Prior work has shown that computing dynamic slices of erroneous program values can greatly assist in locating the root cause of erroneous behavior by identifying faulty statements in sequential programs. These dynamic slices represent backward transitive closure over exercised read-after-write data dependences and control dependences. However, for a multithreaded program executing on a processor,...
We present an online framework to capture and recover from program failures and prevent them from occurring in the future through safe execution perturbations. The perturbations are safe as they respect the semantics of the program. We use a checkpointing/logging mechanism to capture a program execution to an event log. If the execution results in a failure, the framework automatically searches for...
