Improving HPC Cluster Performance Through Communication Efficiency
Overview Typically, a High-Performance Computing (HPC) cluster loosely couples multiple Symmetric Multiprocessing (SMP) platforms into a single processing complex. Each SMP server uses shared memory for its processors to communicate, whereas communication across the SMP servers travels through the intra-cluster interconnect. Analyzing the communication pattern of processes helps to map the processes to processors, thus ensuring optimal communication paths for critical traffic. This paper explains how changing process-to-processor mapping on a cluster can improve overall system performance, particularly if the interconnect between machines is based on a slower networking technology such as Fast Ethernet.
