He joined IBM in 1984. Since 1990, he has been working on research and development of compilers, including HPF (high-performance FORTRAN) and Java JIT compilers.
Sally Howard
IBM Hursley Development Laboratory, Java Technology Centre, Hursley Park, Winchester, Hants S021 2JN (electronic mail: sally_howard@uk.ibmmail.com).
Ms. Howard is the lead developer of the porting team for the IBM Developer Kit for OS/390, Java Technology Edition, in the Java Technology Center at Hursley Park. She has worked on this project since its inception in 1996.
Michael F. Oliver
IBM S/390 Division, 2455 South Road, Poughkeepsie, New York 12601 (electronic mail: mfoliver@vnet.ibm.com).
Mr. Oliver, program director for the IBM Developer Kit for OS/390, Java Technology Edition, has worked for IBM for 34 years in various technical, planning, and managerial positions in software development. He was recently the program manager responsible for the strategy, planning, and delivery of object technology for OS/390. His current responsibilities include complete product management of DK for OS/390, including planning, coordination of development, and delivery of Java products and technologies for OS/390 from IBM development laboratories in England, Israel, Japan, Toronto, and the United States. He is a recipient of several IBM excellence awards for management and technical achievement. He received a B.S. degree in electrical engineering in 1965 from Worcester Polytechnic Institute, Worcester, Massachusetts.
Frank Samuel
IBM Server Group, P.O. Box 6, Endicott, New York 13903 (electronic mail: samuelfs@us.ibm.com).
Mr. Samuel joined the former IBM Systems Products Division in 1973. He worked on hardware performance and developed microcode for the 4331, 4361, and 9370 processors for 18 years, before beginning performance work and technical ownership for MUMPS/VM (Massachusetts General Hospital Utility Multiprogramming System/ Virtual Machine) in 1991. In 1994 he joined the OS/390 OpenEdition DCE (Distributed Computing Environment) development team. He has worked on performance for the IBM Developer Kit for OS/390, Java Technology Edition, since 1998.
Robert W. St. John
IBM S/390 Division, 2455 South Road, Poughkeepsie, New York 12601 (electronic mail: rstjohn@us.ibm.com).
Mr. St. John joined IBM in Poughkeepsie in 1982. After a number of years designing and developing MVS (multiple virtual storage, now OS/390) performance tools, he turned his attention to performance analysis. In 1990, he joined a group with the seemingly impossible mission of providing UNIX services under MVS. He worked through 1997 on design, development, and performance analysis of what is now called OS/390 UNIX System Services. In December of 1997, Mr. St. John began focusing on Java performance analysis. He now serves as the technical leader of a team of performance analysts working on the IBM Developer Kit for OS/390, Java Technology Edition.
