 The second goal of project is to improve techniques for mitigating information traffic jams--what computer specialists call "performance debugging."  Traditional tools for performance debugging have not scaled to large parallel machines because it is difficult to decide in advance what to measure and in what detail.  Our tools transcend this problem by supporting "dynamic instrumentation" that allows measurement activity to adapt to the tool's current hypothesis for the information traffic jam's location.
