WoTUG - The place for concurrent processes

Paper Details

An environment for investigating the effectiveness of process migration strategies on transputer-based machines

Authors: Philips, Joe, Candlin, Rosemary


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.
