Abstract

The evolution of the Web as an enabling tool for e-business introduces a challenge to understanding the execution behavior of largescale middleware systems, such as J2EE, and their commercial workloads. This paper presents a brief description of the whole-stack analysis and optimization system – being developed at IBM Research – for commercial workloads on Websphere Application Server (WAS) – IBM’s implementation of J2EE – running on IBM’s pSeries and zSeries server systems.

Short Biography

Jong-Deok Choi: Jong-Deok Choi is a Research Staff Member (RSM) and Manager of High Performance Programming Environment Group at the IBM T. J. Watson Research Center in Yorktown Heights, New York. He is a project co-leader of the End-to-End Server Optimization project, a cross-organizational effort in IBM for improving the performance of commercial eServer applications on IBM's server platforms. Since joining Watson in 1989, he has been involved in various research and development projects such as PTRAN, TPO, Jalapeno, DejaVu, JikesRVM, and End-to-End Optimization. His research interests include static and dynamic analysis and optimization of commercial and scientific applications, middleware analysis and optimization, high performance computer architecture, and debugging multithreaded and distributed applications.

He received B.S. in Electronic Engineering from SNU, Korea in 1979, M.S. in Electrical Engineering from KAIST, Korea in 1981, and M.S. and Ph.D. both in Computer Sciences from Univ. of Wisconsin-Madison in 1985 and 1989, respectively.
