Memory Optimization and Debugging on Multi- and Many- Core Systems

SESSION: Debugging Tools

EVENT TYPE: Exhibitor Forum

TIME: 4:30PM - 5:00PM

Presenter(s):Chris Gottbrath

ROOM:WSCC 611/612

This talk outlines some development challenges on clusters based on multi- and many-core node architectures and in clusters with GPU co-processors. It highlights three tools that make tackling those challenges easy: ThreadSpotter, TotalView, and ReplayEngine. The ThreadSpotter cache memory optimization tool simplifies finding, understanding and resolving memory bandwidth and cache coherency issues, including false sharing. Problems that usually require a guru are now solvable, and if you do happen to be a performance guru you'll be able to solve them really quickly. The TotalView scalable graphical debugger provides the control and visibility into hybrid and GPU-accelerated MPI applications that you need to make short work of crashes, hangs, deadlocks, and out-of-memory problems. With the ReplayEngine reverse debugging add-on even intermittent race condition type problems become tractable. We’ll cover the key features that make these tools indispensable in multicore and GPU development.
