CL-MPI enables parallel programming in Common Lisp using a message-passing model on either a distributed cluster of machines, or a single multicore machine. It has been successfully tested with SBCL, CCL and ECL, and fot the MPI implementations MPICH, OpenMPI and IntelMPI.
CL-MPI can also be used to provide "true" multiprocessing for some Common Lisp implementations which have no native threading capabilities.
