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.

Open Petascale Libraries

SESSION: Open Petascale Libraries

EVENT TYPE: Birds of a Feather

TIME: 5:30PM - 7:00PM

SESSION LEADER(S):Ross Nobes, Kenichi Miura, Gerard Gorman

ROOM:TCC LL2

ABSTRACT:
Hardware is evolving to make efficient use of multi-core CPUs. For example, the K Computer features technologies to allow fast inter-core communication, sharing of the programmable L2 cache, and so on. The advent of multi-core computers has led to a re-evaluation of the programming model. The flat MPI approach is sub-optimal, and while PGAS models might offer a solution in the longer term, the best compromise at present is a hybrid model where thread parallelism is used within a node and MPI is used for communication between nodes. Use of numerical libraries that support this model presents a practical way to extract high performance from application codes. Open Petascale Libraries is a global collaboration that aims to promote the development of open-source thread-parallel and hybrid numerical libraries. This session introduces the project, provides an update on progress, and seeks to obtain feedback from the wider community on future directions.
