Many recent supercomputers employ either a cluster-based design or a highly scalable network.
Clustering is built-in in a hierarchical system, while highly scalable networks like mesh or torus could be easily partitioned into modules to form several clusters. Usefulness of WICI routing has been demonstrated for the hierarchical network of dBCube and large networks like mesh and torus, and simulation results for WICI routing are compared with wormhole and virtual cut-through routings.
