Comparing the behavior of OpenMP Implementations with various Applications on two different Fujitsu A64FX platforms

Year: 2021

Type: conference-paper

Abstract: The development of the A64FX processor by Fujitsu has been a massive innovation in vectorized processors and led to Fugaku: the current world’s fastest supercomputer. We use a variety of tools to analyze the behavior and performance of several OpenMP applications with different compilers, and how these applications scale on the different A64FX processors on clusters at Stony Brook University and RIKEN.
