Current compilers work has two dimensional model, i.e., all the optimization phases are targeted either towards reducing execution time or code size. My question is: Do we need to change this model and make it three dimensional by adding power axis in the search space? If yes, then we have to revisit all the phases and adjust them or come up with new cost models for these phases. I will be grateful if some one can point me to the latest efforts/projects with respect to power efficient compilation for high performance computing. Thanks
