We're expected to find a twin prime before 20G, and it looks like we got one already :smile:

There should be one prime every 5-6M, on average.

That has to be false. IOne prime every 4G would result in 5 primes to 20G.
You mean 4-5M right?

Yes, I meant 4-5M. Bad typo :sad:

biwema 2006-05-14 23:36

You can expect a prime every 5M.

After sieving to 35T you will find on average a twin every 2430 primes or every 13.5G (means the chance of miss = 1/e in that range)

pacionet 2006-05-24 07:34

It seems to me that (in our first results) that there is 1 prime every 8-9 M rather than every 4-5M. Do you agree ? This change the probability of finding a twin ?

MooooMoo 2006-05-25 03:32

[QUOTE=pacionet]It seems to me that (in our first results) that there is 1 prime every 8-9 M rather than every 4-5M. Do you agree ? This change the probability of finding a twin ?[/QUOTE]
I think the average prime density is still 1 prime every 4-5M. So far, there have been 17 primes discovered, and a total of 76M has been marked as complete. 76/17 = 4.47M per prime, which is about right.

We may have reserved all ranges less than 200M, but many of them are still in progress, meaning more primes may be found.

No the -1 is not prime

victor 2006-06-14 13:55

Ok :)
And why do you check for +1 first?

pacionet 2006-06-14 14:45

What is the actual ratio PRIMES / MILLIONS TESTED ?

Citrix 2006-06-14 15:52

[QUOTE=victor]Ok :)

Does it make any difference, which I check first.

victor 2006-06-14 16:07

[QUOTE=Citrix]Does it make any difference, which I check first.[/QUOTE]
Not at all, in fact I don't care. It was only for information.

Citrix 2006-06-14 16:54

I have an LLRnet server set up for +1 numbers, so I prefer working on +1 numbers. If I wanted to do -1 search, I will have to modify all my computers, which will be a hassle. Hence, I tested +1 primes.

pacionet 2006-06-15 07:10

Ok I computed actual ratio: it should be 47 primes on 255 Millions tested, that is

0.184313

It means we are finding a prime every 5.42 Millions.

We are slightly under previsions (between 0.2 and 0.25) .

biwema 2006-06-15 09:43

Where The number of twins remains constant (After sieving to 83T, a range of 24.7G and 10005865 Candidates it is one twin every 13.77G), the average Gap between Primes is increasing proportiona to the ratio of the log(sieving limit).
That means sieving to 45 bit instead if 44 bit means a 45/44 larger gap between the primes. (Reason: The sieve is biased to finding twins)

The current value at 83T is a prime every 5.83M.

In order to not leave the question open-ended, I'm reporting that all the primes I've found are already reported in this thread.

I reported some primes in a previous post, before I completed my range, so I felt the need to clarify.

I got the same residues, when dobbelchecking on the exact same machine, so I'm only reporting 7 primes. Anyone has any idea how that is possible to do the same test twice and get two different results?

paulunderwood 2006-11-14 16:43

Errors could be for a number of reasons:

* Faulty LLR code -- extremely unlikely
* Overclocking too much.
* Incompatable computer components
* computer components not set properly
* faulty components such as bad RAM -- check with memtest86
* bad operating sytem -- maybe with virii
* hacker altering results

But are we sure that we have not lost any primes in this range ? (for example a prime could have an erroneous residue (different from zero) on your PC ).

[QUOTE=pacionet;91506]But are we sure that we have not lost any primes in this range ? (for example a prime could have an erroneous residue (different from zero) on your PC ).[/QUOTE]

I'm not sure, but when all come to all, the computer is not showing any mistakes in the BOINC projects it is running, like PrimeGrid forinstance, so the problem must be with LLR... I'm not sure, but if I don't get an invalid result from PrimeGrid then I have a hard time to see ow it possibely can have something to do with my computer:sick: And also if anyone wants to double check, feel free to do so, actually maybe we should ask rytis to do so, then to see if we get different results again... but why should i have been hacked? I havent downloaded any files, and I've reacently cleaned my computer for spyware...

Maybe we should PrimeGrid to Check the entire K space, first from k=1 to k=25 G, then there will be done doublechecks of the entire k space, and errors will be found emidiately :) So what is your oppinion about that?

Regards!

thommy 2006-11-15 09:53

there is not that much point in double checking, as the tests only last very few longer if k increases. and the possibility for a test to be prime is the same in all ranges. so just test untested ranges...
