SCHEDULE: NOV 12-18, 2011

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.

Performance Analysis of a Parallel Linear Octree Finite Element Mesh Generation Scheme

SESSION: Research Poster Reception

EVENT TYPE: ACM Student Research Competition Poster, Poster, Electronic Poster

TIME: 5:15PM - 7:00PM

SESSION CHAIR: Bernd Mohr

AUTHOR(S):Jose Camata, Renato Elias, Alvaro Coutinho

ROOM:WSCC North Galleria 2nd/3rd Floors

ABSTRACT:
We show a performance analysis of a parallel octree-based mesh generation scheme designed to create reasonable-quality, geometry-adapted unstructured hexahedral meshes automatically from triangulated surface models. We present algorithms for the construction, 2:1balancing and meshing large linear octrees on supercomputers. Our scheme uses efficient computer graphics algorithms for surface detection,allowing us to represent complex geometries. An isogranular analysis demonstrates good scalability. Our implementation is able to execute the 2:1balancing operations over 3.4 billion octants in less than 10 seconds per 1.6 million octants per CPU core.
