Impact of the implementation of MPI point-to-point communications on the performance of two general sparse solvers von Amestoy, Patrick R, Duff, Iain S, L’Excellent, Jean-Yves, Li, Xiaoye S

“… : a multifrontal solver ( MUMPS), and a supernodal one ( SuperLU). The performance of our initial strategies based on simple MPI point-to-point communication primitives is very sensitive to the MPI system, particularly the way MPI buffers are used …”
