Abstract: A method and system are disclosed for pre-loading a hard architected state of a next process from a pool of idle processes awaiting execution. When an executing process is interrupted on the processor, a hard architected state, which has been pre-stored in the processor, of a next process is loaded into architected storage locations in the processor. The next process to be executed, and thus its corresponding hard architected state that is pre-stored in the processor, are determined based on priorities assigned to the waiting processes.

Abstract: A method and system are disclosed for managing saved process states in a memory of a data processing system that has multiple partitions executing independent operating systems. A hypervisor manager affords access to any processor in the data processing system for the purpose of storing process states for that processor to the memory, independent of the operating system running on the processor.
