Evaluating the Arm Ecosystem for High Performance Computing
In recent years, Arm-based processors have arrived on the HPC scene, offering
an alternative the existing status quo, which was largely dominated by x86
processors. In this paper, we evaluate the Arm ecosystem, both the hardware
offering and the software stack that is available to users, by benchmarking a
production HPC platform that uses Marvell's ThunderX2 processors. We
investigate the performance of complex scientific applications across multiple
nodes, and we also assess the maturity of the software stack and the ease of
use from a users' perspective. This papers finds that the performance across
our benchmarking applications is generally as good as, or better, than that of
well-established platforms, and we can conclude from our experience that there
are no major hurdles that might hinder wider adoption of this ecosystem within
the HPC community.Comment: 18 pages, accepted at PASC19, 1 figur
