Ethernet — The high performance alternative to InfiniBand. Need Proof?

January 31, 2013

It’s called iWARP or RDMA over Ethernet – see the benchmark tests that show comparable real world performance of 10Gbps Ethernet with the latest FDR InfiniBand. Using the well-known applications LAMMPS, LS-DYNA, HPL, and WRF, the paper shows how mature, robust, and competitive iWARP is and how it enables MPI applications to run unmodified on familiar and preferred Ethernet technology.

iWARP, the standard for RDMA over Ethernet, standardized by the Internet Engineering Task Force (IETF) and supported by industry leading 10 Gbps Ethernet vendors, is a low latency, high bandwidth solution for supporting high-performance computing on top of TCP/IP. Since iWARP runs on top of proven TCP/IP, it functions perfectly with existing standard Ethernet switches and routers.
