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: Large scientific applications deployed on current petascale systems expend a significant amount of their execution time dumping checkpoint files to remote storage. New fault tolerant techniques will be critical to efficiently exploit post-petascale systems. In this work, we propose a low-overhead high-frequency multi-level checkpoint technique in which we integrate a highly-reliable topology-aware Reed-Solomon encoding in a three-level checkpoint scheme. We efficiently hide the encoding time using one Fault-Tolerance dedicated thread per node. We implement our technique in the Fault Tolerance Interface FTI. We evaluate the correctness of our performance model and conduct a study of the reliability of our library. To demonstrate the performance of FTI, we present a case study of the Mw9.0 Tohoku Japan earthquake simulation with SPECFEM3D on TSUBAME2.0. We demonstrate a checkpoint overhead as low as 8% on sustained 0.1 Petaflops runs (1152 GPUs) while checkpointing at high frequency.
