I have a HP Z230 PC with an integrated Intel HD 4600 GPU.
On this PC with Windows 7 64bit, my OpenCL program runs correctly. After upgrading to Windows 10 64bit, the call to clSetKernelArg fails and returns CL_INVALID_ARG_SIZE. No code changes on my side.
On windows 10, the driver version is 10.18.15.4256. I tried to upgrade to the newest driver version (15.40.4.64.4256). The installation seems to succeed, but installs version 10.18.15.4256 again.
I also installed INDE 2015 update 2. The installer complains that the OpenCL driver is missing or out of date, but gives the option to install INDE anyway, which I did. The command line OpenCL compiler, ioc64, is not working however. It just doesn't produce any output. Using the INDE OpenCL code builder, building the OpenCL kernel produces error message IOC engine exited with code -1073740791.
So the current status is:
- OpenCL code that runs fine on Win7, does not run on the same hardware on Win10: clSetKernelArg returns CL_INVALID_ARG_SIZE.
- Trying to install the newest OpenCL driver for the HD 4600 on Win10 just reinstalls the current driver
- INDE 2015 update 2 does not compile an OpenCL kernel on Win10: it doesn't produce any output using the command line compiler. Using the INDE IDE it produces the error message above.
My suspicion is that there is something not right with the driver. Can anyone confirm that, or point me to another possible cause? Thanks in advance!
