What is the cause of this problem? look forward to your reply

[ddemidov]

Can you try this?

OCL_DEVICE=i7-8700 ctest --output-on-failure

This will exclude the HD Graphics device from the tests (well, in fact it will restrict the tests to the device that has "i7-8700" in the name, but the effect will be the same). I think opencl driver for Intel graphics devices has some limitations.

[zsw667291]

i use command
OCL_DEVICE=i7-8700 ctest --output-on-failure

fix the problem of fft , but the problem of sort & simple_cmake_build still exist

[ddemidov]

Not sure why do you get the simple_cmake_build failure (could cmake configure go wrong? you could try to clean up the build directory and try to reconfigure), but I think that can be safely ignored.

I can reproduce the segfault error with Intel OpenCL, but not with NVIDIA CUDA or OpenCL. The sort code is ported from ModernGPU code, which targets NVIDIA CUDA, and is quite big, so I am not sure when I will have time to take a closer look at this.

I'll keep the issue open as a reminder for myself.
