I had a similar problem a couple of days ago ([Correct usage of SharedArray and @parallel?](https://discourse.julialang.org/t/correct-usage-of-sharedarray-and-parallel/2979)).

Basically, you need to add `@sync` in front of `@parallel` to force the available threads wait for the end of loop operations before doing something else.
