos has undertaken and how trust was build, as well as provide a view into the future of Kokkos as part of the High Performance Software Foundation. |

| Getting to adoption: Lessons from MPI and PETSc Bill Gropp, University of Illinois Urbana-Champaign Abstract: Many software projects measure their success by the number of users that adopt that software for their work. Few succeed in getting significant adoption. What do these two successful projects tell us about getting an HPC tool to adoption by the community? This talk will review the history of two different projects: PETSc, a software library designed to support the development of applications to solve PDEs in parallel, and MPI, a specification (not a library) for communicating between processes. The importance of both the design and implementation of the projects as well as the marketing and support are discusses, and lessons for other HPC projects are discussed. |
