Open publisher page 0 citations

Abstract

In a massively parallel processors(MPP) system, router constitutes primary factor influencing performance of interconnect network and MPP system. Through careful analysis of message routing on interconnection network, concept of the best network for routing(BNR) is proposed. By using it a new BNR-based minimal deadlock-free fully-adaptive algorithm on mesh (BBFAM) is designed. With new proposed dynamic-priority control technology and freedom-degree based channel selection policy, a high performance router: BFR (the BNR-based fully adaptive router) is obtained.
