The quality indicators of network transmission service such as traffic throughput, latency, fault-tolerant rate are directly affected by NoC routing algorithm. This paper presents wormhole routing optimization algorithm based on the virtual channel switching. The optimization algorithm is based on the combinations of the virtual channel transmission mechanism and routing algorithm. The virtual channels...
A Hierarchical Torus Network (HTN) is a 2D-torus network of multiple basic modules, in which the basic modules are 3D-torus networks that are hierarchically interconnected for higher level networks. The dynamic communication performance of the HTN using the dimension-order routing under common traffic patterns have been evaluated, and have been shown to be good. However, dynamic communication performance...
The static network performance and dynamic communication performance of the Hierarchical Torus Network (HTN) using dimension-order routing algorithm have already been evaluated and shown to be superior to the performance of other interconnection networks. However, the assessment of the dynamic communication performance improvement of HTN by the efficient use of both the physical link and virtual channels...
A Modified Hierarchical 3D-Torus (MH3DT) network is a 3D-torus network of multiple basic modules, in which the basic modules are themselves 3D-torus networks which are hierarchically interconnected into higher-level networks. The static network performance of the MH3DT has already been studied and has been shown to be good. Dynamic communication performance has been evaluated using dimension-order...
In this paper, we present a deadlock-free routing algorithm for the Tori connected mESH (TESH) network using 2 virtual channels - 2 being the minimum number for dimension-order routing - and evaluate the networks dynamic communication performance under the hot-spot traffic pattern, using the proposed routing algorithm. We evaluate the dynamic communication performance of TESH, mesh, and torus networks...
Interconnection networks play a crucial role in the performance of massively parallel computers. Hierarchical interconnection networks provide high performance at low cost by exploring the locality that exists in the communication patterns of massively parallel computer systems. The Tori-connected mESH (TESH) Network is a 2D-torus network of multiple basic modules, in which the basic modules are 2D-mesh...
