We are interested in languages that provide powerful abstractions for concurrency and parallelism that execute everywhere, efficiently. Currently, the existing runtime environments for the occam-π programming language provide either one of these features (portability) or some semblance of the other (performance). We believe that both can be achieved through the careful generation of C from occam-π, and demonstrate that this is possible using the Transterpreter, a portable interpreter for occam-π, as our starting point.
