Hi Kuljeet,

I have gone through your code. I can see that you haven't specified inputData and outputData argument to the image<2> constructor. Advising you to make the following changes to your code on line numbers 154 and 155.

On line number 154, From cl::sycl::image<2> image_in(co::rgba, ct::unorm_int8, imgRange); (your code) to cl::sycl::image<2> image_in(inputData,co::rgba, ct::unorm_int8, imgRange); (suggested change)

On line number 155, From cl::sycl::image<2> image_out(co::rgba, ct::unorm_int8, imgRange); (your code) to cl::sycl::image<2> image_out(outputData,co::rgba, ct::unorm_int8, imgRange); (suggested change)

Let us know if the suggested changes resolve your issue.

Rahul

Many thanks Rahul,

Many thanks Rahul,

I was able to execute the code sucessfuly with the changes suggested.

Is there any document that captures the differences / enhancements between DPC++ and SYCL1.2 ?
