  abstract= "A multi-processor implementation of occam2.1 for
     interconnected DEC Alpha processors has been derived from
     the Kent Retargetable occam Compiler. Each Alpha processor
     is supported over a PCI bus by a T425 transputer, whose
     links complete the communications fabric. This paper reports
     on the software mechanisms for supporting these platforms
     from occam so that they appear just like any transputer
     system -- a collection of processing nodes connected by
     channels placed on links. Advantage was taken of a
     proprietary multi-threading kernel, supplied as part of 3L
     Parallel C/AXP, to support parallel inter-node
     communication. occam multi- processing is supported by the
     KRoC kernel running within one of the 3L threads. The
     performance of generated code and networked systems has been
     benchmarked, with particular care being taken to measure the
     interaction overheads between the Alpha and its
     communication fabric. An image analysis program was also
     used in the benchmarking as an example of a real
     multi-processor application."
