PrimeGrid's 2019 Challenge Series Oktoberfest Challenge

This section is where you can post topics related to Challenges from other websites, such as Formula-BOINC, SETI-Germany and BOINCstats, as well as project challenges such as from WCG, PrimeGrid et al.

As a Team, we really want to engage as many team members with these challenges, as this gives us a great way of attracting more members to our Team...plus we get to show our strengths as a Team by (hopefully) doing well in each one.

PS: I have moved lots of topics into this section where they are relevant...as you can see, we've always been happy to take part in Challenges...and long may that continue ;-)

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 :)

In fact, adding up the user stats you posted would put us very very close to EVGA / #10 ...

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!

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 :)

Hi Mark,

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.

regards
Tim

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.

Nope, that's his total that's being counted as all gained today :?

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.
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 :D

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 :)

Just out of interest, what are everyone's totals for discoveries on PG?

Discoveries Primes (0/1), APs (72/164)

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 :D

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.

Primes (2/4), APs (67/188) - Mark
Primes (0/2), APs (19/24) - Tim
Primes (0/1), APs (74/164)) - Chris

Seems I'm last, If you take the Primes as the major sort order :cry:

What specific PG task(s) did you run Mark to find those 2? EG GNFR19

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 :lol:

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.
