Efficient Transaction-Based Deterministic Replay for Multi-threaded Programs
Existing replay techniques record inter-thread access event orders on shared memory locations to facilitate replay. Some techniques propose strategies to reduce the recorded events often at the expense of deterministic trace reproduction. We propose a technique based on the division of a thread’s execution trace into sequential code blocks called transactions. Our insight is that there are usually few to no atomicity violations reported during a program execution. Based on our insight, we present TPLAY, a novel deterministic replay technique which records thread access interleavings on shared memory locations at a transactional level. TPLAY also generates an artificial pair of interleavings when an atomicity violation is reported on a transaction. We present an experiment and analyze the results of our experiment using the Splash2x extension of the PARSEC benchmark suite. The experimental results indicate that on average, TPLAY experiences a 13-fold improvement in record log sizes and achieves 98% replay probability on subject programs in comparison to existing work.
