And look what's happened already...
Congratulations! Our records indicate that a computer registered by you has found a unique Arithmetic Progression of primes of length 20. This computer is assigned to the AP27 project. Since primes found in this subproject are not large enough to report to the Top 5000 Primes List, your AP20 sequence is visible immediately.

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Well done Jeff .... and welcome to the competition
Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
11:20 update - nearly two days in.
UBT still in 14th place but now out of 99
So highest AP found so far goes to meddy with an AP23, most AP20-27s found goes to Damien (double checks not counted)

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Actually, we've been moving pretty much in lock-step at maybe 260,000 points difference over much of the duration. It's uncanny!
I have my mad scientist hat on though, so hope to get some more pace going. Mind you, looks like it might be a stretch too far for us to re-capture #14.
Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Checking on it further, so we are. I thought since you'd closed up a few places you must have been getting through more tasks than me. I shall leave the CPUs off the project for nowDamien Healy wrote: ↑Tue Sep 24, 2019 1:59 pmActually, we've been moving pretty much in lock-step at maybe 260,000 points difference over much of the duration.

I don't think we're going to get 14th back (but always up for a challenge) I don't know who shot past all of us but MIXI were 1.6 million ahead yesterday and are now 1.8 million ahead so we're not closing the gap.

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
I managed to pick some up, but only on one machine. The others are only receiving GPU tasks. Bit strange.
You've actually got some CPU tasks from AP27?
Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
I haven't tried yet, I assumed they'd be a lot lower credits than the GPU so I was leaving it unless Damien got too closeUBT - Timbo wrote: ↑Tue Sep 24, 2019 3:04 pmHi Mark

I've only had GPU tasks, even though my PG Prefs were updated to allow both CPU and GPU tasks to download.

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Yep, looks like a good 5x+ advantage for a 1080Ti vs a modern intel 8-core to complete units. Each CPU thread (with hyperthreading) is looking to run 18-24h or so. Not sure on CPU points vs GPU points because I haven't actually finished a CPU unit yet ... !I haven't tried yet, I assumed they'd be a lot lower credits than the GPU so I was leaving it unless Damien got too close

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Hi Damien,
I think they're the same points as the GPU, it's just the extended time that makes them less worthwhile ... although 'only' 5 times as long is a lot better than most CPU/GPU comparisons.

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
The CPU claws its way back a bit by crunching so many units in parallel. But, still relatively inefficient ... a single WU comparison looks closer to 80x

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
AP-20s are quite common (but still great!), then they become much more rare as you head upwards.
Based on Mark's last update, our team has only found two AP-23s for instance. Meddy & Rimmer found those ones.

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Depends if you're actively looking for them or not.
Before this challenge I'd found four AP20s in eleven years, I've now found another twenty five in the past four days!
They get much rarer as the length increases, PrimeGrid previously hadn't found any AP27 (however, Robish found the only known one a day or so back), the last AP26 was a year ago and there's only been four AP25s found so far this competition.

I must concur - eventually I've been "allowed" to have some CPU tasks - and the estimated "remaining time" wih 2.7% completed so far, is approx 2 days.
My GPU takes approx 40 mins... so the scaling factor is about 72 times slower !!
(2 days = 2880 mins / 40 mins = 72).
GPU tasks I've uploaded to date have earned 4,043 credits each...so, I doubt these CPU tasks are going to add significantly to my overall total credits on this Challenge...and in fact with this Challenge ending tomorrow at noon, these tasks probably won't add anything to my total as they won't finish in time.

Tim
Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Into the final 24 hours:
UBT back into 14th place! A nice increase of daily output yesterday (hello Chris), up from our normal ~1,200 tasks/day to ~1,700 tasks/day.
Rechenkraft not too far away either
That Damien is getting a bit close!
Chris C joining in, straight into third place for the team and also an AP23 to join Meddy and Dave.
We're building up quite a collection of APs found

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Yeeehaa! It's been a good chase ... and many UBT team credits on the road!!
We could take a couple more places I hope, with the team keeping at it and Chris crunching hard for the last 15 hours or so. I see the credit all counts right up to 11 UTC tomorrow and won't require validation before then, so ~23 hours more action available!

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Hopefully I'll be able to hold out for another day
All good for the team and the project though. If Chris carries on at that rate it should mean an extra couple of million over what we would have got. I can see Rechenkraft probably falling but I think the power Cows might be a step too far. I'd like to be proved wrong though
It's nice to have two satisfying sprints in a row, hopefully the Formula Boinc one being announced tomorrow will also be enjoyable.

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Hi all
FYI: I've not given up on the PG Challenge...but I have disallowed network access until tonights Sprint* is announced as I've been bunkering some CPU projects as PG wasn't giving me many.
Once the announcement is made and depending on which project is chosen, then I may re-allow network access...it just depends on whether PG needs my credits more than the FB Sprint project does
*The Sprint starts at 10pm BST tomorrow, while the PG Challenge ends at 12 noon BST...and I can't selectively upgrade some tasks and not others
regards

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
There's no way of telling, it's a random number generated by Sebastein that picks a project and then he/project owners manually accept it or not.Damien Healy wrote: ↑Wed Sep 25, 2019 2:23 pm Any wise (or wild) guesses on the Formula sprint target?

Choices left are:
Acoustics@home
Asteroids@home
BURP
Citizen Science Grid
Collatz Conjecture
Cosmology@home
DENIS@Home
DHEP
Enigma@home
LHC@home 1.0
ODLK
ODLK1
Rosetta@home
Universe@Home
VGTU@home
Wanless Mersenne +2
XANSONS for COD
Yafu
Yoyo@home
It won't be Acoustics, DENIS, DHEP, VGTU or Xansons as they're dead projects.
It won't be BURP as it has no work.
It won't be Citizen Science as they only export stats every couple of days or so.
It shouldn't be LHC as that's almost only virtual box and people would complain (although it did get chosen last year ... and people DID complain )
It shouldn't be Wanless as that's only Linux and people would complain.
Most of the others were used last year so could be chosen.
So:
Asteroids@home
Collatz Conjecture
Cosmology@home
Enigma@home
ODLK
ODLK1
Rosetta@home
Universe@Home
Yafu
Yoyo@home
Statistically it should be a CPU project as there's only Collatz left as pure GPU.
As I haven't been bunkering anything yet and I'm only going to be able to start once I get home tonight, I'm planning on leaving my GPUs on PrimeGrid and just bunkering CPU tasks once I know what it is (no speculative bunkers)
Mark
Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
At least you'll have more chance of picking the right project than you have of winning the lottery ... less rewarding though.

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Hi Mark
Actually, Asteroids supports GPUs very nicely - and uses just 0.01 of a CPU per task, so you can run 100% of your CPUs and run Asteroids too.
In fact, Asteroids is the GPU project I'm bunkering and have been for the last three Sprints, though two Sprints didn't happen.
The other CPU project I've been bunkering is ODLK1, (aka latinsquares) whicj uses just about 1Mb of RAM for each task...making it very suitable if you use the PC for other (non-BOINC) work.
regards
Tim
Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Ah, now that's useful. I can also block the IP at the router / gateway level rather than directly in windows. I can therefore keep hammering PG while bunkering a CPU Formula project. If it does end up being asteroids and that supports GPUs, then that would be trickier.Woodles wrote: ↑Wed Sep 25, 2019 2:25 pm viewtopic.php?f=93&t=6400

Hey Mark, Damien,.. Tim, et al
It will be interesting to see if Dutch Power Cows and Rechenkraft.net up their game now; especially Rechenkraft as I'm pretty sure they have the GPU firepower.

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Final result barring any later discovered invalid tasks:
The Czechs and Sici were always going to take the top two places.
TAAT pass Germany in the last hour.
EVGA managed to hold on to their slender lead but UBT were closing fast
Homefarm comes from nowhere and steals top spot.
Fourteen team members is a good turn out for the challenge, I don't know if all of them were aware they were competing though

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
I wonder if the stats might change some more.
Homefarm has delivered almost 10m, but then our team total didn’t jump up by that much?
Unless they were in our team total before but not in the user stats? Maybe that makes more sense as there seemed to be more team credits than we were producing on a user stat basis.
In any case, happy with #11. Feeling good about that

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
In fact, adding up the user stats you posted would put us very very close to EVGA / #10 ...
Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
I was wondering about Homefarm. They only (re)joined UBT in the last day but had work credited from way back.
Does PrimeGrid have a GDPR policy that they've only just agreed to so they were 'hidden' until now?

It’s rather curious isn’t it!

This is very strange...
According to ubtstats website:
1) Homefarm joined UBT on 26th Sept at 12:02 (or at least that's when the stats picked him/her up).
http://www.ubtstats.co.uk/ubt/ubt_membe ... &sz=2&rp=0
2) According to this, they've not "earned" nigh on 10m credits recently...
http://www.ubtstats.co.uk/ubt/UBT.php?c ... =PrimeGrid
In fact they've earned 117,247 recently.
3) The actual individuals totals don't seem to add up to the total team total...
Team total: 28,446,156 (as per PG website: http://www.primegrid.com/challenge/2019 ... teams.html)
Individuals total: 38,375,156 (as per PG website: http://www.primegrid.com/challenge/2019 ... users.html)
In fact, if you add up the 2nd-14th place member totals, (and exclude Homefarm) that comes to 28,398,032 which is much closer to the Team total.
So, I'm wondering what's happening and how/why this "result" can be valid.

Tim

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
He (Richard according to his website) wasn't listed on Johns when I tried to check just before the finish but he was listed on the PrimeGrid website so I assume he 'joined' between 11 and noon.UBT - Timbo wrote: ↑Thu Sep 26, 2019 1:17 pmHi Mark,

I think what's probably happened is that Homefarm have been crunching for a while but their credits haven't been linked to UBT and now that they are, PG has calculated their contribution as being the total now minus what it was on the 21st without allowing for the fact that they weren't in UBT to then.UBT - Timbo wrote: ↑Thu Sep 26, 2019 1:17 pm 3) The actual individuals totals don't seem to add up to the total team total...

As all the other team members have been in UBT for the complete duration then their totals match. If you allow for Homefarm generating 48k credits while they were a member of UBT then it's correct. The difference is exactly 12 tasks.
Individual stats are wrong but the actual team total has been worked out correctly from the returned workunits and not from summing the overall member scores.
I shall edit the final tables to show the correct results
Mark
Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Corrected table due to PrimeGrid not realising Homefarm had only just joined UBT.
Damien does in fact come out as top UBT cruncher for the competition

I think it's a genuine mistake by PrimeGrid rather than any malicious intent

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Just out of interest, what are everyone's totals for discoveries on PG?
Discoveries Primes (0/1), APs (72/164)

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Mine is - Discoveries Primes (2/4), APs (67/188)
My first prime discovered entered the top 5,000 at position 1,334 and has since fallen out (it was early 2011!), the second one never even made it to begin with
One that I double checked entered the top 5,000 at 2,236 and is still at 2,579 now (early 2019) The others never entered.
I've never found or checked better than an AP22
(If you click on the users name to get to their profile then their primes and APs are accessible there)

Mark, well you have done better than I who hasn't even *found a major Prime yet.
Although its probably because I was running the larger GNFR tasks; your less likely to find one, but if you do you know its going to be a large one and your going to get a good ranking.
Well done finding an AP23 Tim, Mark was just saying he has yet to find one.

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Hi Chris,
According to PrimeGrid they were both found using "Proth Prime Search" as were two that I was the checker for. The other two I checked were from "Generalized Fermat Prime Search" and "Sophie Germain Prime Search"
I'm guessing "Sophie Germain Prime Search" is Sophie Germain (LLR), "Generalized Fermat Prime Search" is one of the Genefer ones (but no idea which one) and "Proth Prime Search" is PPS (LLR) or maybe PPSE (LLR)?
I can't remember myself and that's all the information the site gives, sorry.
I still have 50 tasks pending so I haven't given up hope of an AP23 yet

Re: PrimeGrid's 2019 Challenge Series Oktoberfest Challenge
Okay thanks..
Yeah PG is not very good at explaining exactly which Prime got found or rather which task type was ran to find it.
