Intel’s new OpenCL SDK gives access to on-die GPU
Intel have just released their OpenCL Software Development Kit (SDK) for Intel processors. The good news is that this version targets the on-die GPU as well as the CPU allowing truly heterogeneous programming. The bad news is that the GPU goodness is for 3rd Generation ‘Ivy Bridge‘ Processors only– us backward Sandy Bridge users have been left in the cold :(
A quick scan through the release notes reveals the following:-
- OpenCL access to the on-die GPU part is currently for Windows only. Linux users only have CPU support at the moment.
- No access to the GPU part of Sandy Bridge Processors via this implementation.
- The GPU part has single precision only (I guess we’ll see many more mixed-precision algorithms from now on)
I don’t have access to an Ivy Bridge processor and so can’t have a play but I’m looking forward to seeing how much performance OpenCL programmers can squeeze out of this new implementation.
