Disruptive changes in high-performance computing hardware, where data motion is the dominant cost, present us with an opportunity to reshape how numbers are stored and moved in computing. We are developing methods, tools, and expertise to facilitate the use of mixed and dynamically adaptive precision numbers, allowing us to store and move the minimum number of bits required to perform a given calculation and help ease the data motion bottleneck on modern computer architectures.
