More than 35 years experience in the design, planning, and analysis of
complex computer systems, with emphasis on the development, evaluation,
and coordination of solutions that cross subsystem boundaries.
Extensive systems experience including MVS, AIX, VM, DOS and Windows,
DCE (the OSF "Distributed Computing Environment"),
OS/2, C language, REXX, HTML,
and systems architecture. Avid PC user and
programmer since 1987. Demonstrated management and technical leadership
abilities. Innovative and creative problem solver. Effective
communicator, able to explain complex concepts in understandable terms.
Generalist with a wide range of experience and ability to learn new
I am seeking part time/contract work in areas such as (but not limited to):
- Web site creation (links on home page).
- Systems Architecture and design
- OS/2 assistance
- Rexx programming
I am located in the Finger Lakes area of Central New York State.
Accomplishments and Work History
1993 - present: Web Site Construction, Consultant and Teacher
1990-93 Senior Engineer; IBM Enterprise Systems, Kingston.
System Design and Architecture department, AIX/ESA development.
- Defined the Distributed Computing Environment (DCE) architecture
and plan for the AIX/ESA operating system from initial stages
until well into the development phase.
- Acted as technical owner of AIX/ESA planning manual.
Interacted with the developers of most system components and
reduced much technical detail to a summary form usable by
technically unsophisticated users.
- Evaluated (as a member of a strategy design team) alternative
cluster coupling designs with emphasis on cluster-wide access
to data and files. Also analyzed compute-intensive
applications for parallelization to determine data transfer
- Invented (with co-inventors) an improved MP Queue management
instruction with deadlock avoidance. A patent application was filed.
1979-89 Senior Engineer, IBM Poughkeepsie.
3090 (XA, ESA) system design and architecture.
- Initiated design, architecture, and implementation plans for
the ESA Sysplex Timer (ETR). Worked with engineers from
several machine groups and functions as well as programmers,
product planners, and marketing specialists. Reviewed the
design with selected customers and sold the concept to
management. Co-authored IBM Journal
of Research & Development article describing this product.
- Developed high level system design for retrofit of Access
(a key component of IBM's ESA Architecture) to a processor
design that was well under way; this succeeded because of
careful allocation of function between elements of the
processor. Contributed to final definition of the
architecture. This effort enabled IBM to announce, test, and
deliver this function on an ambitious schedule. I received
an IBM major achievement award for this work.
- Performed initial design studies and cryptographic analysis,
developed high level
system design, and participated in the architectural
definition for the IBM Integrated Cryptographic Facility.
Worked with a major customer to understand their
requirements. Developed, in conjunction with a vendor, the
specifications for a critical electromechanical component.
The results of this effort, in addition to the product,
included 5 patents.
- Made major contributions to the IBM Vector architecture
enabled IBM to be a major contender in the high end
1962-79 IBM Poughkeepsie
Engineering including System/360 and System/370.
- Accomplishments included development of system microcode and
development tools, studies in telephony and satellite
communications, and engineering management.
Various assignments at several companies in
computer hardware and software design and development.
- Designed and wrote major systems programs
including compiler sections and simulators in varying
languages for different computer systems).
- PhD. requirements (except dissertation) completed: Harvard University.
- A. M. Harvard University 1957 (Applied Mathematics -
Computer Science program)
- A. B. (cum laude) Harvard College 1954 (Mathematics)
Patents, Publications, and Awards
- Eight patents issued or filed
- Co-Author of IBM Journal of Research and Development article [v 36 #4; July
1992] "Coordination of time-of-day clocks among multiple systems"
- Three IBM Invention Achievement and two IBM Outstanding Technical
- 2001 - Received the Ruth Polson Community Service Award
Finger Lakes Library System for
volunteer work in assisting several member libraries by developing and
running programs to convert patron database records from one automation system
