do I have to worry about this warning:
WARNING: --pmin=500000000000000 from command line overrides pmin=10000000000000 from `321comb5M-25M_55TE1.txt'
I stopped computing till I have an answer. |

This is fine. It's just letting you know that you're starting at 500T instead of the 10T that's in the sieve file header. Basically, you're overriding the header and starting at 500T for your 500T-501T range.

I'll finish my task but it can take more than a month, my computer in't running 24/7 and the speed is: 714679 p/sec, is there a deadline? |

None that i know of. Other ranges have been reserved for more than a month, so don't worry!

I see that at the top of the post that we are using version 1.7.12, but when you follow the link to the software, it shows a newer version. Which version is recomended?

Use ver. 1.8.2

I only have 3% completed, my computer is to slow and most of the time not running..
I can send the factors I found (2) but I am going to stop.
I'll go back to llrnet.
That's perfectly fine. Just upload what you've done so far and I'm sure someone else will pick it up.

John, this warning can be avoided by removing the "Sieved to ..." entry from the sieve file. You can also add comment lines beginning with a `#' character to the file and they will be ignored by sr2sieve, which could be used to keep that information without causing the warning. e.g.
# Sieved to ...
ABCD ...
instead of
ABCD ... // Sieved to ...

Thanks Geoff! Lennart has made the change. :)

Yes you can. Just stop it and make change in command file and copy sieve file. Then start.

Don't see the speed improvement with the new version on my machines. They're all running some version of Redhat Enterprise Linux |

Sorry, I should qualify the improvement is against v1.6.20 which was being used by BOINC. If you were using v1.7.12 which is what we started out with in this thread, you were already seeing the speed increase. PG has recently updated the BOINC versions to v1.8.2.

Aaahhhh, I see. I only detected a 1% speed up, which was about the reduction of the sieve file.
Thanks for the quick answer!
BTW: 380T - 385T is done. |

I´ve read, that you grant credits for manual sieving.
Where will I see, what you´ve granted for my manual working ???

There's no specific place to see this. You'll only notice it as a bump in your normal daily production. Additionally, manual credit may take between 2 weeks and 4 months before it is awarded.

You say it is manual; is there any posibility to inform the siever, which sieving-range gets which credits? Perhaps, can you send your granting to the manual siver via privat news too and not only to the server(-stats) ?

There's probably a fixed Cr / T ratio, I guess. On a second thought, with each new sieve file a T is cruched faster. So the work per T is not constant. I think I better stop guessing and let John answer this one ;) |

Without going into any details, yes, for the sieves we attempt to award a fixed credit per T completed. While not exact, it is comparable to PPS and PSP sieves in BOINC. As Puzzle-Peter pointed out, this gets adjusted when new sieve files come out.
Manual sieving and Project Staging work initially did not offer cobblestones for manual work. However, as time permits, we do our best to award all manual work. But this is an inexact process that sometimes can take up to 4-6 months.
We do not intend at this time to send out notices when manual cobblestones are awarded. We encourage anyone who is concerned with cobblestones to please do only BOINC work...as this guarantees the proper awarding of credit.
However, we are especially grateful for any manual work done. Without your help, preparing new projects for PrimeGrid would be an overwhelming task.
Thank you!

713T-714T completed,
72 factors, 6,525 sec/factor
Q6600 @ 2.40GHz
Does anybody know where I find p/sec or how I calculate it?

What's the difference between 321comb5M-25M_230TE0 and the _55T that we were using?

321comb5M-25M_230TE0 In this one all numbers up to 230T is searched.
and all factors removed up to 230T
321comb5M-25M_55T In this only all up to 55T is removed from sievefile.
The higher "T" done smaller sievefile and less candidates left.

We are far beyond the first goal of 1000T, but I think sieving still removes candidates 10 times faster than LLRing, maybe even more. Plus every LLR test is done twice. So our optimal sieve depth might be 5P or something?

Quick question here, if you download the latest sieve file each time, does that make it faster or anything or does it help at all and if so how? If it only helps once we start with the prime finding then I can understand that but I'm curious of it otherwise :) Thanks
Edit: Lastly is there a way in the archive where you can add a line like the line you put in for the new sieve file where you can say manual credit granted so we don't need to ask, that would be very easy and helpful.

A new sieve file is released when enough factors have been removed to make a small speed improvement in sieving. Early in a sieve, it makes sense to update the file often as many factors are being removed relative to the total. However, later in a sieve, this number reduces quickly and therefore, less updates to the sieve file.
In short, yes, the latest sieve file (which is a smaller sieve file) is faster.
Edit: Lastly is there a way in the archive where you can add a line like the line you put in for the new sieve file where you can say manual credit granted so we don't need to ask, that would be very easy and helpful.
This can be done but it would be meaningless. Credit is not granted in one lump sum on a single day. Once ranges have been moved to the archive thread, credit is awarded. However, it is distributed averaged out over a period of time based on your RAC. Therefore, some users get their credit in a couple of days while others take weeks.

Soon we will have done twice the initial goal of 1000T. Priorities have changed towards PPSE and there is the new Primorial Sieving. We're slowing down at 321.
Is there any specific sieve depth we want to reach at a certain point in time?
Regards, Peter

321 manual sieve is at a good point to enter BOINC. When time permits, the transition will be made.
While we still have a long ways to go, at p=2P, we are almost 2.5 times deeper than the n<5M sieve...so we have an excellent start to the n>5M search...which by the way is getting very close due to the Ox Challenge. :)
