this is a tricky part.
If your simulations take comparable amount of time, I would use
yadedaily-batch -j 12 --job-threads 3 ...
to use 12 cores, but to decrease "parallel overhead"
If your simulations differ very much in length, you can use --job-threads 12 not to wait too long for unfinished jobs.
BUT, it may happen that using 12 cores take more time then, e.g., 6 cores :-)
So to take really "full advantage of CPU", you have to play a bit :-)
