Hello,  
I’ve set the number of threads to be 12 in Julia extension in VScode. However, when I check it in Julia REPL it shows 1. Any recommendation to solve it?

Thanks!

You start a separate julia from powershell. This Julia doesn’t know about the VS Julia settings.

Start Julia with  
View → Command Palette → Julia: Start REPL

Thanks, yes I followed your way and it works. So, there is no way to start Julia form powershell and let it know about VS Julia settings?

I don’t think so, but you can run Julia from the powershell with

```julia
julia -t 12

```

for 12 threads.  
see [Command-line Options · The Julia Language](https://docs.julialang.org/en/v1/manual/command-line-options/#command-line-options)
