You are probably right, cause that file doesn't even exist. I looked at default gnuradio-core.conf in conf.d.
I suppose that something like that should be written in gnuradi-core.conf, but really nothing.
Where can I find which option should be added?
How are you determining that this is only occupying a single core?

Are you running on a VM?   If so, how many cores does your VM simulate?

Hi all guys,

I have a flowgraph where I have three parallel paths for filtering signal stored in a file. Here the picture of my flowgraph:

Inline image 1

I use gnuradio When I run the script it uses only one processor, and since I have 4 cores, I would like to run every of the paths on another processor. For every filter I do set_processr_affinity[some number between 0 and ]. When I run the script nothing changes, it still runs on a single core. Am I missing something with set_processor_affinity method?

My guess is that your ~/.gnuradio/config.conf   specifies to use the single-threaded scheduler.
