Abstract
Methods, computing systems and computer program products implement embodiments of the present invention that include identifying a first number of processors in a computer, and identifying a second number of interrupt request (IRQ) lines on a hardware acceleration device in the computer and coupled to the processors, the second number greater than or equal to the first number. Each of the IRQ lines is associated with one of the processors, and upon selecting a given IRQ line for an application thread, a given processor associated with the given IRQ line is identified. Execution of the application thread is initiated on the given processor, and using the given IRQ line, a completion queue is configured for the application thread. If the thread is executing on a different processor than the one managing the completion queue, then the management of the completion queue can be migrated to the processor executing the thread.
