Problem with GPU execution and usm::alloc::device

Hi Arthur,

I was trying to run your example in devcloud and after solving some problems with library paths I have encountered the following error when reserving memory for the GPU:

Did you encounter any problems like this or could it be a problem derived from the new oneAPI implementation?

Thank you for your time.

It seems to be a compatibility problem with usm_allocator: intel/llvm#2026
In this link it is clear that the use of usm::alloc::device is no longer allowed.
