SC is the International Conference for
High Performance Computing, Networking,
Storage and Analysis

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.

Scalable Infrastructure to Support Supercomputer Resiliency-Aware Applications and Load Balancing

ROOM:WSCC North Galleria 2nd/3rd Floors

Current trends dictate increasing complexity and component counts on supercomputers and mainstream commercial systems alike. This trend exposes weaknesses in the underlying clustering infrastructure needed for continuous availability, maximizing utilization, and efficient administration of such systems. We propose a step to alleviate this problem by providing a highly scalable clustering infrastructure, based on peer-to-peer technologies, for supporting resiliency-aware applications as well as efficient monitoring and load balancing. Supported services include Membership, supporting resiliency-aware applications, publish-subscribe messaging, Convergecast supporting load balancing schemes, attributes dissemination for propagating slowly changing information, and DHT facilitating services discovery and integration. We employ a flexible two layer hierarchical topology, comprised of base zones federated by a management zone. Our design aspires to quickly identify membership changes in a scalable environment with minimal overall system disruption, thus enabling efficient Exascale size deployments. We present experimental evaluation taken from an IBM BlueGene/P, demonstrating scalability up to ~256K nodes.
