One more idea: It may make sense to stop this sieve now, run 6-9M until 300P, and then add 5-6M to the 6-9M sieve and continue with 5-9M up to 800P or more. I thought this should have been done with 2-3M added in to 3-6M from 100P to 150P. -Curtis
I shall check how much we can sieve.

Think about that we sieve for DC !!

We test all proth k's 3<k<10000

We sieve riesel/sierp (+1/-1) 5<k<10000 3M<n<6M. I have todo some tests if we can sieve more but I think some older card can't do that.

We also sieve 6M<n<9M manually now. http://home.comcast.net/~jimb_primegrid/ppr9M/

So if you calculate with DC you will see that we have lot of sieving left before we reach optimum

How much speed would be gained? For proth side a few k´s below 300 probably are also done to 4M and 5M. Carlos Edit: just asking. Last fiddled with by pinhodecarlos on 2013-09-10 at 12:20

We do not use any sievefile. We sieve 5<k<9999 3M<n<6M in a given P range.
It is not faster with a sievefile and lets say you have 2000 computer downloading ~300Mb every month.

Even if we sieved with a sievefile those k you say we should remove will not make any speedincrease anyone would notice.

There are 4998 k's both +1 and -1 so removing those k's will not make any difference.
