Description

PowerSensor is a tool that measures the instantaneous power consumption of PCIe cards and SoC development boards like GPUs, Xeon Phis, FPGAs, DSPs, and network cards, at sub-millisecond time scale. It consists of a commodity microcontroller, commodity current sensors, and (for PCIe devices) a PCIe riser card. The microcontroller reports measurements to the host via USB. A small host library allows an application to determine its own energy efficiency. The high time resolution provides much better insight into energy usage than low-resolution built-in power meters (if available at all), as PowerSensor enables analysis of individual compute kernels.
