ABSTRACT:
A system for prioritizing Input/Output tasks in a computer. The tasks are assigned ranks. When a task is running on the computer, incoming tasks are placed into a queue, in rank order. If the highest-ranking task within the queue outranks the running task, the running task is suspended, and that highest-ranking task is run instead. When that task finishes running, the next-ranking task is run, and so on.
