How is SYCL debugging on windows recommended?

[Martin-HZK]

Hi, I am trying to do some contribution to SYCL inference support on Windows, but I am not sure if there is any recommended strategies for debugging the inference process?

@Martin-HZK
For the CPU code, you could use common method to debug as windows development.
For the SYCL code part, you could print log method (like sycl::stream).

Hi, Jianyu. Thank you for your advice. If I switch to linux, are there any practical debugging tools like GDB for SYCL? I am not sure if I need to switch to Linux for convenience.

This is what Neo is referring to: https://stackoverflow.com/a/59071765

DPCPP also provides a printf implementation if you don't want to use the streams:

// Some device code
sycl::ext::oneapi::experimental::printf("Foo %d, Bar %.4f", foo, bar);

No! GDB is not recommended for SYCL code on device. But it's OK for SYCL code on CPU (I didn't try it).

The debug method on Linux is same as Windows.

Many thanks!
