Abstract: The DEEP project implements a novel architecture for high-performance computing consisting of two components - a standard HPC-Cluster and a "Booster" cluster of many-core processors. The Cluster part is built from Intel Xeon multicore processors connected via InfiniBand while the Booster part utilizes Intel Xeon Phi cards and the highly scalable EXTOLL network.This paper describes a forwarding protocol that bridges both interconnects in a highly efficient way. It uses EXTOLL's unique shared memory functional unit to enable transfers of network payload between InfiniBand an EXTOLL. The current implementation delivers nearly 99% of the expected peak performance on an evaluation system.
