FactorOverride
I do not see FactorOverride in the latest Prime95. How do I use Prime95 to trial factor an exponent beyond the default bit depth? Thanks.

To TF beyond the default depth, you can add a Factor line to worktodo.txt manually. The format is:
[CODE]Factor=exponent,how_far_factored,how_far_to_factor_to[/CODE] e.g. [CODE]Factor=43112609,68,70[/CODE] To do this, first stop and close Prime95, then edit the worktodo.txt file, then start Prime95 again. I don't know of a way to make all numbers, current and future, be TFd farther than the default automatically (i.e. what FactorOverride did). |
There are two other, possibly more effective ways of making sure your currently-favoite exponent gets a relatively deep TF before you LL test it:
1) Buy a GPU, and run mfaktc or possibly mfakto (See tHardware forum, GPU subforum). GPUs substantially outperform CPU (by 10x to 100x) on TF work. 2) Ask me to do the TF in thie fora here or by PM. I've done it twice for user Davieddy. I can usually start in 48 hours or less.:smile: In all cases, enjoy yourself. |
