This paper describes recent enhancements to the Common Lisp system that BBN is developing for its Butterfly multiprocessor. The BBN Butterfly is a shared memory multiprocessor that contains up to 256 processor nodes. The system provides a shared heap, parallel garbage collector, and window based I/Q system. The "future" construct is used to specify parallelism.
