KOJAK

The KOJAK (Kit for Objective Judgement and Knowledge-based Detection of Performance Bottlenecks) is a set of generic and interoperable tool components designed for the performance analysis of parallel applications. Their functionality addresses the entire analysis process including instrumentation, postprocessing of performance data, and result presentation. Particular emphasis is put on automation techniques to transform the collected data into a high-level view of performance behavior. An essential part of the software constitutes an integrated event-trace analysis environment for MPI and OpenMP applications.
