Limulus 100-400
10 Gigabit Ethernet Upgrade

Limulus 100-400<br /> 10 Gigabit Ethernet Upgrade
$1,295.00 each

Add lower latency and more bandwidth to any Limulus system!

The HPL benchmark run on a Limulus Model 100 went from 385.5 GFLOPS (52% of peak using 1 GbE) to 567.4 GFLOP (76% of peak using 10 GbE). Not all codes will see this type of increase, however latency sensitive codes show much better performance overall.

The option adds full 10 GbE capability between all nodes using a switch-less design. The single byte TCP latency (as measured by Netpipe) ranges from 8-11 ┬Áseconds (in some cases a packet may need to hop across a network card adding 3-4 ┬Áseconds). The maximum TCP bandwidth is 9.300 Gb/sec (10.0 Gb/sec is peak for 10 GbE) with a N/2 of 120,000 Bytes. All systems come full configured and ready to run.

This upgrade must be purchased with a Limulus system and is available on all models 100,200,300,and 400. It is not intended as a user installable option.
