ABOUT

LibFlatArray acts as a highly efficient multi-dimensional array of arbitrary objects (array of structs, AoS), but really uses a struct of arrays (SoA) memory layout. It's great for writing vectorized code and its lightning-fast iterators give you access to neighboring elements with zero address generation overhead.

Use cases include:

• computer simulations (e.g. stencil codes such as Lattice Boltzmann Methods)
• image processing (e.g. Gaussian filters)
• numerical methods (e.g. multiplication of complex matrices)

The library is written in C++ and uses templates to shift the burden of address computation from runtime to compile time. It shares some infrastructure with its parent project LibGeoDecomp.

DEPENDENCIES

• C++ compiler (min. C++98, tested with GCC's g++, Clang's clang++, and Intel's icpc)

• CMake (min. 2.8.10)

• build tool supported by CMake (e.g. make, ninja)

BUILDING

For compiling LibFlatArray you'll need CMake (http://www.cmake.org) installed. We recommend an out-of-source build:

BUILD_DIR=build/uname -ms | sed s/\ /-/g mkdir -p $BUILD_DIR cd $BUILD_DIR cmake ../../ make
