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.

End-to-End Performance Problems in High-speed Networks

SESSION: End-to-End Performance Problems in High-speed Networks

EVENT TYPE: Birds of a Feather

TIME: 5:30PM - 7:00PM

SESSION LEADER(S):Constantine Dovrolis, Raj Kettimuthu, Wenji Wu


Achieving efficient data movement over high-speed networks remains an ongoing challenge. Factors that affect end-to-end performance can exist in host systems, within local-area networks, across wide-area paths, and at storage systems. The problem space consists of a highly complex set of layers and domains, including application software, middleware, OS software, system hardware, network software/hardware, file systems and storage. What is worse, the nature of these performance problems is very different, compared to those we are all trained to watch for and diagnose. We need tools that can detect, localize and diagnose transient bottlenecks in complex end-to-end distributed systems. This BoF will focus on the following questions: (1) What are the performance problems that take place in high-end distributed systems? (2) How can such performance problems be detected, diagnosed and localized? (3) How can existing network performance monitoring and diagnosis tools/services scale to high-speed networks?
