DPC++ for NVIDIA/CUDA devices on Windows

pclausen — Thu, 14 Jan 2021 08:34:25 GMT

Hi,

I downloaded the oneAPI BasiKit and then oneAPI HPC on windows. I could run a sample code both from Visual Studio (2019) and also generated from cmake (3.19.2). The sample code compiles and runs. I have both an Intel Graphics 630 card and a NVIDIA Quadro M2200 card, but I can't see the NVIDIA device (see file attached); I also don't understand what the device [0x591b] refers to. Note that I can successfully run a CUDA examples in Visual Studio and also generated from cmake. From what I read, it seems that using DPC++ for CUDA devices is experimental and was tested on Linux only, but I am not sure. Is there a way to use it now on windows? If not, what is the time expectation to have it working on windows?

Thank you

Hi pclausen, are you using oneAPI on FPGA devices? Could you please specify the Intel devices/products that you're using in your design?

Hi, I plan to use it in the future, but currently I want to test it on CUDA gpu card but it does not work. My interest of using sycl-DPC++ is to be able to use it for multiple devices, including CUDA device. I have it working for my intel gpu card, but not for the CUDA card. Should I expect it to work on CUDA ot not? If not, what is the best solution to have my code working on both intel and cuda devices?

Hi Pascal,

Thank you for your interest. We do not support DPC++ with CUDA BE on Windows at this point and have no plans for it in near future.

Thanks.
