Abstract From the Canadian patent

Disclosed is a digital computer for processing a program containing an iterative construct. The digital computer comprises a plurality of processors, each adapted for serially processing without the assistance of the other said processors those por-, tions of the program outside of the iterative construct and each adapted for concurrently processing different iterations of the iterative construct. A mechanism is provided for activating those processors that have been idle at the start of the iterative construct and for transferring sufficient state information to the activated processors so that they can begin concurrent processing of iterations.
