Estimating the term…
Exemplary embodiments include a system and storage medium for managing computer processing functions in a multi-processor computer environment. The system includes a physical processor, a standard logical processor, an assist logical processor sharing a same logical partition as the standard logical processor, and a single operating system instance associated with the logical partition, the single operating system instance including a switch-to service and a switch-from service. The system also includes a dispatch component managed by the single operating system instance. Upon invoking the switch-to service by standard code, the switch-to service checks to see if an assist logical processor is online and, if so, it updates an integrated assist field of a work element block associated with the task for indicating the task is eligible to be executed on the assist logical processor. The switch-to service also assigns a work queue to the work element block.
A method for managing computer processing functions in a multi-processor computer environment, said multi-processor computer environment including at least one first processor and at least one second processor, each of which is managed by operating system software, said method comprising:
A storage medium including machine-readable computer program code for managing computer processing functions in a multi-processor computer environment, said multi-processor computer environment including at least one first processor and at least one second processor, each of which is managed by operating system software, said storage medium including instructions for causing a computer to implement a method, comprising:
A method for managing computer processing functions in a multi-processor computer environment, said multi-processor computer environment including at least one first processor and at least one second processor, said method being performed by a switch-to service and comprising:
A storage medium including machine-readable computer program code for managing computer processing functions in a multi-processor computer environment, said multi-processor computer environment including at least one first processor and at least one second processor, said storage medium including instructions for causing a computer to implement a method, said method being performed by a switch-to service and comprising:
