Adapting Computer Arithmetic Structures to Sustainable Supercomputing in Low-Power, Majority-Logic Nanotechnologies.

Petascale supercomputers are already pushing power boundaries that can be supplied or dissipated cost-effectively; greater challenges await us in the era of exascale machines. We are thus motivated to study methods of reducing the energy cost of arithmetic operations, which can be substantial in numerically intensive applications. Additionally, being both a widely-used operation in itself and an i...
