Some time ago, I created presentation for my university connected with Distributed Inter-Process Communication.
It is a piece of software dedicated for Linux OS, created by Kamran Karimi, which allows to distribute software operations inside computer cluster. In addition, we can test it on a single machine during development process and run on a several machines in the production phase.
I tested this solution on Ubuntu Linux. Short description of this system is presented below.
DIPC (Distributd Inter-Process Communication) is a software-only solution for distributed data exchange on a network on Linux computers. It operates at the kernel level, and allows the programmer to use System V semaphores, message queues, and shared memory segments over the network with minimal change at the source code level.
