Using X11 Windows To Provide Shared Task Memory in Distributed Computer Systems

Abstract

An X11 based shared memory system, permitting the implementation of a distributed water network monitoring and control software suite, is described in this paper. The application source code is in FORTRAN and accesses shared memory via a C library module requiring no other support packages. X11 based distributed mutual exclusion algorithms, based on the unconventional use of Lamport's bakery algorithm, are evaluated. The system is compared with other methods of providing distributed shared memory
