ACK is a compiler suite (perhaps analogous to gcc). Kevin Jordan maintains a fork of ACK that generates code for the Cray X-MP, a member of a family of famous vector supercomputers. As much of the original software for the Cray family has been lost, this ACK fork may be the only remaining way to program a Cray X-MP (running COS) in a high level language. https://en.m.wikipedia.org/wiki/Amsterdam_Compiler_Kit https://en.m.wikipedia.org/wiki/Amsterdam_Compiler_Kit https://en.m.wikipedia.org/wiki/Cray_X-MP https://en.m.wikipedia.org/wiki/Cray_X-MP You may be able to run generated executables in an emulator or online. http://www.nostalgiccomputing.org/ http://www.nostalgiccomputing.org/ https://github.com/andrastantos/cray-sim https://github.com/andrastantos/cray-sim
