Maximum prime for sieving
Sorry, couldn't find a suitable thread for this.
If I was to use gfndsieve to sieve a range of potential candidates, does anyone have any rules of thumb as to when it is best to stop sieving and start running pfgw? Presumably more sieving would be advantageous for large values of n where pfgw would take longer, so a larger -P value would quicken the overall time by reducing the number of candidates. |

What’s your factor elimination rate? What Is your testing rate on your last candidate of the sieve file when running pfgw?

 Put the number of working threads into the formula, sa you can launch as many pfgw programs as you have cores from the respective directories. |
