It would appear that Dr Caldwell has set up the alias already.

Razor_FX_II 2009-04-22 16:03

I'm in a holding pattern untill I know if I should continue the way I have it "NPLB, Srsieve" or change it to "Srsieve, PrimeSearch"

gd_barnes 2009-04-22 16:06

[quote=Razor_FX_II;170559]Select LLR
I used "NPLB, Srsieve" in the field below and it gives credit to:
Geoffrey Reynolds' srsieve (program)
[URL="http://primes.utm.edu/bios/page.php?id=518"][COLOR=#0066cc]PrimeSearch[/COLOR][/URL] (#518) : PrimeSearch (project)

Correct?

Edit: After gd_barnes posted posted "No!! Not yet" Could somebody please make up my mind which way to have it[/quote]

That is correct. Enter it as "PrimeSearch, srsieve"

I was telling Max, no, not yet on entering NPLB as the project name in a proof code. Continue exactly as I stated in my post.

Guys, you are confusing Razor here. Prof. Caldwell has changed nothing yet or I would have gotten an Email from him to that effect. I also would have made a huge announcement in the news and started changing all of the instructions on entering new proof codes.

Yes, I changed the "Username" on our project to NPLB but the project name in the proof code is still PrimeSearch.

Make sense everyone?

Razor, sorry, this is a huge transition period for us.

PCZ 2009-04-22 16:09

To be safe use PrimeSearch instead of NPLB.
Then submit your prime.

gd_barnes 2009-04-22 16:20

I won't be back on the forum until later tonight.

For anyone who is trying to enter a new proof code:
If it turns out that "PrimeSearch, srsieve" doesn't work, then "NPLB, srsieve" should work.

About 2 hours ago for Zachariassen's prime, I used "PrimeSearch, srsieve" and it worked fine.

Brian (PCZ), you are correct, it does appear that Chris may have set up the alias since "NPLB, srsieve" still picked up the PrimeSearch project. Therefore we may be able to enter it either way, at least for a period of time.

Edit: I just now looked at Razor's proof code L807. It looks good. Now the prime just needs to be submitted. It looks like we have another Brian. :-)

Thanks for the help guys, this should be easier the next time.
I completely understand that things are being changed around at the moment and it figures I have to get right in the middle of it at right at the worst time.
But hey what are guinea pigs for, right? It's all good, anytime you need another alpha guinea pigs tester just let me know. I'm your man.

gd_barnes 2009-04-22 16:44

Thanks the other Brian (Razor). (lol) Yep, right in the middle of the transition period. Everything looks great.

Once it is all set up like that, entering primes is a snap in the future.

I just checked. Did you know that your prime link here is a link to nothing? Actually, it's pretty funny what comes up. Click it and see what you think.

Edit: The same thing with the Srsieve and PrimeSearch links.

Well that exercise wasn't all that bad considering all the primes found in the last 8 hours. Nice run. We hit one of those elusive hot spots in the prime world. According to my book keeping (pencil and paper) we have all primes entered and recorded.

NEXT

On a side note. According to the database, Zachariassen found his prime after testing about 100 pairs. Now that has to be a record for a Top 5000 prime.

Nice job all. :tu:

No

I've found my first prime after 8 test, found the second after 796. For my 3th prime I had to test >25000 pairs. I went from best average to worst in a few months. I'm glad it has evened out a bit so now I have a normal average.

The chances of a prime in port 8000 at the current level are around 1 in 6700 so that is quite normal. I had a recent stretch where I found 1 prime in about 35000-40000 tests on that port. Right after I pulled my machines off of it, a huge run of primes came last night with at least 2 (maybe 3) new searchers finding one. I joked that I cleared out all of the primeless area for others.

I then switched to port 5000 and found a prime within a few hundred tests with a chance worse than 1 in 7000. As MrOzzy found, it all evens out in the long run.

For the mini-drive, the chances are going to be around 1 in 5000-6000 tests.

[quote=Razor_FX_II;170614]1683*2^331994-1 is prime[/quote]

Razor, for port 9000, you don't need to report them here because they are not top-5000 primes. This thread is only for primes with an exponent > 350K (350000). The admins will do it automatically in the 1st post of our 9th drive at [URL]http://www.mersenneforum.org/showthread.php?t=11285[/URL]. Ian (MyDogBuster) is our trusty updater of primes in that post and I think he does it about once per day using a primes file that is created by the server. There are lots of them!

Edit: I see that he has already added your prime there.

I just wanted to make sure that everyone is aware that port 9000, which is used for our 9th drive, is not top-5000 work but it is fast work and you'll find a lot more primes. If you try to submit them at the top 5000 site, it will simply give you a warning message that the prime is too small. As for our stats here, you'll get more pair tests and primes but over the long run, your pair test score and primes score will be roughly the same as if you did larger tests on the other ports.

Gary[/quote]
Regarding everything evening out in the long run: ah, if only it would do that for me! It seems that I'm hitting all the primeless areas and everyone else is picking the primes out from in between them, regardless of what drive I'm running. :smile:

For example, my quad can produce approximately 1000 tests per day at port 8000's current level. That comes out to, on average, one prime in 6.7 days--round that up to 7 to account for the fact that my quad produces a wee bit less than 1000 tests (more like 930-950) per day. I've had it on port 8000 since close to the beginning of this month--more than 3 weeks of constant testing on that port. Yet, I've only pulled out one prime so far! I know these things even out over the long run, but then listen to this: Before that, I had the same quad on IB4000 (which Gary quoted the odds for as "worse than 1 in 7000") for more than 2 months. Based on what I remember being able to crank out on that port, I calculated that (assuming a 1 in 7100 odds of prime) I *should* be able to pop out one prime every 10 days. However, in all of those ~2.5 months I only found one! :smile:

I guess I'm long overdue for a big run of primes by now--hey, these things have got to balance out sometime or other! :smile:

No big deal. You should ask David (IronBits) about his trials and tribulations early in the project trying to figure out where and what primes to show in what threads. He even joked at one point something like: "You just need a thread called David's primes" and "I'll dump them all there". Looking back on it, it was rather comical although I'm sure a little annoying to him at the time.

Look at it this way. It keeps me in work. LOL

I had the same problems as David did when I first started. It took me a week to figure out the difference between a k and an n.

If this is in the wrong thread, feel free to move it.
May I make a suggestion?
Please put the port #### in the title of the thread so I know which thread I should be putting these in.
I still can't make heads or tails out of the thread titles the way they are.[/quote]


Unfortunately, we are reporting primes for 3 ports; IB4000, IB5000, and G4000 in the k<=1001 prime reporting thread. So I suspect it will make the thread title too long.

Hints:
(1) The multiplier or the 1st value in the k/n pair is the k-value.
(2) The exponent or the 2nd value in the k/n pair is the n-value.

Therefore with k=465, this one goes in the other prime-reporting thread that shows k<=1001.

To make it easy, just remember that this thread is ONLY for port 8000. Port 9000 goes nowhere and everything else goes in the k<=1001 thread.

Here is what I think I may do: I'll put the ports in the 1st post of the 2 prime-reporting threads.

Edit: I've now added the port(s) to the top line in the 1st post of each prime-reporting thread.

[quote=gd_barnes;172091]Very good. Our first k=1400-2000 prime for n>600K! That's simply amazing how fast we blew through the n=500K-600K range!![/quote]
Indeed--it's amazing to think that it took us MONTHS to do the same range for the same number of k's in the 1st Drive (k=400-1001)! And this one went by in only a bit more than a month! :w00t:

Congrats on finding NPLB / PrimeSearch's 900th top-5000 prime!

100 more to go for a cool 1000.

In the words of Chris, we now own 18% of the top-5000. :smile:
