Abstract
A process migration method comprising executing a computer program using a group of parallel processes, each process carrying out a computation, the execution using current computing resources to provide current group data as a result of the computations, deciding to change the resources, and making a choice between increasing the resources; decreasing the resources; and moving to different resources, wherein moving to different resources can include increase, decrease or maintenance of the resources. The method comprising communication between the current computing resources and changed computing resources to allow the program to execute on the changed resources, the communication comprising migration of the execution to changed resources and synchronization of migrated group data with the current group data; wherein execution using the current resources overlaps in time with the communication.
