PEPC : Pretty Efficient Parallel Coulomb-solver

  title={PEPC : Pretty Efficient Parallel Coulomb-solver},
  author={Paul Gibbon},
An parallel tree code for rapid computation of long-range Co ulomb forces based on the Warren-Salmon ‘Hashed Oct Tree’ algorithm is described. Communication ov erhead is minimised by bundling multipole data for large groups of particles prior to shipment. Implem entations on the Cray T3E and the IBM-p690 cluster show the expected O(N log N) scaling with… CONTINUE READING
