OpenCL problem with Windows on Intel integrated CPU

[iopq]

I first waited for the tuning to finish then whenever I launch it it spits out

KataGo v1.2
Using OpenCL Device 0: Intel(R) HD Graphics 5500 (Intel(R) Corporation) OpenCL 2
.0
Loaded tuning parameters from: ./KataGoData/opencltuning/tune_gpuIntelRHDGraphic
s5500_x19_y19_c96_mv5.txt
Uncaught exception: CL_BUILD_PROGRAM_FAILURE
BUILD LOG FOR xgemmDirectProgram ON DEVICE 0
fcl build 1 succeeded.

and then it quits

@Naphthalin posted a very similar error to yours with Intel HD Graphics 4600, where it tuned successfully, then failed to build when actually using the parameters (despite building successfully when tuning). "fcl build 1 succeeded" is supposed to be the error message when building, which strangely sounds like a success!

I think the answer might be that Intel HD Graphics OpenCL is simply buggy. At least, I'm not sure there's much I can do here. See CNugteren/CLBlast#280

try 32bit version, my 4400 works on it

32bit didn't work, LeelaZero works fine for some reason

I did the tuning again to see what happened

Tuning xGemmDirect for convolutions
Testing 56 different configs
WARNING: Reference implementation failed: CL_BUILD_PROGRAM_FAILURE
Tuning 20/56 ...
Tuning 40/56 ...
ERROR: Could not find any configuration that worked

Does the current 1.3.2 engine work with intel graphics for anyone? if so, which intel graphics generation do you have?

Seems basically the same as #78, and also a pretty old issue so closing this issue and just leaving the other one open for user visiblity.
