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.

A Merge-and-Split Mechanism for Dynamic Virtual Organization Formation in Grids

SESSION: ACM Student Research Competition Poster Session

EVENT TYPE: ACM Student Research Competition Poster

TIME: 5:15PM - 7:00PM

SESSION CHAIR: Bernd Mohr

ROOM:WSCC North Galleria 2nd/3rd Floors

ABSTRACT:
Executing large scale application programs in grids require resources from several Grid Service Providers (GSPs). These providers form Virtual Organizations (VOs) by pooling their resources together to provide the required capabilities to execute the application. We model the VO formation in grids using concepts from coalitional game theory and develop a novel framework and a mechanism for VO formation. The mechanism enables the GSPs to self-organize into VOs reducing the cost of execution and guaranteeing maximum profit for the GSPs. Furthermore, the mechanism guarantees that the VOs are stable, that is, the GSPs do not have incentives to break away from the current VO and join some other VO. We perform extensive simulations to characterize the properties of the proposed algorithm. The results show that the algorithm produces VOs that are stable yielding high revenue for the participating GSPs. We plan to prepare a 4'X3' poster.
