PATMOS has a history of 25 years and it is one of the first conferences world-wide to focus on low power. PATMOS 2015 is co-located with VARI 2015 and SBCCI 2015 in Salvador, Brazil. The traditional scope of the PATMOS conference series has mainly been about and around the design of circuits and architectures optimized for highest performance at lowest power consumption. But meanwhile, power-efficiency has become extremely important for many more areas spreading far beyond this traditional R&D niche. Energy-efficient ICT (Information and Communication Technology) infrastructures are a key issue of local and global economies. Some predict that until the year 2030, if current trends continue, the electricity consumption caused by the Internet to grow by up to 30 times. Energy prices will grow substantially. The next generation of oil and gas seismic simulations, for instance, will require orders of magnitude more computational power. Already during the past 11 years the price of crude oil increased by a factor of 9 with significantly increasing tendency in the future. The strong increase of wireless communication and the growth of cloud computing will further contribute to this trend. A future peta- or exa-flop supercomputer would need its own power plant if the gap between computation and power consumption could not be resolved: It is the intention of PATMOS 2015 to think beyond current solutions such that the very wide gap between computation and the massive energy consumption for ICT infrastructures can be closed.
