Abstract
Interrupt-intensive and interrupt-driven processes are managed among a plurality of virtual processors, wherein each virtual processor is associated with a physical processor, wherein each physical processor may be associated with a plurality of virtual processors, and wherein each virtual processor is tasked to execute one or more of the processes, by determining which of a plurality of the processes executing among a plurality of virtual processors are being or have been driven by at least a minimum count of interrupts over a period of operational time; selecting a subset of the plurality of virtual processors to form a sequestration pool; migrating the interrupt-intensive processes on to the sequestration pool of virtual processors; and commanding by a computer a bias in delivery or routing of the interrupts to the sequestration pool of virtual processors.
