| The research of electromagnetic scattering from complex target has atracts much attentions for a long time for strong engineering application requirement .The parallel multilevel fast multipole method based on MPI in cluster have been studied in this paper.Firstly , The background of cluster is introducted and compared several cluster system , such as NOW , Beowulf, OSCAR , SCE and Rocks.Following , The integral equation method and multilevel fast multipole method are reviewed .Finally , The parallel multilevel fast multipole method is studied in detail with the dummy tree , the broad tree , the mlfma forest, morton key and poll-token communication modal.A cube who's length of each side is 30A have been calculated in 2-node cluster , the number of unknown reach to 400 , 000. |
