Supercomputing Spotlights is a new webinar series featuring short presentations that highlight the impact and successes of high-performance computing (HPC) throughout our world. Presentations, emphasizing achievements and opportunities in HPC, are intended for the broad international community, especially students and newcomers to the field. Supercomputing Spotlights is an outreach initiative of SIAG/Supercomputing (https://siag-sc.org) … Join us!

Abstract: 

The seven-year US Exascale Computing Project (ECP) just finished.  One significant legacy of the project is a curated, coordinated, and performance-portable software ecosystem across three major GPU platforms and CPU-based systems.  In addition, the stack is prepared for rapid adaptation to future highly concurrent devices.

In this talk, we describe the Extreme-scale Scientific Software Stack (E4S), founded on the Spack package management tools, containing more than 100 scientific software libraries and tools, most of which are GPU capable across all major GPU platforms.  We talk about lessons learned from ECP, primarily related to the design of algorithms and software for portable execution on scalable GPU-based systems from AMD, Intel, and NVIDIA.  We focus on a broad set of principles and strategies from the ECP team’s efforts to contribute more than 70 reusable libraries and tools to the open-source scientific and technical computing communities.
