The Design and Implementation of a Microkernel-Based Parallel OS 'Cenju-3/DE'

摘要

Cenju-3/DE is a microkernel-based parallel OS developed for research and development on the distributed memory parallel machine Cenju-3. Its features are to provide various high-performance Interprocessor Communication (IPC) facilities and to adopt open and standard components such as the Mach microkernel, UNIX and MPI (Message Passing Interface). Cenju-3/DE has archived 185 μsec in latency and 22 Mbps in bandwidth in a multiple task environment (NORMA-IPC/DE); 60 μsec in latency and 19 Mbps in bandwidth in a single task environment (MPI/DE); and 25 μsec in latency for user-level IPC (NODO).
