Gdev is a rich set of open-source GPGPU runtime and driver software.
Currently it supports NVIDIA GPUs but is also portable to other GPUs.
The supported API implementaions include:
+
"Gdev API": A low-level API to manage details of GPUs.
"CUDA Driver API": A low-level API adovocated by NVIDIA.
"CUDA Runtime API": A high-level API adovocated by NVIDIA.

The implementation of CUDA Driver API and CUDA Runtime API is built
on top of Gdev API. For CUDA Runtime API we make use of GPU Ocelot as
a front-end implementation. You can add your favorite high-level API
