Reducing Network Contention With Mixed Workloads on Modern Multicore Clusters
Source: Ohio State University
Multi-core systems are now extremely common in modern clusters. In the past commodity systems may have had up to two or four CPUs per compute node. In modern clusters, these systems still have the same number of CPUs, however, these CPUs have moved from single-core to quad-core and further advances are imminent. To obtain the best performance, compute nodes in a cluster are connected with high-performance interconnects. On nearly all clusters, the number of network interfaces is the same on current multi-core systems as in the past when there were fewer cores per node.
