The accelerate package

[Tags:bsd3, library]

This library defines an embedded language for regular, multi-dimensional array computations with multiple backends to facilitate high-performance implementations. Currently, there are two backends: (1) an interpreter that serves as a reference implementation of the intended semantics of the language and (2) a CUDA backend generating code for CUDA-capable NVIDIA GPUs.

To use the CUDA backend, you need to have CUDA version 3.x installed. The CUDA backend currently doesn't support Char and Bool arrays.
