%description
OCCA is an open source, portable, and vendor neutral framework for parallel programming
on heterogeneous platforms. The OCCA API provides unified models for heterogeneous
programming concepts—such as a device, memory, or kernel—while the OCCA Kernel Language
(OKL) enables the creation of portable device kernels using a directive-based extension
to the C-language.

Mission critical computational science and engineering applications from the public and
private sectors rely on OCCA. Notable users include the U.S. Department of Energy and Shell.

Key Features:

- Multiple backends—including CUDA, HIP, Data Parallel C++, OpenCL, OpenMP (CPU), and Metal
- JIT compilation and caching of kernels
- C, C++, and Fortran language support
- Interoperability with backend API and kernels
- Transparency—easy to understand how your code is mapped to each platform
