You machine will TF to 77 after the P-1 is finished, by default. Then the LL will start.

What Mini-Geek said is correct in that if you want to speed the test compared to the wall clock, then a multicore is the way to go. If you want to be most efficient then there are other things to do.

Remember, if you do things in parallel (lower TF on 1 machine, P-1 on another, ECM on a 3rd, high TF on a 4th and LL on a 5th), if you find a factor below 76 (for example), then all the other effort is wasted.
