I just installed the latest update of the OpenCL Applications 2017 SDK (the one released a few days ago) and the experimental OpenCL CPU-runtime is no longer working. When I run clinfo, I got a -11 error on clBuildProgram:
Platform Name: Experimental OpenCL 2.1 CPU Only Platform
Number of devices: 1
Device Type: CL_DEVICE_TYPE_CPU
Vendor ID: 8086h
Max compute units: 12
Preferred local atomic alignment: 0
5 errors generated.
The previous Experimental runtime was working fine. I'm using Windows 10 Pro 64 bit, I've Visual Studio 2013 installed (I also installed the Intel OpenCL SDK plugins for VS) and also have the Intel OpenCL CPU-only 16.1.1 runtime (in addition to the AMD drivers with respective OpenCL runtimes).
I wonder if something was corrupted during install? There are a few places you could check.
- In Visual Studio: Code-Builder->Platform Info should show your OpenCL implementations, including the Experimental OpenCL 2.1 CPU Only Platform.
- Do you see intelopencl64_2_1.dll in
HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendorsas described in https://www.khronos.org/registry/OpenCL/extensions/khr/cl_khr_icd.txt?
- Do you see intelopencl64_2_1.dll in C:\Windows\System32?
Re-install may get this working.
Thanks, I uninstalled the SDK since it also corrupted my VS2013 and I wasn't anymore capable of opening my solutions.
I think something went quite wrong during the installation, although no errors or warnings were shown. If it can help, I installed the SDK from the Intel Software Manager and not by downloading the SDK as standalone.
Since I'm working on a corporate machine, I'll live without the SDK for now, which is not strictly required for my tasks. In case I'll reinstall it one day, I'll let you know.
