Abstract

The paper presents an approach to overcome a traditional problem of parallel performance analysis tools: performance data often is too low level and cannot easily be mapped to the application, e.g. its execution phases. The G-PM tool offers the user an easy but flexible means to define his own high-level, application specific metrics based on existing metrics and application events. In a case study based on a real world medical application from the CrossGrid project, we demonstrate this concept as well as its usefulness in practice.
