I have done my Master's work with the XCore (xmos.com), which is a direct descendant of the Transputer. It's programmed in an C-with-CSP-constructs called XC. I found it very easy to write XC correctly. I think that the CSP/transputer idea is really the best way for most parallel programming to happen. MPI and pthreads allow more flexibility, but in most (say, 80%) of cases, that's not needed for your application.
