The development of the A64FX processor by Fujitsu has allowed the re-emergence of vectorized processors and the birth of the first supercomputer to achieve top speeds in all 5 of the major HPC benchmarks. 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 A64FX processor onA64FX clusters at Stony Brook University and RIKEN in Japan.
