CrayCore is a CRAY YMP-EL Emulator. Currently, CrayCore executes instructions one at a time, through a command line interface. Future plans are to slowly add features until CrayCore is fully able to run Unicos. CrayCore version .3 has been released, in two packages, a source.zip, and a win32 binary. New features include light memory support, vector support, and many more opcodes. Be sure to check OpcodesTwo.txt, included with both packages for status on which instructions are implemented, and how to use them.
