%X This paper describes an experimental system which can be
   used to study and compare the behaviour of different process
   migration strategies for occam programs running on
   transputer machines. The approach taken involves loading the
   code and data for every process onto every transputer.
   Processes can then be enabled and disabled to reflect the
   initial placement and subsequently to reflect process
   migrations. While simplifying the implementation process
   this means that the entire program must fit onto a single
   transputer. A statistics collection mechanism has also been
   implemented to enable intelligent migration decisions to be
   made. The system has been verified using a random migration
   strategy on several candidate programs.
