Abstract
A disk drive is described which executes distributed computing tasks including a CPU and associated memory. The communication interface with the host computer is modified to allow the host computer to send executable code for a task to the drive and to allow the drive to communicate the results and status information about the task to the host computer. In a preferred embodiment the disk drive has a task control program, task program code, task data and status information for the distributed task. In alternative embodiments, the disk drive can communicate with other similar disk drives in the bus to provide the results of computation to the other processors. The RAM memory, and mass storage are intimately connected through the associated hard disk controller such that the exact location of the required data and program instructions are known.
