This is the official 30 day warning.
We will be shutting down the 321 sieve on October 21st, 2020. On that day the work generator will be shut down.
Get your 321-sieve badges while you can!

That's just semantics.
We (almost) never shut something down with the expectation that it will start back up again later. If it's worth running, we keep running it.
When we shut something down, it's because there's no need to run it anymore. So, in that sense, you could think of this as permanent. From a user's perspective, you *should* think of it as permanent. If you have a credit goal you want to reach, or a badge, you should get it before October 21st. Don't plan on seeing 321 Sieve ever again.
That being said, sieves are like zombies. Or villains in horror movies. You think they're dead, but they keep coming back for more. What happens is that the underlying project (321-LLR in this case) may eventually run short on candidates. This current sieve is for candidates up to n=50M. I can't even begin to guess when we'll run out of 321 candidates to test, but it will be many years from now. But if PrimeGrid still exists then, we'll have to fire up the 321 sieve once more to sieve from n=50m to n=75M. When we restart a sieve, this is why. We expect this sieving to last for a long, long time. Just not forever.

Is there a chance we will run out of tasks before the 30 days is up? |

No. The work generator can run nearly forever. |

If you could run out of tasks before the 30 days were up, what would be the point of giving you a 30 day warning?

Not in the immediate future, although this is still under discussion.
We will need to restart the CW sieve at some point. The problem with that, however, is that the GPU software is very old, only works on Nvidia, and will undoubtedly require some work before we can use it again.
There was some discussion last year about sieving ESP/PSP/SoB from 50M to 100M, but we won't need that for a while, and we need to evaluate whether or not (and how) to do P-1 factoring on those numbers. So that's not a simple decision either.
So nothing in the immediate future, but maybe one or two sieves at some point.

LOL!!! I was just wondering because I don't want to keep people from getting a badge just because I can get a bigger one, I am at a new badge today and am happy with it but will keep going as long as everyone can get tasks. |

Hopefully not before too long - the CW sieve and TRP sieve are the only two badges that I have left stuck in "bronze". Gotta get that nice, matching shiny set, after all! :) |

Hi how are you?
I was just checking I'm halfway to Jade here so may stay long enough to get the Sapphire badge too, since the post saying we had 30 days came on the 21st and in 3 days I've gotten 1.5 million credits to get my Turquoise badge plus another 2.5 million towards the Jade badge. |

All good thanks.
I'm doing over 250k per day, so should reach Ruby in a few days. But then it's a 3 million jump to Turqoise, which I should also make. But the 5 million to Jade after that could be an issue. So, to give myself a better chance I've just fired up my son's second laptop for an extra 8 cores - although it's only running 7 right now, for some reason.

No, 321-LLR will continue for the foreseeable future (many years). The reason we're stopping the sieve is discussed here. Basically, switching to the new LLR2 app has sped up the LLR process so much that we don't need any more sieving (at least, for a long while). |

Well after 321 SV ends there'll be no more CPU-only sieves.
Good time to concentrate on prime-finding what with LLR2 and others!

Maybe when us youngsters are at a retirement home, we'll start up 321 sieve for 50M-100M. |

Yes! I hope to live to see at least two of the Sierpinski projects end :P
Assuming avg age for males as 83 yrs old, I have..... around 70 years left to finish the conjectures!

I had a pc crash and can't get it running again, I even put the harddrive in another pc to at least abort the tasks but even that won't work for me, I'm still trying but some of my wingmen, 108 tasks in progress, will be waiting for them to expire so the next guy can crunch them......SORRY!!! |

Unfortunately, there’s always going to be someone that needs “just one more day”, no matter what day we decide to stop. We’re already running the project beyond when it should have been shut down to give people some extra time.
You could try borrowing some computers, renting some inexpensive cloud servers, etc.

Maybe sieve this side subproject after? As stream wrote in that thread, the project will be stopped because tests are getting very slow with n > 10M. Also it's non-BOINC, so sieving would be outside BOINC as well, I guess.
What would need sieving in the near future are factorial or primorial primes on PRPNet. Still not BOINC though, but at least it generates credits for PSA badge, if you're interested in those.

DigitalOcean has a promo and where they will give you $100 in credit and which is good for 60 days. You can easily fire off eight to ten instances which should help you dramatically in making up the residual credit you need.
Out of curiosity, how much credit do you expect to fall short of? |

Not to be off-topic, but the side project is still BOINC-based.
Yes, like many others I do want a replacement for 321sv, whether it's C/W or anything else. But I assume the dev team is very busy rn what with implementing LLR2 and protecting the server.

You are putting out about 116k in credit for 321 Sieve per day which means you will be hitting 5.04 million by Oct 21st and which is just fine and assuming no hiccups.
Also remember that you effectively have four extra days past the deadline since you are allowed such a queue and in spite of the fact that the server at the end of Oct 21st will shut off the generation of new wok units. Add a few stragglers here and there requiring a double checker and you can easily squeeze out another couple of days.
I would feel fairly comfortable if I were in your position. |

You probably need a referral code to get the discount. If anyone needs, just ask. Lots of people can provide one.

Now that is a case where bunkering would be useful.
I'm heading for Gold, and assuming 10k per day (my current output), I would not make it by Oct.21st, but I should be able to with a bunker of 4 days.

That's not bunkering.
Having a cache doesn't mean you're bunkering.
Bunkering is the practice of explicitly not returning tasks after they're completed, for whatever reason. There's no reason to do that here.

Yes, like many others I do want a replacement for 321sv, whether it's C/W or anything else. But I assume the dev team is very busy rn what with implementing LLR2 and protecting the server. I thought it wasn't so much the time required, but more that currently there's no need due to them being sieved to very high n?
And out of curiosity, why do some people want a sieving subproject? To me it feels just like preparation that is very useful and sensible, but less fun, because you can never find a prime. Just composites.
To go completely off-topic, you can check mersenneforum for some interesting projects that require sieving.

Hi. Thanks for the feedback. I'm not sure if I have the acumen to "go virtual"; it might be too difficult to do at the last minute. I'll look though.
I calculated I needed about 5 days worth.

Thanks again for the feedback, one point made caused me to think. I've been running without a cache (to be good citizen) for so long I forgot it was there. I've undone that and now I think I should have enough work units. Sorry for the disturbance. |

Hey mikey
I see from the 'subproject status' page that you have the oldest unfinished workunit. What's interesting is that I'm partly to blame! I was a wingman, but unfortunately that host was off for a few days, and when it came back on, it aborted that unstarted unit because of being passed deadline. However, the next person to download it 'Timed out - no response'.
I guess you'll eventually get the credit... :)
PS I got my Turquoise today! Not sure if I will make Jade.

CONGRATULATIONS on Turquoise!!! I hope you make it to Jade.
LOL it's okay!! I've already stopped crunching these wu's as I've already gotten my Sapphire badge and can't get the next one. Technically MAYBE I could have gotten the next one but then I would pass my Teammate by waaaay too far for him to ever make it up and he would change Teams and I don't want that. It's a choice I make at several Projects where I have actively crunching Teammates in front of me, I'm #1 on my Team at most Projects already, so another one here or there is pointless. It's not important in the big scheme of things anyway, if my computers are still crunching and they reopen 321Sieve at some point I will crunch for them again and maybe get my next badge then, there are lots ofther Projects that need crunching time too!! |

Don't be short as there are no 'make-up days', better to have too many than not enough. The Project said they have PLENTY of workunits to give us they are just taking too long in the scheme of things. |

So do I!
I need about 5-6 days to get there. I don't know what time on 21 Oct the work will be shut down. But I can probably cache enough to get my Jade.
I'm assuming that, although work generation will be stopping, the rest of the processing will continue, so that we will get credit for WUs that we complete.

Well the original post came at 18:14 UTC so for those still trying I hope not.
I know there has to be an end but I do hope all those close can get there!! |

I'm assuming that, although work generation will be stopping, the rest of the processing will continue, so that we will get credit for WUs that we complete.
Correct.
Thank you!
My situation has just become harder as my laptop host has had to be suspended as it's going to be used in video projections from today.

I've just done some calculations. I need about 2100 WUs to get Jade. With caching I can do it, even without the laptop I've had to suspend from today.
So I'm a happy chappy. :)

Will the work generator be shut down on 00:00UTC Oct.21st or 18:14UTC?

Strictly guessing I would say midnite of the 21st, so 24:00 since it's not like they are running out of units they could send out, but only an Admin can say for sure. Midnite would give the max chance for everyone still trying to get badges to get them and not have someone miss by 3 hours. Let everyone make their max effort and if it works great if not well you sure tried hard and it's not the Projects fault you didn't make it. |

The sieve is almost at 95P, so instead of arbitrarily stopping the sieve tomorrow (or today, actually, depending on where you are), we're going to set it to stop at exactly 95P. That should give you a little extra time. Maybe an extra day or two.

Just learning... what is a P number. (i.e. what does 95P mean) |

P == Peta, or 10^15. So 95P = 95,000,000,000,000,000
Sieving works by using "small" primes to divide the big numbers and easily and rapidly remove any that are composite. When we say we've "sieved to 95P", we mean we've removed all candidates that are divisible by any prime numbers smaller than 95,000,000,000,000,000.

I just checked - I need 249 credits to my Jade. Not even one full WU :)
Edit: And now that I've posted, I see I've got it!

thanks. I guess I guess that but wasn't sure.
So, wouldn't 100P be a better limit, given it seems easier to remember?
Cheers. |

It's oversieved anyway. 95P deemed the next clean stopping point. Zero left top send out as of 21:15UT. |

I am eagerly waiting for the challenge to finish so that download restrictions can be lifted. I am stuck with a zero queue and have been like that since the start of the challenge.
I need 117 units to hit 102,500,000 (actually ever so slightly above that). I suspect there will be lots of work timing out from others who have hoarded work units and assuming I can build a small queue. (Too much ado about nothing at my end) |

So did it just stop as of a couple minutes ago?
Because my computer has no tasks going.
Is it finished?

https://www.primegrid.com/stats_321_sieve.php
Right now there are 0 waiting to be sent, 32.3k in progress and falling as results are returned. If you get new WUs at this point, I believe it would be from time-outs, invalids, or aborts. |

So what the next default subproject is planned?
PPS-SV
If I understood it correctly, PPS-SV should now be the default project, if a user (in PrimeGrid Preferences) checks "Use CPU" but does not check any CPU subproject.
If this is so, then the explanation text (in the link above):
"You must also select CPU apps below.
If you do not, 321-Sieve will be automatically selected for you.
Enforced by version 6.10+"
should be changed accordingly.

Humm,
321-Sieve
Recent average CPU time: 1:17:46
PPS-Sieve
Recent average CPU time: 16:55:30
Will PPS-Sieve really be the default CPU project ?

I am wondering about that too, PPS-SV should not be the default. Probably something else new will be.

Thanks, it's fixed.
PPS-Sieve is the new default CPU app.

Oh, BTW, 321 Sieve (321-Sieve) still shows up as a selectable sub-project for crunching in PrimeGrid preferences.
I guess it could be removed from there.

I'm leaving it selectable until the last task is done.
There's probably some people desperately hoping to get just ... one ... more ... resent ... task for a badge.

Many thanks for helping us out! I just processed my last desired unit. :-)

After all can you say how many workunits between 16M and 25M became unneeded?
