We have a small OpenCL library written a number of years ago which has been working well until recently. Now, with recent Intel GPUs (UHD Graphics 620 and 630), the Intel library (
igdrcl32.dll) frequently throws an exception (
0xc0000409) as soon as
clSetKernelArg() is called after
clReleaseMemObject() has been called and new mem objects have been created. Has anyone here seen such a problem or have any idea where to look? I wanted to post a question on the Intel OpenCL forum, but every time I try to access any Intel forum, their website takes me to a registration page where i have registered numerous times, so I do not expect to get any help from Intel.
