What is OCCA?

In a nutshell, OCCA (like oca-rina) is an open-source library which aims to

• Make it easy to program different types of devices (e.g. CPU, GPU, FPGA)
• Provide a unified API for interacting with backend device APIs (e.g. OpenMP, CUDA, OpenCL)
• Use just-in-time compilation to build backend kernels
• Provide a kernel language, a minor extension to C, to abstract programming for each backend
