This paper describes the VAMPIR-environment which provides some powerful features to discover parallel program behavior on several parallel systems like Intel Paragon and CRAY T3D. Experience has shown, that for debugging, as well as for performance optimization purposes, the supported time-line displays in combination with the statistics features are the strength of the system. With the extremely flexible zooming function in the time-line displays, analysis operations are supported which can drastically improve the understanding of observed performance problems.
VAMPIR is available as a commercial product from PALLAS GmbH; for
