I have tested with the latest master:
add https://github.com/JuliaGPU/oneAPI.jl#master
And my result ( gen8 cpu; julia 1.6.1; ubuntu 20.04 )
julia> using oneAPI
julia> a = oneArray(rand(Float32, 2,2))
2×2 oneArray{Float32, 2}:
0.233732 0.297938
0.924481 0.541995
julia> a .+ 1
2×2 oneArray{Float32, 2}:
1.23373 1.29794
1.92448 1.54199
