%description
ArrayFire is a high performance software library for parallel
computing with an easy-to-use API. Its array based function set makes
parallel programming simple.

ArrayFire's multiple backends (CUDA, OpenCL and native CPU) make it
platform independent and highly portable. ArrayFire provides
visualization capabilities using our OpenGL-based, high performance
visualization library.

A few lines of code in ArrayFire can replace dozens of lines of
parallel computing code, saving you valuable time and lowering
development costs.
