Sparse Format Specialization

Sparse Format Specialization The processing time of sparse representations of local discrete operators depends heavily on the storage format. The requirements of high accuracy, minimal memory footprint, high data locality, parallelism friendly layout, wide applicability, and easy modifiability are contradicting and therefore only case specific choices lead to satisfactory results.

Data Layout Abstractions

Data Layout Abstractions Data layout has tremendous impact on performance, in particular for high throughput devices. But traditional languages force the programmer to specify the memory layout of multi-valued data containers in a syntax that makes it impossible to change later without modifying all accesses to the data container. Data layout abstractions allow to switch between array of structs and struct of arrays layouts with a single parameter while keeping the traditional syntax.
