Dual Processor Nodes for HPC Clusters: Network Connections
Douglas Eadline, Ph.D.
Tests were run to determine the effect of sharing an Ethernet interface
on a dual SMP node. The tests, as expected, indicate interface contention
on the shared interface. Both Netperf and Netpipe tests were run on
three different motherboard/chipset systems. The use of two Ethernet
interfaces with the NAS test suite was explored. The results indicate
dual SMP systems can benefit from multiple interfaces.
