Abstract
A system for parallel execution of program portions on different processors permits speculative execution of the program portions before a determination is made as to whether there is a data dependency between the portion and older but unexecuted portions. Before commitment of the program portions in a sequential execution order, data dependencies are resolved through a token system that tracks read access and write access to data elements accessed by the program portions.
