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

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

XDSM -- an X11 based Virtual Distributed Shared Memory System

... this paper. The system is based on the use of modular library and language specific interfaces, to access the underlying X11 communications platform supporting distributed shared memory (DSM). The system uses a server client relationship, with local computer node task managers, and uses the DSM for communication, configuration and coordination. An X11 based distributed mutual exclusion algorithm, based on the unconventional use of Lamport's bakery algorithm, is illustrated
