Abstract
A major difficulty of heterogeneous process migration is how to collect advanced dynamic data-structures, trans- form them into machine independent form, and restor them appropriately in a different hardware and software environ- ment. In this study we introduce a data model, the Mem- ory Space Representation (MSR) model, to recognize com- plex data structures in program address spaces. Support- ing mechanisms of the MSR model are also developed for collecting program data structures and restoring them in a heterogeneous environment. The MSR design has been im- plemented under a prototype heterogeneous process migra- tion environment. Pointer-intensive programs with function and recursion calls are tested. Experimental results confirm that the newly proposed design is feasible and effective for heterogeneous network process migration.
