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.
