PARI/GP parallelism?

being a computer algebra system, i thought that PARI/GP was suited to solve some PE problems faster -- i'm particularly intrigued by it having parallel computing built in.

however my GP says "threading engine: single", and i suspect that doing parallel versions for (parfor) doesn't actually parallelize it. i tried to look this up, but it seems that i had to configure it while building it from source, which is something i would like to avoid.

is this a setting that can only be changed by building from source, or is there a setting somewhere to change the threading behavior of GP?
