P-1 coordination thread - discussion

[Joe O]

To specify the desired B1 and B2 values, place the following line(s) in your worktodo.ini file:
Pminus1=10223,2,14000237,1,120000,1700000
where
Pminus1=k,2,n,1,B1,B2

Do not use the AdvanceFactor command, that is for something else.

Thank You! I now see that was in the instructions at the top of the reserve thread.

The 1st few line of my are worktodo are:

Pminus1=21181,2,14000180,1,120000,1700000
Pminus1=10223,2,14000237,1,120000,1700000
Pminus1=21181,2,14000252,1,120000,1700000
Pminus1=10223,2,14000261,1,120000,1700000
Pminus1=55459,2,14000278,1,120000,1700000

It is running.

That looks good to me.

Let us know what your times are per run, it would be interesting to see.

The last two stage 1 times were 6800 and 6893 seconds.
The last two stage 2 times were 5078 and 5119 seconds.

In my range, 14000000 to 14010000, I have 444 numbers left to do. With the one core I can do about 7 per day. From the user stats it has:

"Factors next to enter (main) 'active window' " which is at n=13813352".

From the link http://www.seventeenorbust.com/sieve/next.txt it has:

k n
24737 13629607

Which number do I have to stay ahead of? Looks like I may have to spread the work around on some of my other boxes.

Yes you might have to spread the wealth to several cpu/cores to stay ahead. The number fluctuate back and forth from the highest to some lower k and n. Mainly because somebody dropped it and went back to the first pass queue. If you stay ahead of the "next to enter" you'll be fine. At the current rate 2 or 3 cpu/core should be enough to stay ahead until you figured out the system/p1'ing.

On my pd945 3.4 oc'd to 3.9 I get 5767 secs on stage 1 and the other core is 5484 on stage 2. I am using 840mb per core since I have 2gb of memory. 1.34% probability of finding a factor.

That's funny, I only count 216 k n pairs in that interval. See Attached.

My data was in my file twice. I must of ran makewtd twice. I just experimented with it and it appends the data if ran again. The one you attached has a few for 19249 which I don't have and believe I don't need.

Thanks for finding this!!!

Woops. It's mine that has the 19249 which I shouldn't have.
