  The HPC community shows a keen interest in creating diversity in the CPU
ecosystem. The advent of Arm-based processors provides an alternative to the
existing HPC ecosystem, which is primarily dominated by x86 processors. In this
paper, we port an Asynchronous Many-Task runtime system based on the ParalleX
model, i.e., High Performance ParalleX (HPX), and evaluate it on the Arm
ecosystem with a suite of benchmarks. We wrote these benchmarks with an
emphasis on vectorization and distributed scaling. We present the performance
results on a variety of Arm processors and compare it with their x86 brethren
from Intel. We show that the results obtained are equally good or better than
their x86 brethren. Finally, we also discuss a few drawbacks of the present Arm
ecosystem.
