Abstract:
1. A computer-implemented method comprising: detecting an event calling for a migration of a computer workload including an operating system image from a source processor set to a target processor set; in response to said detecting, reconfiguring a fabric so as to pool said source processor set with a second processor set, said source processor set and said second processor set being included in respective distinct computers; first allocating processes of said workload so that some of said processes are executed on said source processor set and, concurrently, some are executed on said second processor set so that said operating system image is across said source processor and said second processor sets; and then second allocating processes of said workload so that no process of said workload is executing on said source processor set and at least some of said processes are executing on said second processor set, said second processor set being said target processor set or being an intermediate processor set from which said workload is migrated to said target processor set, said source processor set and said target processor set being included in respective distinct computers.
