Voltaire says its 40 Gbs InfiniBand switches can speed up High Performance Computing (HPC) applications, stuff whose business value is in their speed such as reservoir modeling, fluid dynamics and crash analysis, by as much as 10x.
All it takes is a painless software upgrade to the switch; no changes to the applications software. If the applications are MPI-based, the scheme works out-of-the-box.
See, Voltaire has figured out a way to kill off a lot of the needless chatter that goes on in scale-out data center fabrics - there’s a lot of redundant messages that it can short circuit and accelerate group communications or MPI collective operations by removing bottlenecks at both the node and interconnect levels and generating only a single message over each physical wire.
