Performance Modeling of Fault Tolerant Fully Adaptive Wormhole Switching 2-D Meshes in Presence of Virtual Channels

In recent decades, researchers try to construct high performance interconnection networks with emphasis on fault tolerance. Their studies are based on this fact that, a network can be a major performance bottleneck in parallel processors. This paper proposes an analytical model to predict message latency in wormhole-switched mesh as an instance of a fault tolerant routing. The mesh topology has desirable properties such as modularity, regularity in structure, partitioning to smaller one, simplicity in implementation. To achieve our purpose we modeled an algorithm suggested by Linder-Harden, then performance of this model was evaluated by using XMulator.
