Abstract

This article describes a technique used in the input/output (I/O) subsystem of a data processing system that allows for dynamic priority assignment to each I/O operation initiated by a program on single or multiple I/O devices. The priority of an I/O operation is assigned at the time of initiation of the operation to an I/O device.
