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.

How to Measure Useful, Sustained Performance

SESSION: State of the Practice - Performance I

EVENT TYPE: State of the Practice

TIME: 11:00AM - 11:30AM

SESSION CHAIR: David Paul

ROOM:TCC 202

ABSTRACT:
Sustained performance is the amount of useful work a system can produce in a given amount of time on a regular basis. How much useful work a system can achieve is difficult to assess in a simple, general manner because different communities have their own views of what useful work means and because a large number of system characteristics influence its usefulness. Yet, we, as a community, intuitively, and sometimes explicitly, know when a system is more useful than another. On the other hand, we also know when measures do not accurately portray a system's usefulness. This report will review the important concepts of measuring sustained performance, discuss different approaches for doing the measurements and point out some of the issues that prevent our community from developing common, effective measures.
