@bennedich thank you for the link.  
To answer your question, this code was just a super simple example I made up to understand the basics of multi-threading. The original problem I posted is available at: [https://discourse.julialang.org/t/problems-using-pmap-and-doubt-about-the-number-of-workers-processes-to-use/20510](https://discourse.julialang.org/t/problems-using-pmap-and-doubt-about-the-number-of-workers-processes-to-use/20510)  
(See also my second comment on it, in which I provide further details).

About the link you posted, let me ask you the following. You clearly distinguish between either:

> multi-threading (single computer, multiple cores), or parallel computing (cluster, several distributed machines)

In my case I am using one multi-core computer. Does that mean that I cannot use parallel computing at all (and thus `pmap()`)?
