The development of the A64FX processor by Fujitsu has created a massive\ninnovation in High-Performance Computing and the birth of Fugaku: the current\nworld's fastest supercomputer. A variety of tools are used to analyze the\nrun-times and performances of several applications, and in particular, how\nthese applications scale on the A64FX processor. We examine the performance and\nbehavior of applications through OpenMP scaling and how their performance\ndiffers across different compilers on the new Ookami cluster at Stony Brook\nUniversity as well as the Fugaku supercomputer at RIKEN in Japan.\n
