Abstract

This paper presents an empirical investigation of policy-based self-management techniques for
parallel applications executing in loosely-coupled environments. The dynamic and heterogeneous
nature of these environments is discussed and the special considerations for parallel applications
are identified. An adaptive strategy for the run-time deployment of tasks of parallel applications
is presented. The strategy is based on embedding numerous policies which are informed by
contextual and environmental inputs. The policies govern various aspects of behaviour, enhancing
flexibility so that the goals of efficiency and performance are achieved despite high levels of
environmental variability. A prototype self-managing parallel application is used as a vehicle to
explore the feasibility and benefits of the strategy. In particular, several aspects of stability are
investigated. The implementation and behaviour of three policies are discussed and sample results
examined.
