ABSTRACT:
A method (and apparatus) of determinstically replaying an observable run-time behavior of distributed multi-threaded programs on multiprocessors in a shared-memory multiprocessor environment, wherein a run-time behavior of the programs includes sequences of events, each sequence being associated with one of a plurality of execution threads, includes identifying an execution order of critical events of the program, wherein the program includes critical events and non-critical events, generating groups of critical events of the program, generating, for each given execution thread, a logical thread schedule that identifies a sequence of the groups associated with the given execution thread, and storing the logical thread schedule for subsequent reuse.
