Evaluating Software and Systems with PowerTOP
{"Image DocumentName": "Evaluating Software and Systems with PowerTOP", "Image ImageDescription": "PowerTOP can be used to measure and improve performance of code as it is written. The measurement harness is implemented in Python. To begin, the developer identifies the target code for measurement, referred to as the code-under-test (CUT) Basic Operation of the Measurement Harness. Phase 1. Discover the maximum rate of execution of the CUT. Phase 2. Measure the power efficiency at the maximum execution rate. Phase 3. Measure the power efficiency as execution rate is scaled down from maximum. Two key parameters manipulated in Phase 3: - total fraction of sleep time during the experimental observational period. - duration of an individual sleep interval.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
