Achieving high performance parallel statistical computing in tightly coupled network of Unix workstations

摘要

We set up the DiPSCS (Distributed Parallel Statistical Computing System) - a multi-CPU system through a tightly coupled network of Unix workstation as a working frame to speed up statistical computing. TCP socket served as the inter-CPU data communication and Unix IPC served as an interface for high speed C program to communicate with slow statistical functions calls in Splus~(TM). By paralleling the CPU intensive module and balanced distribution of system resource, the system can achieve high performance computing without extra cost of multi-processor computer and parallel operating system and compiler. The performance of the DiPSCS is illustrated through solving a computational statistics problem.
