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.
Large-scale data visualization for data-intensive and high-dimensional scientific data analysis
SESSION: Doctoral Research Showcase (2 of 2)
EVENT TYPE: Doctoral Research Showcase
TIME: 3:30PM - 3:45PM
SESSION CHAIR: Volodymyr Kindratenko

ABSTRACT: Data-intensive analysis is a challenging task in this so-called data deluge era and large-scale data visualization is highly valuable in many scientific domains as it facilitates scientific discoveries. To utilize the power of the next exascale computing in large-scale data analysis, I have conducted my dissertation research in two main directions: i) Developing large-scale data visualization algorithms for data-intensive and high-dimensional scientific data analysis. ii) Implementing distributed and parallel algorithms with efficient use of distributed computing resources, including high-performance clusters, grids, and cloud systems. To this end, I have built a large-scale visualization system which consists of a set of high-performance parallel dimension reduction algorithms and a light-weight 3D point visualization client, named PlotViz, with which users can navigate large number of data in a virtual 3D space. This visualization system has been successfully applied to real-life data mining projects including a drug discovery project and a chemogenomic data mining.
