Popis: Network-on-chip (NoC) multi-core architectures with a large number of processing elements are becoming a reality with the recent developments in technology. In these modern systems the processing elements are interconnected with regular NoC topologies such as meshes and tori. In this paper we propose a parallel Gauss-Seidel (GS) iterative algorithm for solving large systems of linear equations on a 3-dimensional torus NoC architecture. The proposed parallel algorithm is O( Nn 2 / k 3 ) time complexity for solving a system with a matrix of order n on a k × k × k 3D torus NoC architecture with N iterations assuming n and N are large compared to k . We show that under these conditions the proposed parallel GS algorithm has near optimal speedup.
