  • Profession   :Computer Scientist




             Peter G. Gyarmati  is a software engineer and computer scientist.He is best-known for the development of  OS/360+HASP for the System/360.Later developed  the OS/VS for the System/370, for  resource allocation system.He introduced here the adaptive allocation strategy based on his earlier engineering works.

Born in Budapest,Hungary and there he received BSc(ENG)from Budapesti Muszaki Egyetem and MSc from Mancester University,England in 1972,and he received a PhD in Applied Computer Science from ELTE in 1981.


        In Manchester University he joined for research to IBM from 1972 until 1981, working in Poughkeepsie, Yorktown, New York, and the Delft University, Holland. In his PhD work “Adaptive Controls in Operating System”, he proposed the so called ADIOS solution, extension to the System/370 family, with the OS/VS2 software.

He actively studied about the ALOHA type networks and suggested the solutions for the collision problem and gave a proof for the radio communication channel capacity. It is essential for the Ethernet(ieCSMA/CD protocol).         




He then developed the PC and  micro Computing, where he introduced a fore runner of the portable computer, a portable data collector machine, called MOBI-X, then MOBI-2000. He also designed, created and patented the portable OS.Later he worked with networking reliability, security, in Vienna  and Stuttgart and also in Budapest for BSB, TCC and worked in Stanford University, Palo Alto, U.S. as a guest professor, and as emeritus returned to Szentendre, where he lives now. He is member of the PhD body of the HAS (Hungarian Academy of Sciences) and of the Bolyai Society of Mathematics.
