%X Progress has been made in providing a reasonable distributed
implementation of the occam language. Primarily, this has
involved the development of a routing kernel with a latent
channel connection retaining occam syntax. Channel semantics
are maintained by a message acknowledgement scheme and
unrestricted message lengths. This provides the user with
the potential for fully connected process communication
without restrictions on node valencies or explicit PLACEment
of any hard links.In addition the user program has been
severed from any dependency on the topology by allowing
multiple configuration level PROCESSORS to map onto a single
transputer. Thus the user code can be run on any network
which has been configured for the virtual channel
router.Further development of the system has allowed us to
implement the dynamic primitives that will be required by a
compiler for distributed full occam. These include dynamic
channel creation, remote procedure calls and facilities for
moving channel ends.
