Leveraging Hardware-Assisted Virtualization for Deterministic Replay on Commodity Multi-Core Processors.

Deterministic replay, which provides the ability to travel backward in time and reconstruct the past execution flow of a multiprocessor system, has many prominent applications. Prior research in this area can be classified into two categories: hardware-only schemes and software-only schemes. While hardware-only schemes deliver high performance, they require significant modifications to the existin...
