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.

Deep and Wide Metrics for HPC Resource Capability and Project Usage

ABSTRACT:
This paper defines and demonstrates application of possible quantitative metrics for the qualitative notions of “deep” and “wide” HPC system use along with the related concepts of capability and capacity computing. By summarizing HPC workloads according to the science-oriented projects using the systems, rather than solely on job sizes and distributions, one can identify differences between the workloads on different systems as well as highlight certain instances of unique usage modalities. Specific definitions of depth and width are suggested, along with metrics that permit comparisons to determine which systems are deeper or wider than others. Similarly, the same data permit an alternate means of defining the degree to which HPC system activities are capability- or capacity-oriented.
