Abstract: A method for performing debugging of an executable source program in a massively parallel processing environment involves associating a major cycle counter and a minor cycle counter with each of a plurality of execution processors in the massively parallel processing environment, obtaining a first stopping point value associated with the major cycle counter and a second stopping point value associated with the minor cycle counter, executing instructions of the executable source program on each of the plurality of execution processors, modifying the major cycle counter and the minor cycle counter, and halting each of the plurality of execution processors and returning control to the user if the major cycle counter reaches the first stopping point value and the minor cycle counter reaches the second stopping point value.

Abstract: The present invention provides a method and apparatus for statement boundary detection. In one embodiment of the present invention, a parser determines a natural end of a statement, where possible, based upon the context of the input stream and the syntax of the programming language. Thus, no statement terminator is necessary when a natural end to a statement is determined. The parser uses the natural end of a statement to terminate one statement and begin parsing another statement. In one embodiment, a special statement termination token is required to terminate a statement when no natural statement end exists. In another embodiment, a special statement termination token can be used to terminate a statement when a natural end of the statement exists.
