Abstract :
The process migration facility in the Eindhoven multiprocessor system (EMPS) is presented. In the EMPS system, mailboxes are used for interprocess communication. These mailboxes provide transparency of location for communicating processes. The major advantages of mailbox communication in the EMPS system are: (1) interprocess communication can proceed without losing messages; and (2) the communication paths can be updated very efficiently when a process moves to another processor. By redirecting the mailbox connection of the migrating process, the communication paths of all processes connected to the same mailbox are updated
