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.
Server-Side I/O Coordination for Parallel File Systems
SESSION: Coordinating I/O
EVENT TYPE: Paper
TIME: 1:30PM - 2:00PM
AUTHOR(S):Huaiming Song, Yanlong Yin, Xian-He Sun, Rajeev Thakur, Samuel Lang
ABSTRACT: Parallel file systems have become a common component of modern high-end computers. However, current parallel file systems lack the ability to effectively handle concurrent I/O requests with data synchronization needs, whereas concurrent I/O requests are the norm in data-intensive applications. Recognizing that an I/O request will not complete until all involved file servers have completed their parts, in this paper we propose a server-side I/O coordination scheme for parallel file systems. The basic idea is to coordinate file servers to serve one application at a time in order to reduce the completion time, and in the meantime maintain the server utilization and fairness. We present the I/O coordination algorithm and its corresponding analysis of completion time. We also implement a prototype of the proposed scheme under the PVFS2 file system and MPI-IO environment. Experimental results demonstrate that the proposed scheme can reduce average completion time by 8% to 46%.
