Performance Prediction and Optimization using Linux/Cgroups

Date: Wednesday, June 1st
Time: 1:00pm
Location: Room 502

With the progress of server consolidation, we tend to operate important applications (APs) and normal APs in the same server. The important APs need the real-time performance and IO performance strictly. In this presentation, I propose the resource optimized method which predicts I/O throughput and latency with regression analysis and feedback function. I evaluate Linux/cgroups in latency and IO throughput with fio benchmark. This method can optimize the computing resources according to each AP requirement. This is my first submit to LinuxCon. In the cloud computing with recent interest, the enhancement of resource management and security is required. I propose Linux/cgroups extensions for persons interested in Linux kernel developer and cloud computing. I make the problem of Linux/cgroups (ex. performance prediction and access control with performance) clear and promote this development. Then I enlarge the field of Linux/cgroups for cloud computing and want to contribute to the spread of Linux.

Yuzuru Maya received a B.E. in Electronics Engineering from Ehime University and joined Hitachi, Ltd. in 1980. He researched private branch exchange systems and high availability methods for distributed computer systems. He received a Ph.D. degree in engineering from Ehime University in 2000 on high-availability system on distributed computer systems. After research and development on NAS (network attached storage) based on Linux and secure operating systems, he researched secure platform which consists of Xen and access control. Maya has been working on Linux/cgroups which consists of resource management and access control since April 2010, and propose enhanced cgroups functions related to cloud computing. He is a member of the Information Processing Society of Japan (IPSJ) and the Institute of Electronics, Information and Communication Engineers (IEICE).
