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 LSST project will provide public access to a database catalog
that, in its final year, is estimated to include 26 billion stars and
galaxies in dozens of trillion detections in multiple
petabytes. Because we are not aware of an existing open-source
database implementation that has been demonstrated to efficiently
satisfy astronomers' spatial self-joining and cross-matching queries
at this scale, we have implemented Qserv, a distributed shared-nothing
SQL database query system. To speed development, Qserv relies on two
successful open-source software packages: the MySQL RDBMS and the
Xrootd distributed file system. We describe Qserv's design,
architecture, and ability to scale to LSST's data requirements. We
illustrate its potential with test results on a 150-node using 55
billion rows and 30 terabytes. These results demonstrate the
soundness of Qserv's approach and the scale it achieves on today's
hardware.
