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: The simulation of the electrophysiology of the heart is a challenging task due to the multiscale nature requiring the use of high spatial and temporal resolutions. Hence it is important to optimize simulation codes for fast execution on contemporary massively-parallel architectures. We have parallelized the well-established realistic heart model PROPAG using a hybrid OpenMP-MPI approach capable of running large-scale simulations with billions of degrees of freedom, which is among the largest problem sizes reported in the literature for this field. We present an in-depth performance analysis of the scalability of our code on up to 8k cores. We demonstrate a performance improvement of 24 - 62% for the multithreaded code and analyze the advantages of the hybrid execution model for this application type.
