Intel Ethernet Server Cluster Adapters support iWARP, or RDMA over Ethernet which enables high-performance, low-latency networking.  But to take advantage of this, applications must be written to use an RDMA API.  Many HPC applications are already enabled for RDMA, but most datacenter applications are not.   A “hello world” programming example on the Intel site provides good guidance on how this can be accomplished, but the OpenFabrics Alliance is now providing a unique opportunity to learn how to code to an RDMA interface by hosting an RDMA programming training class.  This is definitely worth looking into if you are an application writer familiar with a Sockets interface and interested in how to take advantage of iWARP.
