Investigating power efficiency of mergesort [PDF]

The Journal of Supercomputing, 2019
Excessive power consumption emerged as a major obstacle to achieving exascale performance in next-generation supercomputers, creating a need to explore new ways to reduce those requirements. In this study, we present a comprehensive empirical investigation of a power advantage anticipated in the mergesort method based on identifying a feature expected ...

5. On the Efficient Powers of Parturition [PDF]

Proceedings of the Royal Society of Edinburgh, 1872
There can be no doubt that, among the numerous matters at present occupying the attention of obstetricians, none is more important than the subject of this paper. So evident is the correctness of this statement that one cannot but wonder why attempts to arrive at the truth have been, so far as we know, delayed till the present day.

Power-Efficient DRAM Speculation [PDF]

2008 IEEE 14th International Symposium on High Performance Computer Architecture, 2008
Power-efficient DRAM Speculation (PEDS) is a power optimization targeted at broadcast-based shared-memory multiprocessor systems that speculatively access DRAM in parallel with the broadcast snoop. Although speculatively accessing DRAM has the potential performance advantage of overlapping DRAM latency with the snoop, it wastes power for memory ...
