When viewing the Technical Program schedule, on the far righthand side
is a column labeled "PLANNER." Use this planner to build your own
schedule. Once you select an event and want to add it to your personal
schedule, just click on the calendar icon of your choice (outlook
calendar, ical calendar or google calendar) and that event will be
stored there. As you select events in this manner, you will have your
own schedule to guide you through the week.
You can also create your personal schedule on the SC11 app (Boopsie) on your smartphone. Simply select a session you want to attend and "add" it to your plan. Continue in this manner until you have created your own personal schedule. All your events will appear under "My Event Planner" on your smartphone.
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
ABSTRACT: 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.
