Abstract

This article presents a class library for detecting typical performance problems in event traces of MPI applications. The library is implemented using the powerful high-level trace analysis language EARL and is embedded in the extensible tool component EXPERT described in this paper. One essential feature of EXPERT is a flexible plug-in mechanism which allows the user to easily integrate performance problem descriptions specific to a distinct parallel application without modifying the tool component.
