Note: The reservation of the last day (35 candidates for 8 clients = 280 pairs) I've checked some minutes before all were done and found nothing. This prime was the last pair of the last client! Noticed first after I've submitted all!

Welcome to NPLB MiHost!

Are you aware that you need to report your prime at the top-5000 site at [URL]http://primes.utm.edu/primes/home.php[/URL] ? For instructions on doing so, see the 1st post of this thread at [URL]http://www.mersenneforum.org/showpost.php?p=123340&postcount=1[/URL].

If you have any questions, feel free to ask. Everyone is very helpful. :smile:

Not to worry, it didn't last long. :smile: The top-5000's verification system quickly found that 705*2^963099 [URL="http://primes.utm.edu/primes/page.php?id=97303&deleted=1"]had small factors[/URL] and deleted it.

Edit: I just noticed something else, though. I see you reported the correct prime under the proof-code L696, "Nicol, Srsieve, NPLB, LLR". A while back we switched to new sieve files that were sieved with the ppsieve/tpsieve programs. You thus need to submit all primes found after that point under a new proof code, which in your case would include "Nicol, Srsieve, Psieve, NPLB, LLR".

I made an announcement about this back when we switched to the new sieve file but you may have missed it since you didn't find any primes around that time. What you'll need to do is [url=http://primes.utm.edu/primes/includes/mail.php]send an email[/url] to Chris Caldwell (the top-5000's maintainer) and ask him to move 705*2^963099-1 to a new proof code crediting "Nicol, Srsieve, Psieve, NPLB, LLR".

AMDave 2011-01-09 23:30

I see that now. Cool. Thanks.
I'll send another email to Dr Caldwell telling him to ignore my spam.:smile:

EDIT: Ok. new prover code added and email sent.

That's not exactly what we want to see here...someone "wondering" whether his machine is stable enough to search for primes. :smile:

Regardless, congrats, David, on a nice big prime.

One more thing: Your proof code did not have NPLB in it. Can you create a new one that has NPLB in it and have Prof. Caldwell move the prime over to it? Thanks.

Just to clarify: driver-related BSODs (as henryzz's turned out to be) have no bearing on the stability of the CPU as it affects prime searches. Assuming his CPU is otherwise stable, there should be no problem.

[QUOTE=henryzz;247205]How long does it usually take him to reply or fix? I messaged him through the website.[/QUOTE]
Usually he responds pretty quickly; he might have missed your note. I'd send him another one. While you're at it, though, you'll want to ask him to fix these other proof codes I just spotted:

-[url=http://primes.utm.edu/bios/code.php?code=L620]L620[/url] (Stevens, NPLB, LLR) should have Srsieve in it as well
-[url=http://primes.utm.edu/bios/code.php?code=L641]L641[/url] (Stevens, Rieselprime, LLR) doesn't have a sieve program in it either--presumably Srsieve?

Not meaning to nitpick--may as well kill two (er, three) birds with one stone. :smile:

I believe the website sends an email to his address, so the end result would be the same. In my experience, I've gotten responses from him pretty quickly using that form too.

What is going on with the 715*2^965837-1 prime ?

Now the prime shows found by Dennis Schreiber and is credited to PrimeGrid. David, can you please check with Prof. Caldwell again?

Keep in mind that you need to create a brand new proof code and request that Prof. Caldwell transfer the prime to it. He will not want to add software or projects to an already existing proof code.

Thank you.

That's what I did. The code was deleted automatically and reassigned to Dennis Schreiber. That prime is now sorted. I suppose I had better sort out the other problems. I hate wasting his time this much. I will be more careful in future.

Looking [url=http://www.noprimeleftbehind.net/stats/index.php?content=prime_list]here[/url] those 5 primes were found on 5 consecutive days: Feb. 11th to 15th.
