Abstract:
Increasing complexity of current and future systems poses a new challenge for software engineers. In a previous work we presented a light-weight runtime system for abstraction of heterogeneous parallel systems. This runtime system adapts an application to the current system state in order to improve the utilization of the available resources. For online evaluation of such adaptions, we propose a versatile instrumentation mechanism that can be used by the runtime system. We show that this technique introduces only minor overhead and we compare it to the Dyninst mechanism.
