Does any know of a C* (that is, Connection Machine C) language simulator in the public domain? It doesn't have to accept absolute legal C* syntax; just some reasonable approximation. Of course, it would be compiled for a serial host. My best guess is that such a beast would be written in C++ using classes for domains and overloading the heck out of operators. Anyone seen or written such a thing? Any insights on how one would do it?

When you write a C* program you make calls to routines that call Paris instructions during execution. The only routines that actually get executed on the CM are the Paris (Parallel Instruction Set) instructions; other non-paris routines get executed on the front end. To get a working program you have to include the -lparis library during compile time. The compiler then does the appropriate compilation taking care of the Paris instructions. If you specify the option -sim to the compiler it will compile the C* program so that when invoked it will run on the front end only; Paris instructions are simulated. So the simulator is actually a part of the compiler in this case. I do not know of any public domain C* compiler (complete with simulator). There are also simulators for the *Lisp programming environment but I do not know of any that are public domain. There is a simulator based on Koyoto Common Lisp that runs on a Sun3 workstation (basically a package that gets included in the default world) and a simulator for the VAX front end that has several different worlds depending on what you want included in the world (one of these worlds being a simulator). >My best guess is that such a beast would be written in C++ using classes >for domains and overloading the heck out of operators. It turns out that the TMC C* compiler is written in lisp and is extremely slow in both compilation and execution. Last I heard TMC is rewriting the compiler to be extremely fast and the new compiler should be out next year(89) but don't quote me on that ;-). I hope this answers some of your questions. I shall post some mail to some of the more productive mail-lists for the CM users asking if there are any public domain versions of the simulators but I seriously doubt there will be. You may be able to get a simulator, at least the *Lisp simulator, from TMC but I doubt that is what you are looking for.
