Summary:Embodiments herein are directed to parallel replay of code execution. An embodiment parses trace data comprising a plurality of trace data streams that each represents execution of a corresponding one of a plurality of executable entities, and identifies a plurality of trace sections that each represents one or more events executed by one of the executable entities over a period of time. The embodiment defines an ordering among the trace sections, identifies a point of interest in at least one of the executable entities, and identifies a subset of the trace sections that, when replayed linearly according to the ordering, would encounter the point of interest. The embodiment queues the subset of trace sections in an execution pool for replay by one or more processors. Then, based on the trace data, the embodiment uses the processor(s) to replay two or more of the subset of trace sections in parallel.
