In mathematics and computer science, a trace is a set of strings, wherein certain letters in the string are allowed to commute, but others are not. It generalizes the concept of a string, by not forcing the letters to always be in a fixed order, but allowing certain reshufflings to take place. Traces are used in theories of concurrent computation, where commuting letters stand for portions of a job that can execute independently of one-another, while non-commuting letters stand for locks, synchronization points or thread joins.
