Summary

Researchers from Advanced Micro Devices Inc. detail performance optimizations made in rocHPL, an open-source implementation of the High-Performance Linpack benchmark, targeting accelerated node architectures designed for exascale systems like the Frontier supercomputer. Optimizations include a multi-threaded approach to computing panel factorization, time-sharing of CPU cores, and hiding MPI communication, achieving over 1 ExaFLOPS on a single node of the Frontier early access cluster and scaling to multiple nodes.
