Description
Electrical power requirements will be a constraint on the future
growth of Distributed High Throughput Computing (DHTC) techniques
as used in High Energy Physics. Performance-per-watt is a critical
metric for the evaluation of computer architecture for cost-efficient
computing. Additionally, the future performance growth comes from
heterogeneous, many-core, and high computing density platforms with
specialized processors. In this paper, we examine the Intel Xeon
Phi Many Integrated Cores (MIC) co-processor and Applied Micro's
XGene ARMv8 64-bit low-power server system-on-a-chip (SoC) solutions
for scientific computing applications.
We report our experience on software porting, performance and energy
efficiency and evaluate the potential for use of such technologies
in the context of the distributed computing sytems such as the
Worldwide LHC Computing Grid (WLCG).
