||The EC-funded Adept project addresses the challenge of energy-efficient use of parallel technologies. We will present early results in measuring the power usage of parallel software and hardware, following three clear strands:
The BoF will consist of three short talks on each of the three strands, followed by a moderator-led discussion.
- Adept is developing benchmarks to help attribute power usage to specific components in a parallel application. We will present our advances in getting accurate and meaningful measurements (as well as the challenges faced), and discuss the value of the information that can be gained.
- To measure the power usage of parallel software to a high resolution, we need to either instrument the hardware or rely on vendor-exposed energy usage information. We will discuss our methodology, and compare accuracy and reliability of different measurement techniques.
- We will consider “performance vs. energy usage” metrics, which important in order to directly compare different types of software applications running on different hardware architectures, and to quantify the performance/energy trade-off.
