Hi folks,
I apologize for this basic question but I have not been able to resolve this by going through the documentation. How does one create a GPU array from an Array using KernelAbstractions? Similar to CuArray(array)? In the 2021 JuliaCon tutorial there are references to a GpuArray function but that does not seem to be part of the API anymore. The only way I can see doing this now is to use alllocate() and then copyto!(). Is this the best way?
Thanks.

adapt(backend, array) should work. otherwise allocate + copyto! indeed.
