In this work, we propose to decouple the arithmetic format from the storage format in numerical algorithms. We complement this idea with a modular precision storage layout that allows runtime precision adaptation such that a value can be accessed faster if lower accuracy is acceptable. Combined with precision-aware numerical algorithms that use full precision in all arithmetic computations, this strategy can result in runtime savings without impacting the memory footprint or the accuracy of the final result. In an experimental analysis using the adaptive precision Jacobi method we assess the benefits of the modular precision format on a recent high-end GPU architecture.
