RUSSIAN 3D-TORUS INTERCONNECT WITH GLOBALLY ADDRESSABLE MEMORY SUPPORT

Abstract

This paper gives the overview and early results of prototyping of the 3d-torus interconnect developed in NICEVT, Moscow. This interconnect was designed to be equally effective in small-size computing clusters and petascale systems. The key features of the interconnect are high fault-tolerance, high message rate per core supported by host adapter and hardware support for globally addressable memory provided via SHMEM parallel programming library.
