Heterogeneous Process Migration by Recompilation

摘要

Heterogeneous process migration involves moving a process between machines thathave differing hardware and software configurations, including different processor architectures, machine instruction sets, and operating systems. The paper describes an approach to heterogeneous process migration that involves building a machine-independent 'migration program' that specifies the current code and data state of the process to be migrated. When the program is compiled and executed on the target machine, it will first reconstruct the process's state and then continue the normal execution of the now-migrated process. The principal advantage of this approach is that it hides the details of code and data translation in the compilers for each machine. (Copyright (c) 1992 Xerox Corporation.)
