It uses Java Swing to give user the Graphical User Interface to represent a parallel processing simulation of war simulation. This java program files only represent the GUI part of the parallel processing simulation while the real work of simulation is being done by other program that is located in CSCI's server. However I was required to read, to understand, and to report back to my professor of what is parallel processing simulation all about [mostly the concept of federation]. I was asked to create the GUI part of parallel processing simulation.
