Energy Aware Runtime (EAR)

Performance Tools

Energy Aware Runtime (EAR) offers an automatic, dynamic and transparent solution to energy aware users with minimal performance overhead. EAR  dynamically detects the iterative pattern of an HPC application while it’s running (through Dynamic Pattern Detection - DPD). Once the application structure is detected, it monitors the application and computes the application signature (CPI,GBs,Time and Power) and selects the optimal node frequency based on user-guided energy policies to quantify the trade-off between power, performance and energy. These policies use performance models that receive as input the application signature, computed at runtime,  and the architecture characterization done at installation time.
