Moving paragon™ operating system to a new hardware platform

This paper discusses some of the problems, solutions, and strategies discovered while moving features of Paragon1 Operating System (OS) to a new hardware platform. The new hardware platform differs from the Paragon System in several areas, including processor architecture, multiprocessor capabilities, I/O support, and interconnect technology. Performance metrics for critical-path message-passing software and other OS microfunctions are compared to the existing Paragon platform.
