Configure dpcpp floating-point precision

Jonas5 — Mon, 16 Jan 2023 09:51:27 GMT

What is the preferred way of configuring floating-point precision on dpcpp?

I have previously found a macro for configuring this from SYCL, but I'm unable to find the documentation for it now.

My device does not support double fp, and I want it disabled.

Could you please let us know which macro you found from SYCL?

You can disable the double fp using the below pragma

#pragma OPENCL EXTENSION cl_khr_fp64 : disable

Thanks & Regards,
