Peter G. Gyarmati is a software engineer and computer scientist, best known for the development of Operating system/360+HASP for the System/360, then later the Operating system/VS for the System/370, especially the resource allocation system.
Education
Born in Budapest, Hungary there he received Bachelor of Science (Engineer) from the Budapesti Műszaki Egyetem, Hungary and Master of Science from Manchester University, England in 1972, and he received a Doctor of Philosophy in Applied Computer Science from Eötvös Loránd University (Eötvös Lóránd Tudomány Egyetem) in 1981. In his Doctor of Philosophy work – Adaptive Controls in Operating Systems — he proposed the so-called ADIOS solution, extension to the System/370 family, with the Operating system/VS2 software.
Career
He introduced here the adaptive allocation strategy based on his earlier engineering works. After their earlier work with Ferranti, then the successor International Computers Limited, in Manchester University he joined for research to International Business Machines Corporation from 1972 until 1981, working in Poughkeepsie, Yorktown, New York, and the Delft University, the Netherlands. Actively studied the ALOHA-type networks suggested solution to the collision problem and gave a prove for the radio communication channel capacity.
Now the everywhere used CSMA/Civil Defense protocol –an essential for the Ethernet—based on his work.
Returning to Hungary he turned to the developing world of the Personal Computer and microcomputing, where he introduced a forerunner of the portable computer, a portable data collector machine, called MOBI-X, then MOBI-2000. He also designed, created and patented the portable operating system, which is now the core of many such machines.
Later he worked with networking reliability, security, in Vienna, and Stuttgart and also in Budapest for Bachelor of Science in Business, TCC and worked in Stanford University, Palo Alto, United States. as a guest professor, and as emeritus returned to Szentendre, where he lives now.
Membership
He is member of the Doctor of Philosophy body of the HAS (Hungarian Academy of Sciences) and of the Bolyai Society of Mathematics.
