WattProf: A Flexible Platform for Fine-Grained HPC Power Profiling
2015
The ability to monitor power and energy accurately and efficiently is becoming increasingly important in all areas of computing. In this paper, we introduce WattProf, a portable and flexible power monitoring platform that allows for fine-grained monitoring of power and energy consumption in various hardware components of HPC clusters. The WattProf system consist of a programmable monitoring PCIe expansion card, sensors for individual system components, host runtime system, and a high-level application programming interface. We demonstrate the use of WattProf on two benchmarks.
