Parallel Processing in Eigenfunction-based Spatial Filtering Using MPI+OpenMP Hybrid Parallelization

    Abstract
  • Based on the master/slave model,we present a hybrid MPI+OpenMP parallel implementation for the eigenfunction-base spatial filtering on the multi-core cluster.There are two different implementations of the algorithm: one based on MPI and the other based on a hybrid parallel paradigm with MPI+OpenMP.The experimental results show that MPI+OpenMP method can cut down the process-time effectively and improve the filtering efficiency.
