MPI Ruby is a Ruby binding of MPI. The primary goal in making this binding was to make the power of MPI available to Ruby users in a way that fits into the language's object oriented model. In order to do this, the buffer and datatype management necessary in the C, C++, and Fortran bindings have been removed. What this means is that MPI Ruby allows you to treat objects as messages. MPI Ruby also aims to be a complete binding to MPI, in that it offers access to nearly all functionality of MPI.
