Parallelization has been used to maintain a reasonable balance between energy consumption and performance in computing platforms especially in modern multi- and many-core systems. This paper studies the interplay between performance and energy, and their relationships with parallelization scaling in the context of the reliable operating region, focusing on the effectiveness of parallelization scaling in throughput-power tradeoffs. Theoretical and experimental explorations show that a meaningful cross-platform analysis of this interplay can be achieved using the proposed method of bi-normalization of the ROR. The concept of this interplay is captured in an online tool for finding optimal operating points.
