This poster describes a visualization tool that uses polar coordinates to create a circular shaped layout of larg e call trees of Strand programs. Due to the enormous amount of pro- cesses which are generated during execution of parallelStrand programs, conventional techniques to display call trees ar e over- charged. Out of this motives the toolPolaranimation' was d veloped and implemented. One of its prominent features is th e ability to display the complete call tree without loosing an y vi- tal information. Additionally, it provides debugging faci lities and supports the performance tuning of parallel programs. A num ber ofStrand programs have been written and a performance evalua- tion and comparison guided byPolaranimation' was conduct ed. Keywords—Software Visualization, Strand, Parallel Logic Programming, Debugging.
