%T The Kent Retargettable occam Compiler %A David C. Wood, Peter H. Welch %E Brian C. O\[rs]Neill %B Proceedings of WoTUG\-19: Parallel Processing Developments %X A generic approach to targeting occam to non\-transputer architectures is described. The principle is to build a register\-level emulation of the major design elements of the transputer, using native registers of the target hardware, and reuse the standard occam toolset compiler with as little alteration as possible. The porting effort thus reduces to an architectural mapping rather than involvement in the compiler and code\-generator. An immediate payoff comes from reuse of a well\-developed and sophisticated compiler. An important scientific question, with relevance to efficient and portable parallel computing, is whether the crucial benefits of transputer architecture (such as the very low overheads for the management of processes and events) can be transferred through such emulation. We report some initial results for SPARC\-based targets.
