Atomix

Atomix.jl implements @atomic, @atomicswap, and @atomicreplace that are superset of the macros in Base. In addition to atomic operations on the fields as implemented in Base, they support atomic operations on array elements.

julia> using Atomix: @atomic, @atomicswap, @atomicreplace

julia> A = ones(Int, 3);

julia> @atomic A[1] += 1;  # fetch-and-increment

julia> @atomic A[1]
2

julia> @atomicreplace A[begin+1] 1 => 42  # compare-and-swap
(old = 1, success = true)

julia> @inbounds @atomic :monotonic A[begin+1]  # specify ordering and skip bound check
42

julia> @atomicswap A[end] = 123
1

julia> A[end]
123
