XMPSIM

XMPSIM is a CRAY X-MP simulator written by Steven Robbins of the University of Texas at San Antonio. XMPSIM runs only under DOS on 80x86 machines. It has some nice features, such as the ability to produce a Gantt chart showing pipeline timing. Besides, it's cool to be able to simulate a $12 million machine using free software on a cheap PC.
