Performance Analysis Using SvPablo

In this tutorial we present SvPablo, a graphical source code browser and performance visualizer that integrates the University of Illinois Pablo project's dynamic performance instrumentation software with HPF and C compilers and with the MIPS R10000 hardware performance mechanism. The following topics will be covered in the tutorial: an introduction to the SvPablo environment, including an overview of the Self-Deening Data Format, used to store the performance les; the instrumentation and visualization of HPF and C programs; the integration with the MIPS R10000 hardware performance counters; and nally an experiment using a real life application running on an SGI Origin 2000, that demonstrates the usefulness of SvPablo for tuning application programs.
