Let’s say I have a function `f`

where I do something with the `i`

th column of a matrix available to all workers (~40). I then return an array of `Any`

and length 4:

```
@everywhere function f(i:Int)
//do something with the i-th column of matrix
ret = Array{Any}(undef, 4)
// write results to ret[1] to ret[4]
return ret
end
function main()
ret = pmap(f, 1:N)
end
```

When I do `ret = pmap(f, 1:N)`

where N is large (e.g. 10k), is it guaranteed that the `ret`

will be in order, i.e. the `ret[i]`

will be the results from the `i`

th column?

I ran a test case where N = 200 and seems like it is. If it actually is, then I won’t need to change my implementation.
