Abstract :
One-to-all broadcast (OAB) and all-to-all broadcast (AAB) (Defago, 2003) group communications are frequently used in many parallel algorithms and if their overhead is excessive, performance degrades rapidly with processor count. This paper deals with the design of a new application specific Bayesian optimization algorithm (BOA) and standard genetic algorithm (SGA) that both produce almost optimal communication schedules for an arbitrary multiprocessor topology. We demonstrated the optimization process on hypercube and AMP topology (Chalmers, 1996) using wormhole (WH) switching
