Energy conservation in heterogeneous server clusters

Taliver Heath, Bruno Diniz, Enrique V. Carrera, Wagner Meira Jr., Ricardo Bianchini
2005 Proceedings of the tenth ACM SIGPLAN symposium on Principles and practice of parallel programming - PPoPP '05  
To concretely illustrate this process, we design a cooperative Web server for a heterogeneous cluster that uses modeling and optimization to minimize the energy consumed per request.  ...  However, real-life clusters are almost invariably heterogeneous in terms of the performance, capacity, and power consumption of their hardware components.  ...  Comparing Server Systems The reason for the inefficient behavior of Adaptive is that it treats a heterogeneous system as if it were homogeneous.  ...
