Abstract
Many areas of computer performance analysis require detailed traces of events that occur during a program's execution. Collecting traces is expensive. The additional code required to record events greatly slows a program's execution. In addition, the resulting trace files can grow unmanageably large. This paper describes a technique called abstract execution that alleviates both problems.Abstract execution records a small set of events during the traced program's execution. These events serve as input to an abstract version of the program that generates a full trace by re‐executing selected portions of the original program. This process greatly reduces both the cost of tracing the original program and the size of the trace files. The cost of regenerating a trace is insignificant in comparison to the cost of applications that use it.This paper also describes a system called AE that implements Abstract Execution. The paper contains measurements that demonstrate that AE can efficiently trace large programs.
