SRT interconnection network on 3D stacked implementation by considering thermo-radiation

Abstract

This paper addresses the reconfiguration of Shifted Recursive Torus (SRT) network by considering thermo-radiation in stacked wafers implementation. The SRT networks are hierarchical torus networks and suitable for massively parallel systems. We propose fault-tolerance schemes for SRT networks to keep high network performance in stacked wafers implementation. The cooling of stacked wafers, however, is one of the most crucial problems for implementation of massively parallel systems. Two cooling approaches have been proposed for SRT in stacked implementation. Introducing a thermo-radiation model into SRT in stacked implementation, reconfiguration performance of SRT was evaluated. Comparing the system yields and the maximum temperatures, these cooling approaches can keep high system yield and lower temperature of 3D implementation.
