Biographical sketches of authors

Sandra Johnson Baylor   IBM Research Division, Thomas J. Watson Research Center, P.O. Box 704, Yorktown Heights, New York 10598 (electronic mail: sandrajb@us.ibm.com). Dr. Baylor is a manager and a research staff member at the Watson Research Center in Hawthorne, New York. She earned her B.S., M.S., and Ph.D. degrees in electrical engineering from Southern University (summa cum laude), Stanford University, and Rice University, respectively. She joined IBM at the Research Center in 1988. She has conducted research on the performance evaluation of cache coherence protocols in shared memory multiprocessors, parallel application workload characterization, parallel I/O design and evaluation, parallel file system design, and thin-client application framework analysis and development. She is currently the manager of the Java Server Performance (JASPER) research group. Her areas of interest include computer architecture, memory systems, parallel processing, performance evaluation, and Java performance.

Murthy Devarakonda   IBM Research Division, Thomas J. Watson Research Center, P.O. Box 704, Yorktown Heights, New York 10598 (electronic mail: mdev@us.ibm.com). Dr. Devarakonda is a senior manager in IBM Research currently managing groups working in the areas of pervasive and personal computing systems. Earlier, as the manager of the Java server performance project, he developed the strategy for it and led the definition of several Java server benchmarks. Prior to this work, he built a fully recoverable, cluster file system called Calypso, managed the eNetwork Dispatcher research, and led research in Java object frameworks for thin-client applications (TCAF) and script-based mobile agents (NetScript). TCAF and NetScript are available from IBM alphaWorks™. He received a Ph.D. in computer science from the University of Illinois at Urbana-Champaign. He was the program chair for the USENIX COOTS Conference in 1999, and he is the object-oriented systems area editor for IEEE Concurrency.

Stephen J. Fink   IBM Research Division, Thomas J. Watson Research Center, P.O. Box 704, Yorktown Heights, New York 10598 (electronic mail: sjfink@us.ibm.com). Dr. Fink is a research staff member at the Thomas J. Watson Research Center. He received the B.S. degree from Duke University, Durham, North Carolina, in 1992, and the M.S. and Ph.D. degrees from the University of California, San Diego, in 1994 and 1998, respectively. His research interests include dynamic compilation, run-time systems, object-oriented programming, and parallel scientific computation.

Eugene Gluzberg   IBM Research Division, Thomas J. Watson Research Center, P.O. Box 704, Yorktown Heights, New York 10598 (electronic mail: gluzberg@us.ibm.com). Mr. Gluzberg received his M.S. and B.S. degrees in computer science from Polytechnic University. He has been with IBM Research since June 1998, working on the jMocha microbenchmark suite along with other Java-related projects in the Java Server Performance group.

Michael Kalantar   IBM Research Division, Thomas J. Watson Research Center, P.O. Box 704, Yorktown Heights, New York 10598 (electronic mail: kalantar@us.ibm.com). Dr. Kalantar is a visiting scientist at IBM Research. His current interests are performance studies of Java and computer communications. He received his doctorate at Cornell University in 1995 and spent two years teaching computer science in China.

Prakash Muttineni   EC Cubed, Inc., 15 River Road, Suite 310, Wilton, Connecticut 06987. Dr. Muttineni received both the B.Tech (civil engineering) and M.Tech (computer science) degrees from the Indian Institute of Technology in Madras, India, in 1984 and 1986, respectively. He received a Ph.D. (computer science) degree from the Indian Institute of Sciences in Bangalore, India, in 1996. He was a faculty member at the Regional Engineering College in Warangal, India, for several years. During the last two years, he was at the IBM Thomas J. Watson Research Center with the Java Server Performance team.

Eric Barsness   IBM Software Group, 3605 Highway 52 North, Rochester, Minnesota 55901 (electronic mail: ericbar@us.ibm.com). Mr. Barsness is a software engineer with the IBM Server Group in Rochester. He joined IBM in 1993 and currently works in the AS/400 systems performance area. His primary responsibility since 1996 has been AS/400 Java performance analysis. Mr. Barsness holds a B.S. in computer science from Iowa State University.

Rajiv Arora   IBM Network Computing Software Division, 11400 Burnet Road, Austin, Texas 78758 (electronic mail: rarora@us. ibm.com). Dr. Arora is a performance engineer whose current interest is the performance of the Java language on the server. He is working on core performance of the IBM Jvms on the Intel platform. He also represents IBM on the SPEC server-side Java benchmark working group. Prior to his Java work, he worked on Web server performance and the performance of TCP/IP on AIX, the IBM microkernel, and OS/2. Dr. Arora joined IBM in 1992. He holds M.S. and Ph.D. degrees in electrical engineering from the University of Rochester in the area of network protocols.

Robert Dimpsey   IBM Network Computing Software Division, 11400 Burnet Road, Austin, Texas 78758 (electronic mail: dimpsey@us.ibm.com). Dr. Dimpsey received his Ph.D. degree in 1992 from the University of Illinois where he studied performance measurement, modeling, and analysis of large shared memory multiprocessors. In 1992 he joined IBM to work on symmetric multiprocessing performance of the AIX operating system. In 1994 he began work on the IBM cross-operating system microkernel project. This was followed by work on kernel-level multiprocessor performance for WARPSMP and scalable, journaled file systems. Currently, he is working on server-focused, core Jvm performance for IBM Jvms on Intel-based platforms.
