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.
Auto-Scaling to Minimize Cost and Meet Application Deadlines in Cloud Workflows
SESSION: Scheduling and Resource Allocation
EVENT TYPE: Paper
TIME: 2:30PM - 3:00PM
AUTHOR(S):Ming Mao, Marty Humphrey
ABSTRACT: A goal in cloud computing is to allocate only those cloud resources that are truly needed. To date, cloud practitioners have pursued schedule-based and rule-based mechanisms to attempt to automate this matching between computing requirements and computing resources. However, most of these “auto-scaling” mechanisms only support simple resource utilization indicators and do not specifically consider both user performance requirements and budget concerns. In this paper, we present an approach whereby the basic computing elements are virtual machines (VMs) of various sizes/costs, jobs are specified as workflows, users specify performance requirements by assigning (soft) deadlines to jobs. The goal is to ensure all jobs are finished within their deadlines at minimum financial cost. We accomplish our goal by dynamically allocating/deallocating VMs and scheduling tasks on the most cost-efficient instances. We evaluate our approach in four representative cloud workload patterns and show cost savings from 9.8% to 40.4% compared to other approaches.
