Keynote: Automated Modeling of Complex Data Center Applications

Prashant Shenoy, University of Massachusetts School of Computer Science

Prashant Shenoy

Abstract:

As online services become increasingly common, the complexity of backend distributed server applications in data centers has also continued to grow. At the same time, there is an increasing need to enhance the manageability of these large applications by automating common management tasks, which requires a good understanding of the run-time behavior of the application under different scenarios. However, the rising complexity of these applications makes the tasks of manually modeling and analyzing their run-time behavior increasingly difficult. In this talk, I will argue for the need to automate the modeling of the run-time performance of distributed data center applications. I will present techniques for automatically deriving application models using statistical methods from machine learning. I will describe how we have put these ideas into practice into two systems that we have built, Modellus and Predico, and will present case studies of using these systems for management tasks such as capacity planning and what-if analysis of data center applications.

Keynote: Supporting Operations Personnel Through Performance Engineering

Len Bass, NICTA, Australia

Len Bass

Abstract:

Operations costs are around 50% of the worldwide costs of Information Technology. Yet operations problems are mainly viewed as the problem of IT and not of the problem of product developers or performance engineers. I will discuss some areas where performance engineers could be of great assistance to operations and where an understanding of  operations process could inform the models created by performance engineers.

Keynote: Data Centric Computing for Internet Scale Enterprises

Yuqing Gao, IBM T. J. Watson Research Center, US

Yuqing Gao

Abstract:

In the internet and mobile era, enterprises are facing both the challenge and business opportunities that introduced by Big Data, which has the characteristics of high volume, high velocity, and high variety. Big Data and the emergence of Internet-facing transactional workloads will blur the separation between traditional transactional and analytics workloads. To extract business value and make actionable insight from the unprecedented volume of the data at a rate up to 10,000 times faster than traditional systems, data centric computing becomes necessary to prevent the movement of Big Data that can often swamp the actual processing time for the application, dominating performance cost. In this talk, I will talk those technologies that are recently built at IBM Research to address challenges in design data centric computing systems, particularly, in the area of data access latency, data ingestion, and massive scale-out distributed caching in the exemplary context of an online product recommendation application. I will talk an innovative distributed caching system that exploits low latency interconnects to utilize hash maps of data keys on each server for local lookup while data resides and are accessed across clustered systems. The distributed cache can achieves 100 to 1000-fold performance gain over many caching methods.

Biography:

Dr. Gao is a senior manager and a Research Staff Member at IBM T. J. Watson Research Center, where she is a PI for the Data Centric Computing Strategic Initiative, leading the development of massive scale infrastructure middleware for data-centric systems. She is a co-PI for the Workload Optimized Systems Strategic Initiative. She headed the Laboratory for Speech to Speech Translation Systems at IBM in 2006-2007. She was the principal investigator of DARPA CAST and TransTac Programs at IBM in 2001-2008, and led research and development of IBM MASTOR (Multilingual Automatic Speech-to-Speech Translator) systems, which received exceptional reviews for its superior accuracy and robustness, speed and memory efficiency. She received the IEEE Signal Processing Society Best Paper Award for her paper “Maximum entropy direct models for speech recognition” in 2007, & won two awards from DARPA for her exemplary work & breakthroughs in the application of translation technology in military and homeland security areas. In 2004, Dr. Gao’s work was recognized by MIT’s Technology Review Magazine as one of the “Ten emerging technologies that will change your world”. In 2005, her work was a cover story about “What’s Next” in Time magazine. She was featured by CNN, ABC, BBC and many major media. She received IBM Corporate Award, Outstanding Innovation Awards and Research Division Awards. She is a member of IBM Academy of Technology, an IEEE Fellow, published over 120 papers, holds over 30 issued patents.
