Lessons for massively parallel applications on message passing computers

A decade\´s work on message passing MIMD (multiple instruction-multiple data) parallel computers in the areas of hardware, software, and applications is reviewed. The author concludes that distributed memory parallel computing works, and he describes the implications of this for future portable software systems. He claims that the message passing model was and will continue to be very successful. The vendors will build better hardware with lower communication latency and reasonable t/sub comm//t/sub calc/>
