I've installed 2016R2 (had previously installed 2015Rx).
The following is reported on my Windows 7:
Intel(R) Corporation OpenCL 1.2 - Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz - Intel(R) HD Graphics 4000 Intel(R) Corporation OpenCL 2.1 - Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz
However OpenCL 1.2 CPU stopped working. Although CPU device is found the context fails to be created:
Context::Context() failed (CL_DEVICE_NOT_AVAILABLE)
This problem should be easily reproducible using CodeBuilder Project for Windows VS2015 template. Compilation fails on:
1>------ Build started: Project: OpenCLProject2, Configuration: Release Win32 ------ 1> Preprocessing: Template.cl 1> Ignoring -TARGETOS option - not supported for current CPU runtime version 1> Setting target instruction set architecture to: Default (Advanced Vector Extension (AVX)) 1>C:\dev\OpenCLProject2\Template.cl : error CL: Failed to create context for OpenCL Intel CPU device...: -2 (CL_DEVICE_NOT_AVAILABLE) 1> Build failed! 1> 1>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\BuildCustomizations\IntelOpenCL.targets(98,5): error MSB3721: The command ""C:\Program Files (x86)\Intel\OpenCL SDK\6.1\bin\x86\ioc32.exe" -cmd=build -input="C:\dev\OpenCLProject2\Template.cl" -output="Release\Template.out" -VS -device=CPU -simd=default -targetos=current -bo=" "" exited with code -1. ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
Could you please let me know what graphics driver are you using?
