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.

Minimizing End-To-End Interference in I/O Stacks Spanning Shared Multi-Level Buffer Caches

SESSION: Doctoral Research Showcase (1 of 2)

EVENT TYPE: Doctoral Research Showcase

TIME: 1:30PM - 1:45PM

SESSION CHAIR: Volodymyr Kindratenko

Presenter(s):Christina M. Patrick


I focus on multi-level shared buffer cache hierarchies accessing shared storage servers attached to shared disks. This is the most common type of storage model found in data centers, clouds, clusters etc. Managing shared buffer caches in multi-level buffer cache hierarchies as well as shared disks in these I/O stacks is a challenge for any researcher. The numerous interactions that disturb the performance in this scenario are difficult to isolate and address. The biggest hurdle in such I/O stacks is that they are not designed to combat inter-application interference. This inter-application interference deteriorates the performance of the shared buffer caches as well as the shared disks severely. I am designing a superior I/O stack which is application and disk characteristic aware and exploits this knowledge to employ a set of unique solutions which will maximize application performance by minimizing the inter-application interference throughout the buffer caches and the disks.
