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 economy of scale offers cloud computing unlimited cost effective processing potentials. Theoretically, prices under fair market conditions should reflect the most reasonable costs of computations. The fairness is in theory ensured by the market forces. While there is no lack of incentives for the cloud provider to offer auction-based computing platform, using these volatile platform for practical computing is a challenge. This paper reports a methodology and a toolkit designed to tame the challenges for MPI applications.
We introduce a formal model, then a HPC application toolkit, named SpotMPI, to facilitate the practical execution of real MPI applications on volatile auction-based cloud platforms. Our models capture the intrinsic dependencies between critical time consuming elements by leveraging instrumented performance parameters and publically available resource bidding histories. We study algorithms with different computing v.s. communication complexities. Our results show non-trivial insights into the optimal bidding and application scaling strategies.
