[Question] Why using --cpu 0 in hmmer ?

[jeanrjc]

Is there any reason as to why you set --cpu 0 in the hmmer command instead of --cpu 1 :

macsyfinder/macsypy/profile.py

Line 185 in 313cd5f

command = f'"{self.cfg.hmmer()}" --cpu 0 -o "{output_path}" {hmmer_threshold} ' \

In the hmmer documentation, it's written that :

If you specify --cpu 0, a HMMER search program will run in serial-
only mode, with no threading. We use this in debugging when we
suspect something is awry with the parallel implementation, but it’s
not something you’d generally want to do in your work. Even with a
single worker thread (--cpu 1), HMMER will be faster than serial-only
mode, because the master thread handles input and output.
