Note that 5 out of 7 samples in here use the Update feature which for intel GPUs is available only with embargoed drivers and hence not available to the users just yet. It's currently possible to use those examples on AMD and Nvidia backends though. AFAIK this will become available in L0 drivers in the coming months. @jimmytwei, What is your preference in terms of adding those limited working samples now or later, when the feature is available for intel gpus?

First round of comments ...

Do we also want to add a graphified version of an existing example like:
https://github.com/reble/oneAPI-samples/blob/sycl-graph/DirectProgramming/DPC%2B%2B/StructuredGrids/1d_HeatTransfer/src/1d_HeatTransfer.cpp

More samples is a good idea IMO. But given the current scope of this work, I think it'd be more manageable to add it in a follow-up PR.

@konradkusiak97 My suggestion is to add in those samples later. The samples in this repo need to compile and run with the latest oneAPI toolkits and drivers. We don't want to submit something that won't work in the current or the next release.

@konradkusiak97 Both samples compile and run successfully but with no output. It'll be great to output some sort of message to indicate that the sample ran successfully or failed.

I added code verifying the results and it prints a message on successful execution.
