How to efficiently handle parallelism on a DistributedArray

[kfrb]

@ultrapoci and @deltaeecs, I had a similar problem and solved it using multithreading. See the old thread for an MWE:

Performance issues with parallel Julia code

Thank you very much @goerch for your detailed comments and helpful information, which helped me to improve the performance significantly! However, after further research, I decided to also give multithreading a try, as it seems to be better suited for this use case. A slightly better simulation-adapted MWE looks like the following.
