| dc.description.abstract | The new 2018 nodes in the cluster taki in the UMBC High Performance Computing Facility contain two 18-core Intel Skylake CPUs and 384 GB of memory per node, connected by an EDR (Enhanced Data Rate) InfiniBand interconnect. Parallel performance studies for the memory-bound test problem of the Poisson equation in three spatial dimensions yield several conclusions for the operation of the CPU cluster in taki. Strong scalability studies demonstrate excellent performance when using multiple nodes due to the low latency of the high-performance interconnect and good speedup when using all cores of the multi-core CPUs. Weak scalability studies confirm that best throughput is achieved by using all cores on a shared-memory node. Both types of performance studies highlight that parallel code is needed to take full advantage of the large number of computational cores on the high-memory 2018 nodes. | en |
