The Best of Both Worlds: Bringing Back the Intel® SDK for OpenCL™ Applications

We are bringing back the standalone Intel® SDK for OpenCL™ Applications. Leah posted a nice article explaining the reasoning behind this decision: https://software.intel.com/en-us/blogs/2015/11/13/bringing-back-the-intel-sdk-for-opencl-applications.

RFE: Intel native one workitem per hardware thread kernel that supports register regioning

Here's a pie-in-the-sky request for enhancement... :)

It would be useful if we could create OpenCL/SPIR-* kernels that mapped one workitem to a single EU hardware thread and exposed the thread's entire 4KB/thread GRF.

Add to this a "Gen Native" OpenCL extension that exposed register-regionable explicit SIMD operations.

Image Read Failure in OpenCL

I am trying to use OpenCL to create a 3D texture and read in the kernel (clCreateImage). The texture read always returns 0 on Intel GPU device, but it works ok on CPU device. I wrote a simple test program to reproduce the problem if there is a way to attach the program here. This was tested under the Intel HD Graphics 520 and 5500 platform. I am using the latest Intel OpenCL SDK and drivers on Windows 10.

Is image function actually supported in Intel OpenCL?
