[Mesa-users] Status of MesaGL on headless GPU machines

[Biddiscombe, John A.]

OK. I suspected that I wouldn't find an off-the-shelf solution. 

If I ignore cuda and just want hardware accelerated GL, can I find what I need on the wiki? I didn't manage to locate the info yet (any hints to links appreciated).

This morning some NVidia people were in the building and I asked them about a cuda+GL solution for HPC machines and they have offered their assistance, so I'll report back if any solution is out there.

Thanks

JB

I think your best shot at Cuda-OpenGL integration will be with NVIDIA's own Cuda/OpenGL drivers.  I don't follow Mesa's support for NVIDIA GPUs too closely, but I doubt anyone's really addressed Cuda interoperability.
