50 GFlops molecular dynamics on the Connection Machine 5
Peter S. Lomdahl, Pablo Tamayo, Niels Grønbech‐Jensen, David M. Beazley · 1993
We present timings and performance numbers for a new short range three dimensional (3D) molecular dynamics (MD) code, SPaSM, on the Connection Machine-5 (CM-5).We demonstrate that rurM with more than 108 particles are now possible on massively parallel MIMD computers.To the best of our knowledge this ti at least an opder of magnitade more particles than what has previously been reported.Typical production runs show sustained performance (including communication) in the range of 47-50 GFlops on a 1024 node CM-5 with vector units (VUS).The speed of the code scales linearly with the number of processors and with the number of particles and shows 95% parallel eficiency in the speedup.Passing Multi-Cell Molecular Dynamics on the Connection Machine 5, Parall.Comp.
