报告题目：Accelerating Big Data Applications in Cloud Data Centers

报告摘要：

Large-scale cloud data centers leverage virtualization to achieve high resource utilization, scalability, and availability. While ideally the performance of an application running inside a virtual machine (VM) shall be independent of co-located applications and VMs that share the physical resources, current systems are yet to achieve this goal. In this talk, I will describe our efforts in addressing a number of computer system challenges in order to achieve optimal I/O performance in such virtualized systems. Specifically, 1) TRACON constructs mathematical models and scheduling algorithms to mitigate the VM interference; 2) Matrix leverages machine learning and optimization techniques to allocate VM resource in a way that minimizes the cost while achieving good application performance; and 3) Mortar enhances the hypervisor to pool together spare memory on each machine and expose it as a volatile data cache to improve virtual I/O performance.
