To anyone interested and maybe related to some [other questions](https://discourse.julialang.org/t/should-you-use-spawnat-everywhere-within-a-package-distributed-jl/112134), what works for me is to add

```julia
module MyPkg
using Distributed
f(x) = ...
function big(...)
  ....
  return pmap(f, iterator)
end

export big
end

```

Then outside the pkg I just need to do

```julia
using Distributed
addprocs(10)
using MyPkg
@everywhere using MyPkg
big(...) # works and is faster!

```

It is very simple to modify existing code to make it distributed that way.  
If I don’t want distributed, I just do not load `using Distributed` and `pmap` performs as a regular `map`.
