Abstract
An intelligent disk drive is described which includes means for executing 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. A method of organizing data for distributed processing in the intelligent disk drive is described which utilizes physical placement of the data around the rotating disk to optimize the execution of the task. In one embodiment head switching is used as further optimization in a disk drive having a plurality of heads to implement alternatives in the task program. In another embodiment, the intelligent disk drive has means for reading from at least one or more heads simultaneously while writing to another head.
