The software interface for a cluster interconnect based on the Kautz digraph

The Kautz digraph (Elspas et al., 1968) has been described as the ideal communication network for parallel computers, but it is generally unknown in the engineering community, and has never previously been used in a commercial product. We will define and characterize it in relation to HPC clusters,...

Summary:The Kautz digraph (Elspas et al., 1968) has been described as the ideal communication network for parallel computers, but it is generally unknown in the engineering community, and has never previously been used in a commercial product. We will define and characterize it in relation to HPC clusters, then discuss some of the implementation issues encountered in developing it as a large-scale cluster interconnect. The software interface to this interconnect is explained with some initial experiences with performance benchmarks.
