Abstract

An incremental method is described for distributing the instructions of an execution sequence among a plurality of processing elements for execution in parallel. The distribution is based upon anticipated availability times of the needed input values for each instruction as well as the anticipated availability times of each processing element for handling each instruction. A self-parallelizing computer system and method are also described for asynchronously processing the distributed instructions in two modes of execution on a set of processing elements which communicate with each other.
