Re: [Haskell-cafe] Find out which part of code are causing parallelism?

however I just found out that without inserting any parallism manually the program is already parallelised,

That's not your program, it's the garbage collector. "By default, all of the capabilities participate in parallel garbage collection." https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/runtime_cont... - J.W.
