Hi all,
Seeing that not every time a stage 1 gcd will result in a factor found, are
we not better to wait until the end of stage 2? This way, we could factor
deeper.
Perhaps this could be yet another option?
some preleminary data (on my machine at home):
Total P-1 test = 91
Stage 1 factor = 2
Stage 2 factor = 1
So on my machine the stage 1 gcd saved me 2 stage 2, so about 2 hour of cpu,
but at the cost of about 90 * 230 sec of stage 1 gcd = 20700sec or 5:45
hours. Seems to me that we could save a little bit by forgoing stage 1 gcd.
regards,
David Campeau
