Can OpenCL now run Intel OneAPI devcloud?

In Past solutions ,This method cannot be used anymore because there is no clang compiler.

clang ocl_vecadd.c -o ocl_vecadd -lOpenCL -lm -I/opt/intel/inteloneapi/compiler/latest/linux/include/sycl/ && ./ocl_vecadd

 I have tried to replace clang with icpx, but I cannot obtain the result. The following error is reported:

/usr/bin/ld: /tmp/icpx-b9b022/gpu_sample-4f1f6b.o: in function `main':

icpx: error: linker command failed with exit code 1 (use -v to see invocation)

Is there any way to run it now or is it not supported?

Hi,

 

Thank you for posting in Intel Communities. We could run a OpenCL sample with the below command in oneAPI command in node-s019-n011.

icpx -I/opt/intel/oneapi/compiler/latest/linux/include/sycl -lOpenCL openclsample.c

 

However, we are not able to run the binary executable and would end up with segmentation fault error. Please let us know you've observed the same.

If the above command doesn't work for you, we would like to look at your OpenCL sample code. Could you please share it?

 

Please accept this as a solution if this helps resolving your issue. This helps others with similar issue. Thank you!

 

Regards,

Alekhya

Thank you. This method is very effective. In addition, replacing dpcpp with the above command 'clang' also has the same effect。
