Record and deterministic replay of parallel programs on multiprocessors
Record and deterministic Replay (RnR) is a primitive with many proposed applications in computer systems, including debugging, security and fault tolerance. RnR is typically a two phase process: in the first phase (record) enough information about an execution is logged which is then used in the …

Practical Time Travel of Multiprocessor Systems
… and is possible using a technique called Deterministic Replay of Execution. This thesis presents DeLorean, a novel hardware substrate for deterministic replay of multiprocessor systems. DeLorean advances the state of the art in that it enables high-speed recording and replay of parallel …

Detecting And Mitigating Concurrency Bugs
… many ways, a parallel program may produce a non-deterministic outcome even for identical program inputs if threads are not properly synchronized. Such a non-deterministic behavior, if not intentional, is often referred to as a concurrency bug. In this research, a solution is presented for …

Record and replay based virtual-machine introspection for system security
… This decomposition is enabled with Record and Deterministic Replay. The original execution is recorded and subjected to replay analysis as alarms are raised. In this way the Replay infrastructure can compensate for the occasional hardware imprecision. We demonstrate this approach by applying it …

Leveraging concurrency for performance and security
… Concurrency Accelerator (ConcAcl), Record-and-Replay Safe (RnRSafe), ReplayConfusion, and ReplayEndurance. With ConcAcl we accelerate concurrency management operations by creating a dedicated layer that is programmed by supervisor software (e.g. Operating System kernels or multi-threading …
