Abstract

Performance analysis most often is based on the detailed knowledge ofprogram behavior, One option to get this information is tracing. Based on the research tool PARvis, the visualization environment VAMPIR was developed at KFA which now supports the new message passing standardMPI, VAMPIR translates a given trace file into a variety of graphicalviews, e.g., state diagrams, activity charts, time-line displays, andstatistics. Moreover, it supports an animation mode that can help to locate performance bottlenecks, and it provides flexible filter operations to reduce the amount of information. displayed. The most interesting part of VAMPIR is the powerful zooming feature that allows to identify problems at any level of detail.
