1945*2^407283-1 is prime

gd_barnes 2009-01-25 19:48

I have tried to submit a prime 3 times in the last 15 mins. and I keep getting a very strange "Parser error" message at the top-5000 site. I don't know what is going on. I've double-checked myself twice now.

Has anyone else had any problems submitting primes lately?

I've sent an Email to Prof. Caldwell about the problem. Perhaps they are in the middle of working on something to prevent that guy from constantly submitting composites.


Gary

MyDogBuster 2009-01-25 19:50

I submitted one an hour ago and had no problems at all.

IronBits 2009-01-25 20:15

I can't submit my two new primes :cry:

i had problems about 9-GMT at that point no primes had been submitted for 7 hours
15 mins later it worked and someone else had submitted three primes just before me
the username and password box refused to come up
i even tried another computer

Yep, I was able to get mine to submit just now:

Also:

Prof. Caldwell responded that he was working on some code to "plug a hole that the recent vandal exposed by submitting trash". So that explains the issue.

Previously found and submitted primes not shown in this thread:

Beyond: 1817*2^396648-1 is prime

Bok: 1409*2^408568-1 is confirmed prime

There are several new primes for Petey, PCZ, Fozzie, vaughan, and Bok not submitted yet on the top-5000 site. PCZ reports his own primes and I think Ironbtis was instructed by Bok to report his primes so I'll follow up with Petey, Fozzie, and vaughan after I get a bite to eat. :-)

Oops, I goofed. David, you had already reported to top-5000 the prime that I thought still needed to for Bok. I had listed it under your name in our drive thread but have now changed it to Bok.

Brian, the prime that I thought you still had to submit turned out to be a confirmed prime but...you just found a new prime in the last hour. I sent you a PM.

Gary

gd_barnes 2009-01-27 08:24

In correspondance with vaughan, he already has a top-5000 prover account from other projects. He requested instructions on creating a proof code and submitting his 2 primes. I just now sent him the instructions.

These are the only 2 unsubmitted new primes left from the rally.


Gary

gd_barnes 2009-01-27 08:57

This will balance every prime found for this project in this thread as of midnight AZ time, i.e. ~2 hours ago, with the exception of vaughan's 2 primes as per the above post:

Found by PCZ:
1743*2^416002-1 is confirmed prime
1521*2^416257-1 is confirmed prime

Found by JeffGilchrist:
1755*2^416185-1 is confirmed prime

Follow-up and checking is now nearing completion for the rally on the following:
1. Emails for primes sent.
2. Primes in results files.
3. Primes listed daily on David's web page.
4. Primes shown in this thread.
5. Primes listed in post 1 of the 8th drive thread.
6. Primes submitted at top-5000.

No problems found! Nice work on the automated Email and prime listing process David and Dave! :smile: :flex:

Whew, I can actually get back to verifying efforts and updating web-pages for CRUS!

gd_barnes 2009-01-27 09:52

We had a quick turn-around on vaughan submitting his primes. For the record, vaughan found:

Having a prime such as this at the top of the known-primes list is by no means uncommon. After all, they're listed in sequential order, and we're processing them in sequential order on the server, so as long as the list is kept up to date often enough then most confirmed primes probably will indeed be at the top of the list at the time they're found. :smile:

Okay, I've updated and checked everything and the only one that wasn't reported everywhere it's supposed to be is the following:

1791*2^433299-1

It's listed on the Drive #8 as a known-but-not-yet-refound prime, and was returned a few days ago to IB8000 by PCZ, though it has not yet been reported to this thread. Since it's only a confirmed prime, I'll go ahead and mark it down in the drive thread right now. (PCZ, since this prime is already in the top-5000 you don't have to worry about it now that I've marked it down.)

Seeing a confirmed prime and a new prime only 1 k and n=~1000 apart makes one appreciate the filling in of holes that we are doing. For instance, I see that k=1501-1503, 1507, 1511, 1515-1517, 1521-1529, 1533, and 1539 have (supposedly) been previously searched for n=350K-500K yet k=1505, 1509, 1513, 1519, 1531, 1535, and 1537 had not been previously searched at all for n>50K.

This kind of makes one wonder what people are thinking. Wouldn't it be easier just to search them all? Oh well, more new primes for us followed by nice cleanly searched ranges. :smile:

Gary i was also wondering how these ranges were tested in the past.
Confirmed primes and new primes so close together shouldn't be happening if folks had tested the ranges previously.

As to taking a larger range to test, yes i would like to do that.
The half k nibbles i have done already were just a test of my server and procedures.
I am assuming what i returned to you was in order ?.

BTW
If i manually return results, do the pairs and primes get recorded in the team/individual stats.

Unfortunately, not at this time. We've discussed the possibility of including manual results in the database a couple of times, but it's never come to fruition due to logistical problems.

However, yes, eventually we would like to get something set up to keep track of stats for manual results. When we do, it will probably be retroactive so past results such as your here will be included.

Yes, what you returned to me for results works.

Most of the ranges in this area were tested by k-value instead of n-value. As far as I can tell, for the k's that were searched, all primes were found up to the point at which they stopped testing. Most people on other projects do not search all k-values within a large range like we do. That's why I had a confirmed prime for k=1531 but a new prime for k=1533 so close together. k=1531 had been previously searched for n=350K-500K whereas k=1533 had not been searched for n>50K. Although a couple of individuals such as Benson (for k=1003-1400) were doing it, NPLB's approach to testing huge k-ranges all at once was new for projects in the prime-searching community when we started the project. Now PrimeGrid is doing it also. That's no surprise. As an extremely well-run and organized effort, PrimeGrid picked up on the extreme efficiency gains in searching large k-ranges at once.

As Max said, no, manual ranges are not included in our stats. But if you'd still like a range, just let me know what size and we'll send it to you.

Along the lines of ranges, at this point, I would consider the 5th and 6th drives higher priority than the 8th drive. I'm going to post some manual files for all drives that need them here shortly. Although there will be less primes because of the higher n-ranges, the average top-5000 score per CPU day will be higher on the 5th/6th/7th drives due to almost no previously known primes and a deeper sieve depth.
