The paper presents the Abstract Configuration Language (ACL) implemented within the Parallel Objects object-oriented parallel programming environment. ACL defines a set of directives that allow users to specify the allocation needs of his/her application components without being aware of the architectural details. ACL directives drive the allocation decisions of the run-time support, by adapting its general-purpose behaviour to follow applications particular allocation needs. The effectiveness of the ACL approach in increasing the performances of parallel applications is confirmed by a testbed application.
