Abstract
This article describes properties, design and implementation of PATOP (Performance Analysis TOol for Parallel systems). It was developed as part of the TOPSYS project at Technical University of Munich. Its purpose is to make the efficiency of parallel programs visible, in order to find performance bottlenecks (performance debugging). PATOP was implemented on the IPSC/2 Hypercube. It supports measurements on the system's hardware structure (whole system, processor nodes, communication links) and on objects of the programming model (Task, Mailbox, Semaphore). Measurements can be started and evaluated during program execution (on-line). User interaction is menu driven and measurement results are displayed graphically.
