摘      要：Usually simulations on environment flood issues will face the scalability problem of large scale parallel *** plain parallel technique based on pure MPI is difficult to have a good scalability due to the large number of domain ***,the hybrid programming using MPI and OpenMP is introduced to deal with the issue of *** kind of parallel technique can give a full play to the strengths of MPI and *** the parallel computing,OpenMP is employed by its efficient fine grain parallel computing and MPI is used to perform the coarse grain parallel domain partitioning for data *** the tests,the hybrid MPI/OpenMP parallel programming was used to renovate the finite element solvers in the BIEF library of *** was found that the hybrid programming is able to provide helps for Telemac to deal with the scalability issue.
