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.

Flexible Resource Allocation for Reliable Virtual Cluster Computing Systems

SESSION: Scheduling and Resource Allocation

EVENT TYPE: Paper

TIME: 2:00PM - 2:30PM

ABSTRACT:
Virtualization and cloud computing make it possible to create virtual high performance computing clusters. This effort, however, is complicated by inherent differences in how these systems allocate resources. Cloud systems immediately allocate resources or deny requests. In contrast, parallel computing systems route all requests through a queue. This divergence of polices hinders efforts to implement efficient, responsive, and reliable virtual clusters. In this paper, we present four scheduling polices and analytical resource prediction models to estimate the resources needed to operate an efficient, responsive, and reliable virtual cluster. We show that it is possible to estimate the size of the virtual cluster needed to provide a predictable grade of service for a high performance computing workload and estimate the queue wait time for a partial or full resource allocation. Moreover, we show that it is possible to provide a reliable virtual cluster system using a limited pool of spare resources.
