We describe the design and early functionality of the Active Harmony global resource management system. Harmony is an infrastructure designed to efficiently execute parallel applications in large scale, dynamic environments. Harmony differs from other projects with similar goals in that the system automatically adapts ongoing computations to changing conditions through online reconfiguration. This reconfiguration can consist of system directed migration of work at several different levels, or automatic application adaptation through the use of tuning options exported by Harmony aware applications. We describe early experience with work migration at the level of procedures, processes and lightweight threads
