Desktop Supercomputer - Performance
During the build process the four nodes were connected together with gigabit Ethernet rather than the 100Mbit used now. After a lot of playing around with HPL (Linpack) the highest performance benchmark value achieved was 116 Gigaflops. I haven't re-run the test since the reduction to 100Mbit networking. I guess it would be slower - but as the main application on Seymour doesn't saturate the network in any way, I'm satisfied that I'm still extracting the maximum available processing power from all 16 CPU's.
116 Gigaflops is roughly as powerful as a mid 1990's supercomputer.
This beats my favourite computer of all time, the 250 Megaflops Cray 1, but it is still totally blasted away by the current worlds fastest computer, the BlueGene/L which runs at a terrifying 596 Teraflops.
