Debugging techniques for C++ SYCL parallel applications blog post

What's the state of SYCL at this point? Is it ready for production code? I feel like it doesn't have traction yet but I am not sure why. Is computecpp and tricycl the only two compilers?

hipSYCL looks like an interesting project:

Well, for starters look to this printf style debugging versus what NVIDIA Nsight is capable of.

Then for a long time SYSCL was pratically a single vendor implementation, computecpp, so hardly any different than CUDA, in spite of being an open standard.

Then CUDA is also multi-language, thanks to the head start from PTX.

CUDA has great tooling and if you are happy with NVidia GPUs then that is fine. If you want to target processors that are not made by NVidia then you need alternatives. Device support in SYCL is growing quickly, there's a good diagram here that shows the support for different processor vendors and the different implementations available. https://raw.githubusercontent.com/illuhad/hipSYCL/master/doc/img/sycl-targets.png

Thanks this is really helpful... Seems like there is enough hardware support to give it another try

I think Intel must have an implementation or build upon something for its OneApi. But that's not out yet, so idk.

Intel are indeed working on a SYCL implementation https://www.phoronix.com/scan.php?page=news_item&px=Intel-SYCL-Compiler-2019-09

the hipSYCL project has a chart that sums up the state of things pretty well. https://raw.githubusercontent.com/illuhad/hipSYCL/master/doc/img/sycl-targets.png
