The Gang scheduling function has the func-
tion of simultaneously allocating the required
number of CPUs when scheduling parallel
programs, and allows you to obtain almost
the same performance when multiple parallel
programs are simultaneously executing, as if
the programs were running alone.
I have approximately zero interest in this myself, but something seemed
off about the definition of gang scheduling being used in the post.
