Integration of automated and user-level tools toward efficient parallel objects allocation

Automated allocation tools do not achieve the same efficiency for all kinds of applications. A parallel programming environment should integrate high-level tools to permits users to easily adapt the behaviour of the automated allocation tools to the peculiar application needs. The paper faces this problem and presents a set of high-level directives to specify the allocation needs of the components of parallel applications based on the active object model. The allocation directives can drive the allocation decisions of the automated tools, by tuning their general-purpose behaviour to the peculiar application needs.
