The hardest step in solving software bugs in a parallel programming environment centers on working backward from a software failure to the original program error. Conventional debugging techniques allow users to control program execution only in the forward direction, forcing developers to apply time-consuming methods to attempt to identify the problem. Reverse debugging technologies have the potential to greatly reduce the time required to identify and solve many of the most difficult bugs by adding the ability to replay parallel program execution.
