SYCL DPC++ auto detect device

aamirkhann — Mon, 04 Jul 2022 11:33:43 GMT

This question might be trival, unfortunately I haven't found the answer I was looking for. I used DPCT migration tool to port some cuda code to intel DPC++ and then I further optimized everything I needed and eventually got rid of everything related to DPCT expect the super handy

dpct::get_current_device();

which basically solves all the previous pain I had to put compile options to select the appropriate device and control them with Makefiles and so on.

Is there any way to do this without using dpct ? I had a look at how dpct does this (here) but it looks pretty non_straightforward and it relies on other internal functions.

Is there any way to avoid this ?

Hi,

Thanks for reaching out to us.

You can try replacing dpct::get_current_device() with

q_ct1.get_device().get_info<sycl::info::device::name>()

For more information refer the below link:
