NUMA tools (from libnuma) for Julia

Documentation	Build Status	Quality

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

• NUMA.jl is an effort by the Paderborn Center for Parallel Computing (PC²).
• ArrayAllocators.jl and specifically NumaAllocators.jl has served as an inspiration (and provides similar functionality).
