Example: Allocating on a specific NUMA node

In the following basic example, we explicitly allocate arrays on specific NUMA nodes.

julia> using NUMA, Random

julia> x = Vector{Float64}(numanode(1), 10); rand!(x);

julia> which_numa_node(x)
1

julia> y = Vector{Float64}(numanode(6), 10); rand!(y);

julia> which_numa_node(y)
6
