Abstract

LLAMA is a cross-platform C++17/C++20 header-only template library for the abstraction of data layout and memory access. It separtes the view of the algorithm on the memory and the real data layout in the background. This allows for performance portability in applications running on heterogeneous hardware with the very same code.
