Abstract
A method and system for processing an input/output request on a multiprocessor computer system comprises pinning a process down to a processor issuing the input/output request. An identity of the processor is passed to a device driver which selects a device adapter request queue whose interrupt is bound to the identified processor and issues the request on that queue. The device accepts the request from the device adapter, processes the request and raises a completion interrupt to the identified processor. On completion of the input/output request the process is un-pinned from the processor. In an embodiment the device driver associates a vector of the identified processor with the request and the device, on completion of the request, interrupts the processor indicated by the vector.
