摘要

•Analyzing OpenMP runtime configurations’ impact on a power constrained system.•Careful configuration selection can improve execution time and energy consumption.•Parallel region level performance & energy improvement up to 67% & 72% respectively.•Application level performance & energy improvement up to 26% and 38% respectively.•Best execution time does not always result in best energy consumption.
