Define the struct everywhere according to

```julia
@everywhere struct Ctrl
    n::Int64
    q::Bool
end

```

This defines the struct on all workers that are running while the struct is defined, so start your workers before defining the struct like above.

PS: also, don’t forget to [quote your code](https://discourse.julialang.org/t/psa-how-to-quote-code-with-backticks/7530)
