P-1 coordination thread - discussion

Humm,

I forgot about that in the calc's I guess that throws everything out the window from above.

Still using my MPX as a home machine, dual 2.4G Bartons and 2G of ram, sieve exclusively. Yup it's getting old. I should have sold it off 6 months ago. I could have got ~$400 for just the board and processors . But it's tough to find something decent with u320 or PCI-X slots.

Since this thread is a little old what is the sieving depth and factor value should be used when doing a range?
Thanks.

I wouldn't use sieve depth and factor worth.
I'd simply specify the B1 and B2 values.

Since it will be a while until we get to 14M I would suggest you use.

B1=100k to 120k with a b2=b1x12 to b2=b1x14 depending on how much memory you have.

in other words,

minimum
B1=100000 b2=1200000

maximum
B1=120000 b2=1700000

What CPU memory and amount of memory do you have?

[glennpat]

The one I will run on is an Intel dual core 6600 running 2.4 GHz (stock) with 2 Gig of memory. SOB Sieve will also be running on it.

To use the B1 B2 do I use the AdvanceFactor command for PRIME95? I assume I edit the the worktodo.ini to use the B1 B2.

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.
