Large Scale ARM Computing Cluster and its Application in HEP
September 28, 2022
With the advancement of several large scientific experiments in the field of high-energy physics, the speed of data generation continues to increase and will reach exabyte(EB) levels in the next decade. This puts forward higher requests for data storage and computation processing. Reducing reliance on a single chip architecture can provide more cost-effective storage and computing solutions. We built a supercomputer cluster with 9,600 computing cores based on the ARM architecture in Dongguan, China. On this ARM cluster, we ported some common software for high-energy physics and made some optimizations for Lattice quantum chromodynamics(LQCD). In addition, we compared the performance of ARM and X86 in many application scenarios, which is beneficial to improve computational efficiency.
How to cite
Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
