Regular readers will no doubt remember Ethernet switch maker Woven Systems from previous coverage in this space. The company makes adaptively routed 10 Gbps Ethernet switches that can be ganged together to connect up to 4,000 servers while staying in layer 2 (and thus avoiding all that nasty overhead).
They’ve got news this week; Woven…
…announced that the prestigious Max Planck Institute for Gravitational Physics (Albert Einstein Institute, Hannover, Germany) is using Woven’s EFX 1000 10 Gigabit Ethernet (10 GE) Fabric Switch and TRX 100 Ethernet Switch in a large HPC cluster to search for gravitational waves predicted by Albert Einstein’s General Theory of Relativity.
…During the Institute’s extensive acceptance testing, the Woven Ethernet Fabric achieved over 30 Teraflops of performance using the HPC Linpack benchmark, which places the application on par with the Top 50 of the www.Top500.org list from November 2007. Based on Woven’s vSCALE Dynamic Congestion Avoidance capability in a non-blocking 10 Gigabit Ethernet Fabric, the cluster was able to reach 64 percent of the theoretical peak efficiency possible. “The HPC Linpack experts we consulted tell us that they have never seen such high Gigabit Ethernet efficiencies on such a large cluster,” Professor Allen adds.
