摘要：

We present a new scalable algorithm for short-range molecular dynamics simulations on distributed memory MIMD multicomputers based on a message-passing multi-cell approach. We have implemented the algorithm on the Connection Machine 5 (CM-5) and demonstrate that meso-scale molecular dynamics with more than 10(8) particles is now possible on massively parallel MIMD computers. Typical runs show single particle update-times of 0.15 mus in 2 dimensions (2D) and approximately 1 mus in 3 dimensions (3D) on a 1024 node CM-5 without vector units, corresponding to more than 1.8 Gflops overall performance. We also present a scaling equation which agrees well with actually observed timings.
