How to use two tiles with oneapi 2022.1.0?

[nahso]

Hello,
I am using ATS-P gpu, and I created a queue with gpu_selector, submitting a parallel_for task to the queue. The vtune profilling result shows only one tile(tile 0) was used, but I can not find APIs to explicitly use two tiles.
Therefore, how can I use two tiles?

I have received your request. Thank you for raising it.

I hope the following link will give you sufficient information about using multi-tile Intel GPUs:

https://intel.github.io/llvm-docs/MultiTileCardWithLevelZero.html

There are comments on how you should change your code to support 2 tiles and in the very end there are links to examples.

We will no longer monitor this thread. Hope the link I provided earlier answers your question.

If you require additional assistance from Intel, please start a new thread. Any further interaction in this thread will be considered community only.

Thanks!
