A Performance Analysis Of The First Generation Of HPC‐Optimized Arm Processors


In this paper, the authors present performance results from Isambard, the first production supercomputer to be based on Arm CPUs that have been optimized specifically for HPC. Isambard is the first Cray XC50 “Scout” system, combining Cavium ThunderX2 Arm‐based CPUs with Cray's Aries interconnect. The full Isambard system contained over 10,000 Arm cores. In this work, we present node‐lev... » read more
