[gmx-users] AMD GPUs

[Szilárd Páll]

I was referring to the OpenCL port. We are working with the
Streamcomputing guys on the OpenCL port, the code is in review at the
moment. We expect to have OpenCL for AMD and NVIDIA (for demonstration
purposes only) support in the next release.

If interested, grab the code here:
