Performance Optimization of Parallel Programs - Tracing, Zooming, Understanding -

Alfred Arnold, Ulrich Detert, Wolfgang E. Nagel

Open publisher page 16 citations

Abstract

Performance optimization most often is based on the detailed knowledge of program behavior. One option to get this information is tracing. The visualization environment PARvis developed at KFA translates a given trace file generated on CRAY T3D into a variety of graphical views, e.g., state diagrams, activity charts, timeline displays, and statistics. PARvis supports an animation mode that can help to locate performance bottlenecks, and it provides flex- ible filter operations to reduce the amount of information displayed. Moreover, it has a powerful zooming feature that allows to identify problems at any level of detail.
