7 Summary

In this tutorial, we have shown how to use PPW to analyze the GWU UPC implementation of the NPB2.4 IS benchmark, and how to use PPW to generate trace data that can be viewed with the Jumpshot trace visualization tool. We hope that we have inspired you to try out our tool, which is available from the PPW website. If you found this information useful, you might check out the PPW user manual, which is also available from the aforementioned website.

Conspicuously absent from this tutorial are specific instructions on how to optimize this benchmark based on the information discovered from using PPW. This is left as an exercise for the reader :-)

Finally, we are actively seeking feedback on our tool. If you find PPW useful or annoying, please drop us a line at ppw AT hcs DOT ufl DOT edu.
