CL-MPI is a portable, CFFI-based Common Lisp binding for MPI. CL-MPI enables parallel programming in Common Lisp using a message-passing model on either a cluster of machines, or a single multicore machine. CL-MPI has been successfully tested with SBCL (both 32/64-bit) and CMUCL, with MPICH1.2 and MPICH2 1.0.8. CL-MPI can also be used to provide "true" multiprocessing for some Common Lisp implementations which don't have native threading capabilities.
Created attachment 203380 [details] development-untested-ebuild I have not tested this ebuild but at least it gets some of the boilerplate out of the way. Please not that the install process is probably not as straight forward as one would hope, please check last section of the README.
Created attachment 203381 [details] fixed-digest-problem Sorry about the last ebuild. At least this one digests properly. Still does not work though...
