EARL - A programmable and extensible toolkit for analyzing event traces of message passing programs

Abstract

This paper describes a new meta-tool named EARL which consists of a new high-level trace analysis language and its interpreter which allows to easily construct new trace analysis tools. Because of its programmability and flexibility, EARL can be used for a wide range of event trace analysis tasks. It is especially well-suited for automatic and for application or domain specific trace analysis and program validation. We describe the abstract view on an event trace the EARL interpreter provides to the user, and give an overview about the EARL language. Finally, a set of EARL script examples are used to demonstrate the features of EARL.
