Energy efficiency is a key design concern in contemporary processor and system design, in the embedded domain as well as in the enterprise domain. The focus on energy efficiency has led to a number of power benchmarking methods recently. For example, EEMBC released EnergyBench and SPEC released SPECpower to quantify a system's energy efficiency; also(More)
Simulating contemporary computer systems is a challenging endeavor, especially when it comes to simulating high-end setups involving multiple servers. The simulation environment needs to run complete software stacks, including operating systems, middleware, and application software, and it needs to simulate network and disk activity next to CPU performance.(More)
The amount of data produced on the internet is growing rapidly. Along with data explosion comes the trend towards more and more diverse data, including rich media such as audio and video. Data explosion and diversity leads to the emergence of data-centric workloads to manipulate, manage and analyze the vast amounts of data. These data-centric workloads are(More)
Designing data centers for Web 2.0 social networking applications is a major challenge because of the large number of users, the large scale of the data centers, the distributed application base, and the cost sensitivity of a data center facility. Optimizing the data center for performance per dollar is far from trivial. In this paper, we present a case(More)
