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.
ABSTRACT: Very large compute systems are creating unprecedented challenges for the storage systems that support them. This talk will explore some potential solutions to Exascale I/O problems driven by the following trends:
• Stripe sizes continue to expand to achieve speed, but the increase in component failures reduces availability.
• Drive capacities are increasing rapidly, 33% this year alone, but this makes them increasingly vulnerable to triple failures.
• HDD improvements are disproportionate to CPU performance increases and to compensate, disk environments are scaling faster than clusters, with File Systems of 100K HDDs being planned.
• SSDs present an opportunity to address important elements of the Exascale IO challenge, but require architectural changes to effectively exploit.
Problems that are tractable in today's systems will become acute at Exascale and will vastly reduce the value of investment storage infrastructures and the ROI for HPC systems overall.
