The bandwidth seems not a problem but how about the latency or delay? Your packet-size is pretty larger than mine and a network interface (assuming one for a node comupter) sends packets in seccession with TCP. UDP reduces maximum delay time to 1/(number of nodes to send). >> How's about the network devices? The cluster uses InfiniBand or similar >> high speed interface devices? > >Standard Ethernet. That is, usual 1 Giga bit Ethernet? Sorry for asking again, because HPC clusters' standard is 10 Giga bit or more. >> What's the processor? Intel Xeon or IBM Power? > >x86 architecture, 64 bits.
