[QUOTE=VBCurtis;350441]Lennart-
Do you know what the limits of the software are? Max p-value? If a 3M range is much more efficient than 2M, would a 4M or 5M range be yet more efficient?

Since 6-9M has barely started, it may be wiser to do 6-10M or even 6-12M for greater efficiency. Is there a reason not to run a bigger n-range?

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.

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. [URL]http://home.comcast.net/~jimb_primegrid/ppr9M/[/URL]

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

Well folks, there you go. If they consider just the proth side for "optimal", since the riesel side is not their interest, optimal is around 700P.

Wow.

Here's a question, Riesel Side.

etc

Wouldn't be wise to take these k's from the sieve file? How much speed would be gained? For proth side a few k´s below 300 probably are also done to 4M and 5M.

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. :smile:

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.

I completely forgot you guys don't use a sieve dat file on the GPU sieving.
