Abstract

The authors propose a new approach for subcube and noncubic processor allocations forhypercube multiprocessors. The main idea is to represent available processors in thesystem by means of a prime cube graph (PC-graph). The PC-graph maintains theinter-relationships between free subcubes and hence reduces both internal and externalprocessor fragmentations. Their simulation results show that the PC-graph approachoutperforms the existing allocation strategies by 25% to 50% under certain loadconditions.
