Title
Benchmarking parallel application performance across SCD infrastructure
Contributors
C Iddon (STFC Rutherford Appleton Laboratory)
Abstract
Two benchmarks (HPL and IMB) are run across SCARF, LOTUS and the SCD Cloud to measure the effect of bandwidth, latency, distributing cores between nodes and using newer hardware on parallel application performance. A common ranking between different methods of communication is shown in the results of all benchmarks (SHM-1, SHM-2, IBV then TCP). Whilst using newer processors is found to have the greatest impact on parallel application performance, both SCARF and LOTUS are shown to be able to perform as effectively between cores on separate hosts as on an individual host - despite lower bandwidth and higher latency. The Cloud performs similarly to the oldest SCARF host (scarf10) but with a higher TCP bandwidth.
