clCreateKernel fails with CPU selected

Hi, i have simple kernel.

When i use intel offline compiler ioc32.exe clCreateKernel fails with error code INVALID_VALUE

When I recompile the kernel for Intel 4600 GPU clCreateKernel succeeds.

How i can obtain more debug information why it fails on the cpu?

I have traces and ir files if needed.

Hi Stefan,

1. Could you please provide the kernel? (you can send a private message to me if you do not want to post it in the open)

2. Could you please specify command line parameters to ioc32 that you use to build your .ir file?

Maybe this article could shed some light on this issue: https://software.intel.com/en-us/articles/using-spir-for-fun-and-profit-with-intel-opencl-code-builder - note the differences of compiling a kernel for the 32-bit CPU vs GPU (that one is always 64 bit).
