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: Chapel is a high-level parallel programming language that implements
a partitioned global address space model (PGAS). On our poster, we
will present BRAID, which enables Chapel programs to call functions
and instantiate objects written in C, C++, Fortran 77 - 2008, Java
and Python. Our tool creates language bindings that are
binary-compatible with Babel.
The scientific community maintains a large amount of code written in
traditional languages. With the help of our tool, users will gain
access to their existing codebase with minimal effort. The language
bindings are designed to provide a good combination of performance
and flexibility (including transparent access to distributed
The advantages of our approach are highlighted by benchmarks that
compare the performance of pure Chapel programs with that of hybrid
versions that call subroutines implemented in Babel-supported
languages inside of parallel loops. We also present our vision for
interoperability with other PGAS languages such as UPC and X10.
