Multiprocessor Common Lisp on TOP-1

TOP-1 Common Lisp is an implementation of Common Lisp on TOP-1, a shared-memory multiprocessor workstation developed at IBM Tokyo Research Laboratory. The authors describe TOP-1 Common Lisp's extensions to the Common Lisp language: the ability to create multiple processes and the future construct. They analyze the changes to the scope and extent of variables induced by introduction of concurrency. They discuss the implementation of a Lisp process, the problem caused by co-existence of the future construct and the multiple value facility, and the design of a real-time, multiprocessor garbage collector. The authors present some results of the experiments conducted with TOP-1 Common Lisp.<<ETX>>
