  abstract= "The Cell Broadband Engine has a unique non-heterogeneous
     archi- tecture, consisting of an on-chip network of one
     general purpose PowerPC pro- cessor (the PPU), and eight
     dedicated vector processing units (the SPUs). These
     processors are interconnected by a high speed ring bus,
     enabling the use of different logical network topologies.
     When programming the Cell Broadband Engine using languages
     such as C, a developer is faced with a number of
     chal- lenges. For instance, parallel execution and
     synchronisation between proces- sors, as well as
     concurrency on individual processors, must be explicitly,
     and carefully, managed. It is our belief that languages
     explicitly supporting concur- rency are able to offer much
     better abstractions for programming architectures such as
     the Cell Broadband Engine. Support for running occam-
     programs on the Cell Broadband Engine has existed in the
     Transterpreter for some time. This support has however
     not featured efficient inter-processor communication and
     barrier synchronisation, or automatic deadlock detection.
     We discuss some of the changes required to the occam-
     scheduler to support these features on the Cell Broadband
     Engine. The underlying on-chip communication and
     synchronisation mechanisms are explored in the development
     of these new scheduling algorithms. Benchmarks of the
     communications performance are provided, as well as a
     discussion of how to use the occam- language to distribute
     a program onto a Cell Broadband Engine\&\#8217;s
     processors. The Transterpreter runtime, which already has
     support for the Cell Broadband Engine, is used as the
     platform for these experiments. The Transterpreter can be
     found at www.transterpreter.org."
