es in computer clusters are able to move from machine to machine. Process migration is implemented in, among others, OpenMosix

OpenMosix

openMosix was a free cluster management system that provided single-system image capabilities, e.g. automatic work distribution among nodes. It allowed program processes to migrate to machines in the node's network that would be able to run that process faster...

Process migration alternate definition is coming from IC design and engineering. Process migration or Layout migration is a design flow to change and shrink an existing IC layout to a new process technology node. The implementation of a process migration could be done manually by redrawing the layout feature by feature or by automatic EDA/CAD tools.
