Following OpenCL technology progress: #47

Hi guys, recently I came across the following information: (http://en.wikipedia.org/wiki/OpenCL#OpenCL_1.2) "OpenCL 2.0. On November 18, 2013, the Khronos Group announced the ratification and public release of the finalized OpenCL 2.0 specification. Updates and additions to OpenCL 2.0 include:

Shared Virtual Memory Nested Parallelism Generic Address Space Images C11 Atomics Pipes Android Installable Client Driver Extension Industry Support"

About hardware supporting OpenCL 2.0: (http://stackoverflow.com/questions/23745612/hardware-supporting-opencl-2-0) "At present, there are no conformant implementations of OpenCL 2.0 available.

In terms of hardware support, AMD have stated that some of their latest GPUs have the capabilities for OpenCL 2.0, and I would expect that most (if not all) modern CPUs have too (Xeon Phi likely does as well). NVIDIA's latest GPUs are probably also compliant, since they have CUDA equivalents of nested parallelism and SVM.

So, we are just waiting for the actual implementations (i.e. drivers) to appear. At IWOCL'14 last week it was mentioned that the conformance package for OpenCL 2.0 was only just finalised recently, so we can expect to see these implementations start to appear in the coming months.

In the meantime, AMD have preliminary support for some OpenCL 2.0 already available in their latest beta driver."

@a-palyanov what ever happened with this? :)

a-palyanov commented 8 years ago

@slarson Here is a list of devices which support OpenCL 2.0: https://www.khronos.org/conformance/adopters/conformant-products#opencl

Our R290X in in the list, but it requires (as well as all other devices) Windows 8.1 64 bit. Or Red Hat Enterprise 6.5 (64-bit version) or Ubuntu 14.04 (64-bit version).

Here is a link to choose and download the driver: http://support.amd.com/en-us/kb-articles/Pages/OpenCL2-Driver.aspx
