Multi-stage replay with crosscut

Deterministic record-replay has many useful applications, ranging from fault tolerance and forensics to reproducing and diagnosing bugs. When choosing a record-replay solution, the system administrator must choose a priori how comprehensively to record the n and at what abstraction level to record it. Unfortunately, these choices may not match well with how the recording is eventually used. A recording may contain too little information to support the end use of replay, or it may contain more sensitive information than is allowed to be shown to the end user of replay. Similarly, the abstraction level at the time of recording often leads to a semantic mismatch with the end use of replay. This paper describes how to remedy these problems by adding customizable replay stages to create special-purpose logs for the end users of replay. Our system, called Crosscut, allows replay logs
