Two nodejs apps on two cores?

Question

Node.js

There are two completely different applications on nodejs, there is a 4-core server, how can I run these two applications each on a separate core?
I googled, found cluster, but as I understand it, it just can run the same application on several cores, and I need 2 applications - 2 different cores.
I also use pm2

Answer 1

What is there to invent? You start two node processes and that's it.

node first_app.js
node second_app.js

Well, with pm2, as far as I understand, you just need to replace node with pm2 start.
You will start two different processes. The operating system itself will scatter them over different cores if possible and necessary.
