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.
Performance Evaluations of Gyrokinetic Eulerian Code GT5D on Massively Parallel Multi-Core Platforms

ABSTRACT: A gyrokinetic toroidal five dimensional Eulerian code GT5D [Y.Idomura et. al., Comput. Phys. Commun 179, 391 (2008)] is ported on five advanced massively parallel platforms and comprehensive benchmark tests are performed. Sustained performances of the GT5D kernel and their dependency on the memory bandwidth are discussed. By using a novel multi-layer hybrid parallelization model, the size of MPI communicators can be suppressed below ~100 up to ~10^7 cores, and the scalability is improved on multi-core platforms. In strong scaling tests, a good scalability is confirmed up to several thousands cores on every platforms, and the maximum sustained performance of ~19.4 Tflops (the peak ratio of ~10.1%) is achieved using 16384 cores of BX900.
