A high performance communications and memory caching scheme for molecular dynamics on the CM-5

Presents several techniques that we have used to optimize the performance of a message-passing C code for molecular dynamics on the CM-5. We describe our use of the CM-5 vector units and a parallel memory caching scheme that we have developed to speed up the code by more than 50%. A modification that decreases communication time by 35% is also presented, along with a discussion of how we have been able to take advantage of the CM-5 hardware...
