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.

ABSTRACT: Computational resources on modern high-performance computers are underutilized mainly due to hardware and software performance bottlenecks. Identification of such bottlenecks is primary goal of performance analysis, and performance tools are essential for this purpose. In this poster, we demonstrate a case study of the use of the TAU Toolkit to tune the front tracking CFD application FronTier on Argonne's IBM Blue Gene/P supercomputer and scale it to entire system with 62% efficiency on 163,840 cores. The main improvements are related to enhancements of point-to-point communication pattern, reduction of the number of collective operations, and removal of unnecessary synchronization. FronTier is the main computing code for our study of uncertainty quantification for turbulent mixing as part of the DOE INCITE 2011 award.
