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.

Sustained Systems Performance Monitoring at the Department of Defense High Performance Computing Modernization Program

SESSION: State of the Practice - Performance I

EVENT TYPE: State of the Practice

TIME: 11:30AM - 12:00PM


AUTHOR(S):Paul M. Bennett


The U.S. Department of Defense High Performance Computing Modernization Program (HPCMP) has implemented sustained systems performance testing on high performance computing systems in use at DoD Supercomputing Resource Centers. The intent is to monitor performance improvements by updates to the operating system, compiler suites, and numerical and communications libraries, and to monitor penalties arising from security patches. In practice, each system’s workload is simulated by appropriate choices of user application codes representative of the HPCMP computational technical areas. Past successes include surfacing an imminent failure of an OST in a Cray XT3, incomplete configuration of a scheduler update on an SGI Altix 4700, performance issues associated with a communications library update for a Linux Networx Advanced Technology Cluster, and intermittent resetting of Intel Nehalem cores to standard mode from turbo mode. This history demonstrates that SSP testing is critical to deliver the highest quality of service to the HPCMP users.
