How to run a file/script in the Linux terminal (Ubuntu) assigning multi-threading?

Hi Folks,

Could anybody guide me, please?

How to run a file/script in the Linux terminal (Ubuntu) assigning multi-threading? If in the first line of the script I use #!/path/of/bin/julia it works without multi-threading. However, when I tried to use multi-threading by modifying that line as #!/path/of/bin/julia --threads 4 it does not work.

Thank you so much in advance

Cheers

Boris

What do you mean by “it does not work”? What happens if you do this:

[nils@nils-folio1040g1 ~]$ julia --threads 4
