A CUDA Back-End For Intel's Open-Source Driver?
Phoronix: A CUDA Back-End For Intel's Open-Source Driver?
While there is the "Clover" branch of Mesa started by Zack Rusin for providing an OpenCL state tracker that can be used by Gallium3D hardware drivers, it hasn't yet amounted to much. The OpenCL state tracker is not yet working, hasn't been touched in months, and has yet to be integrated in the mainline Mesa code-base. However, as another GPGPU alternative, it looks like a CUDA back-end that's specific to Intel's open-source driver may end up being worked on...
