I have access to a new university machine which runs 4x AMD® Opteron™ 6212 processors, but has no separate GPU. And now I'd need to get OpenCL working here. The machine runs Gentoo linux, this may be a bit of an unhappy choice but I have no say in that.
I wonder how find and install the proper OpenCL drivers. I can find drivers for the AMD GPUs, but there is no separate GPU, so that's probably not the best idea. I can find drivers for the Intel CPUs, but they are AMD CPUs. I can find windows-only drivers with auto-detect, so which work for just the CPU, but they are windows-only and I run Gentoo linux.
So how should I find and install the drivers to actually run my programs on this new machine?
