A Load Balancing Strategy with Migration Cost for Independent Batch of Tasks (BoT) on Heterogeneous Multiprocessor Interconnection Networks

Inhighperformancecomputing,heterogeneousMultiprocessorInterconnectionNetworks(MINs) areusedforprocessingofcomputeintensiveapplications.Theseapplicationsaredistributedonthe heterogeneouscomputationalprocessorsofMINsarrangedinspecificgeometricalshape.MINsare alsousedfortransfertaskbetweentwoprocessorsinaheterogeneousmultistagenetworkforbetter load balancing. Load balancing algorithm plays a vital role in interconnection network in order tominimizetheloadimbalanceontheprocessors.Inthispaper,aLoadBalancingStrategywith Migrationcost(LBSM)isproposedtoexecuteanindependentbatchoftasksonvariousheterogeneous MINsviz.MetaCube,X-TorusandFoldedCrossedCubehavingtheobjectiveofminimizingtheload imbalanceonprocessors.Insimulationstudy,LBSMiscomparedwithitspreviousworkDLBSand superiorperformanceisshownwiththeconsideredparametersunderstudy.Further,theperformance analysisofLBSMhasbeenconductedonMetaCube,X-TorusandFoldedCrossedCubeandresults havebeenreportedaccordingly.
