WebApr 29, 2024 · SharedArrays are shared across processes (separate workers in Julia). Obviously SharedArrays require shared memory. Usually separate workers on same machine, rather than workers distributed across cluster. Standard arrays are local to each process (Julia worker) only. But can be “shared” across threads.
