2017 ACM Transactions on Architecture and Code Optimization (TACO)  
Acknowledgement This research has been supported by the UK Engineering and Physical Sciences Research Council (EP-SRC) through grant agreements EP/L000055/1 (ALEA), EP/L004232/1 (ENPOWER), EP/M01567X/1  ...  We demonstrated that ALEA achieves highly accurate energy estimates with worst-case errors under 2% for coarse-grained code blocks and 6% for fine-grained ones.  ...  Again, VPM can handle programs with fast changing power behavior better than CPM and produces accurate estimates. Limitations of ALEA ALEA is a tool for fine-grained energy profiling.  ...

FPowerTool: A Function-level Power Profiling Tool

Guang Wei, Depei Qian, Hailong Yang, Zhongzhi Luan, Lin Wang
2019 IEEE Access  
The energy consumed by code at the granularity of function is measured by sampling the energy usage hardware counters built in the CPU and the sampled value is associated to the corresponding code segments  ...  Two issues have been addressed: associating the power consumption data with the individual function code segments and reducing the overhead of power profiling.  ...  ALEA is a tool for measuring power and energy consumption at the granularity of basic blocks, using a probabilistic approach [14] , [15] .  ...

Power Capping: What Works, What Does Not

Pavlos Petoumenos, Lev Mukhanov, Zheng Wang, Hugh Leather, Dimitrios S. Nikolopoulos
2015 2015 IEEE 21st International Conference on Parallel and Distributed Systems (ICPADS)  
We systematically analyze the strengths and weaknesses of each mechanism, in terms of energy efficiency, overhead, and predictable behavior.  ...  The profiler operates in user space and provides fine-grain energy profiling at the granularity of basic blocks.  ...  We performed energy measurements using ALEA [22] , an in-house energy profiler based on statistical sampling of power consumption.  ...
