Outstanding Innovation Award for work on Intersystem Channel products.
Cyril A. Price IBM System/390 Division,
522 South Road, Poughkeepsie, New York 12601
(PRICECA at IBMUSM10, priceca@us.ibm.com). Dr. Price is
Program Manager of CEC Subsystems in the S/390 Hardware Development
Product Line Management organization, currently working on the
development of the IBM S/390 CMOS servers. He graduated from Pratt
Institute with a B.E.E. degree in 1969, and received his M.S.E.E. and
D.E.E. degrees from Syracuse University in 1977 and 1986, respectively.
He joined IBM in 1969 as a circuit/chip designer and then served two
years as a U.S. Army Signal Corps officer. In 1978 he was named
manager of Circuit and Subsystem Design. From 1979 to 1981, he was
Manager of LSI Design and Manager of Exploratory Circuits. From 1981 to
1992, he held several management positions, including Advanced Design
Manager responsible for CMOS chip development, and IBM Kingston
Technology Manager responsible for technology support of IBM Enterprise
System/9000 Type 9121 air-cooled processors. Dr. Price has received
an IBM Outstanding Technical Achievement Award and an IBM Invention
Achievement Award for patents and technical disclosures. In 1992 he was
named Manager of Advanced Development, responsible for the initial
research and development and successful product introduction of the IBM
S/390 G4 microprocessor.
Chitta L. Rao IBM System/390 Division,
522 South Road, Poughkeepsie, New York
12601 (clrao@vnet.ibm.com). Dr. Rao is with the S/390 platform
management area, working on Parallel Sysplex performance. He received
an M.S. in electrical engineering from McGill University, Montreal,
Canada, and a Ph.D. in theoretical nuclear physics from the
University of Tennessee. Prior to joining IBM, Dr. Rao was engaged in
research in nuclear physics, digital filters, and image processing. He
joined IBM to work on large-system scientific and engineering processor
design and development. Since 1991 he has been involved in the
performance analysis of coupling facility design alternatives and
Parallel Sysplex system performance.
Steven J. Repka IBM System/390 Division,
522 South Road, Poughkeepsie, New York 12601
(srepka@vnet.ibm.com). Mr. Repka is a Senior Engineer working in
the S/390 System Design group. He received a B.S. in computer
engineering from Case Western Reserve University in 1978, joining IBM
at the Poughkeepsie Laboratory that same year. He has held a
variety of technical and managerial positions in processor design,
engineering systems test, and field product support. Mr. Repka has
worked on the development of S/390 large systems, including the 3090
and ES/9000 processor families, and, most recently, the S/390 G4
server.
