  The development of the A64FX processor by Fujitsu has created a massive
innovation in High-Performance Computing and the birth of Fugaku: the current
world's fastest supercomputer. A variety of tools are used to analyze the
run-times and performances of several applications, and in particular, how
these applications scale on the A64FX processor. We examine the performance and
behavior of applications through OpenMP scaling and how their performance
differs across different compilers on the new Ookami cluster at Stony Brook
University as well as the Fugaku supercomputer at RIKEN in Japan.
