Exascale Computing Project: RAJA Portability Suite Enables Performance Portable CPU and GPU HPC Codes

A growing number of HPC applications must deliver high performance on CPU and GPU hardware platforms.  One software tool available now and showing tremendous promise for the exascale era is the open-source RAJA Portability Suite. RAJA is part of the Exascale Computing Project (ECP) NNSA software portfolio and is also supported by the ECP Programming Models and Runtimes area.

Video: Preparing to program Aurora at Exascale – Early experiences and future directions

Hal Finkel from Argonne gave this talk at IWOCL / SYCLcon 2020. “Argonne National Laboratory’s Leadership Computing Facility will be home to Aurora, our first exascale supercomputer. This presentation will summarize the experiences of our team as we prepare for Aurora, exploring how to port applications to Aurora’s architecture and programming models, and distilling the challenges and best practices we’ve developed to date.”
