PrimeGrid's 2018 Challenge Series Solar Eclipse 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 ;-)

Just got one of these!

Dear Primefinder,

Congratulations! Our records indicate that a computer registered by you has found a unique prime number. This computer is running BOINC, is attached to the PrimeGrid project, and is assigned to the Proth Prime Search. What makes this prime unique is that it's large enough to enter the Top 5000 List in Chris Caldwell's The Largest Known Primes Database.

Since you have auto-reporting selected, the following prime was submitted on your behalf:

Added 125538 : 807*2^2625044+1 (790220 digits)

This prime was found on this workunit which will automatically show as a prime result after verification by the Largest Known Primes Database.

If you have any questions or concerns, please contact us and we will surely resolve any problems.

Once again, congratulations on your find! Thank you for participating in PrimeGrid.

PrimeGrid staff
Mike

Well done Mike.

I'm pretty sure no one on the Team has done this recently...but I could be wrong...


Edit: Two members have achieved this but some time ago:

UBT - bobuk in 2011

and NaRyan in 2009

Hi Mike

Big OOOPS !! I hadn't read the end date correctly and just assumed it was a Sprint and ending on a Sunday !!

Posting now corrected above.

And I've re-enabled PrimeGrid on my PCs...hence why our hourly credits were lower, as they stopped getting new PG tasks about 8pm last night . Not sure if the 6 hours of crunching that's left is enough for us to overtake any other team.

The deficit is as follows:

Code: Select all

19	GPU Users Group		373323.44
20	Canada			355394.91

21	UK BOINC Team		347412.15

22	Noobs Of Kryta [NOOB]	327692.33
23	Alien Prime Cult	319362.22
We're about about 8,000 credits behind Canada - or 50 tasks (@160 credits per task). With the 36 cores at my disposal, that should be easy to make up :whistle: We need another 18,000 to re-take 19th place. :oops:

Code: Select all

Posn.	Team			Credits
19	GPU Users Group		378780.79

The gaps have now increased to 10,000 and 28,000 :-(

So, keep on crunching until 18:00 UTC (or 7pm BST in old money !!)

Hi all

As of 4pm UTC:

Code: Select all

Posn.	Team			Credits
19	GPU Users Group		396594.85

21	UK BOINC Team		365993.42

Gaps now 12,000 and 31,000 and just 2 hours left.

I've added about 11,000 credits since I saw Mikees post earlier, but it might not be enough to help grab at least 20th place.

But you never know.

Looks like we fell short of 20th place by about 11,406 credits (equivalent to about 71 tasks, or about 4 hours of crunching from 36 cores :-( )

And 31,568 short of 19th place - which is about 200 tasks, or about 12 hours of crunching from the same 36 cores - which is more relevant as my PCs weren't crunching PrimeGrid for about 18 hours.

Next time I'll pay more attention to the ending time - promise !!
