With the growing move of parallel processing towards networks of workstations (NOWs), caused by a low cost to performance ratio, process migration has once again become an important area of research. This paper reports on research into the design, implementation and performance of RHODOS's process migration facility which reflects RHODOS's aspiration to support both parallel execution and load balancing on a distributed system. This design is original in that it applies strictly to the microkernel and client/server paradigms. Furthermore, following RHODOS's adherence to the object based approach, the RHODOS process Migration Manager only coordinates process migration. The actual transfer of the process's resources: process state, address space and communication state, are performed by the Process, Space and IPC Managers, respectively. Following the presentation of the design issues, research into the implementation and testing of RHODOS's process migration facility is presented. Performance measurements of this implementation have also been taken to determine the cost of using the supposedly slower microkernel based approach and the results are reported in this paper. A summary of process migration for modern distributed operation systems is presented. © 1998 Elsevier Science Inc.
