ABSTRACT:
A method for processing timer requests efficiently by reducing overhead and by increasing scalability within a computer system is disclosed. A timer request having a wake-up time of moderate length and a high tolerance level such that the wake-up time does not have to be very precise, is placed in a drop-off queue which is made up of an unsorted double-linked list. The timer request is then periodically hashed from the drop-off queue into an appropriate element of a timer request array, according to the time duration of the timer request. The timer request array is then of the timer request array. Finally, the timer request is awakened when request array with no time remaining.
