Abstract Over the past years power and energy consumption have become the driving metrics for the design of computing hardware including multicore CPUs and accelerators. Power-conscious designs also dominate large supercomputing installations as well as large industrial complexes devoted to cloud computing and big data analytics. With serious financial and environmental consequences, large scale computing community has to now cope with careful re-engineering of software to fit demanding power levels and tight energy envelopes.

  Abstract. Over the past few years, the energy consumption and power constraints have started playing a major role in the use of HPC systems. They have also become one of the major design constraints for building the future hardware for the hundred Peta- and the Exa-flop/s supercomputers. This talk will track some of the technological trends, that were the effect of this transition and are likely to continue into the future. Adapting to this dramatic shift in hardware constraints is believed to be one of the major issues for porting the essential applications of computational science and have them run efficiently on the upcoming systems. The examples in the talk will provide examples of software solution for better utilization of energy and adaptation of the power constraints.
