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: Hadoop has become the de-facto platform for large-scale analysis in commercial applications, and increasingly so in scientific applications. However, applying
Hadoop's byte-stream data model causes inefficiencies when used for scientific data that is stored in highly-structured, binary file formats. This limits the scalability of Hadoop applications in science. We introduce SciHadoop, a Hadoop
plugin allowing scientists to specify logical queries over array-based data models. SciHadoop executes these queries as map/reduce programs defined over the logical data model. We describe the implementation of a SciHadoop prototype for netCDF data sets, and quantify the performance of three effective optimizations: the first optimization minimizes network traffic by intelligently partitioning the input space of mappers at the logical level; the second optimization avoids full-scans by pruning partitions using knowledge of query data dependencies; the third optimization minimizes data transfers by processing holistic aggregation functions (e.g. median) at mappers instead of reducers whenever possible.
