The <DPC++ API name> call is used instead of the <CUDA API name> call. These two calls do not provide the same functionality. Check the potential precision and/or performance issues for the generated code.

Detailed Help

The Intel® DPC++ Compatibility Tool did not find an exact functional equivalent of the function in DPC++, so it used the closest alternative. The replacement may impact your code precision and/or performance. Verify the code correctness/performance.

Suggestions to Fix

Verify the code correctness/performance.
