Energymon
Energymon is an open-source software library and toolset designed for monitoring and profiling energy consumption in computing systems, particularly for high-performance computing (HPC) and embedded applications. It provides a portable, cross-platform API to measure power usage across various hardware components like CPUs, GPUs, and memory, enabling developers to optimize energy efficiency. The tool supports multiple backends for different hardware sensors and integrates with performance analysis frameworks.
Developers should learn Energymon when working on energy-aware applications, such as in HPC clusters, data centers, or IoT devices, where reducing power consumption is critical for cost savings and environmental sustainability. It is especially useful for profiling energy usage during software development to identify inefficiencies, benchmark energy performance, and comply with green computing standards. Use cases include optimizing scientific simulations, edge computing deployments, and battery-powered embedded systems.
