39th CREST Open Workshop
Measuring, Testing and Optimising Computational Energy Consumption
Date: 23 – 24 February 2015
Overview:
Estimates for the amount of global energy consumed by computation may very, but no commentator doubts its increase, with serious environmental implications. Users are also frustrated, all too aware of the computational limitations of inadequate battery life. Indeed, the largest component in many mobile devices is the battery. However, despite these pressing environmental and user needs, there remains a lack of work on computational energy testing and optimisation. The 39th CREST Open Workshop (COW) workshop will bring together those working on testing and optimisation with those working on computational energy measurement and its applications to investigate and develop computational energy testing and optimisation research and practice. Funding for the workshop is provided by the EPSRC projects GISMO (http://www0.cs.ucl.ac.uk/staff/W.Langdon/gismo/) and DAASE (http://daase.cs.ucl.ac.uk).
