Reserving k=[B]3677878
[/B]I´m not sure how deep I´ll go, atm I have 2,5-3 hrs/test.

For now I´ll take it. Change of prime for 2M-5M is 80%.

You might want to recheck that:

Expected number of primes: 0.82
Chance of prime: 56%

This is on a quick sieve to P=10M, which left 103048 candidates remaining for n=2M-5M. The sieve depth won't affect the calculation.

Using the odds of prime spreadsheet you have to divide it up into multiple pieces and add them all together when the n-range is large. I divided it up into six n=500K pieces.

I just don't want you to get your hopes up too high since this is a huge effort.

For now I´m taking it, it "only" runs 2 hrs/canidate.
I spoke with reb about it, when he runs dry with long work for srbase he might used this sequence for further testing.
Oh, and 0,82 expected primes are not 80% of prime. Yep, looks like I´m really good in math. *sarcasm*

R3 tested to n=175k (150-175k) (6-10G)

555 primes found, 4360 remain in this range

Rebirther is taken this reservation.
I gave him the sieve file.

My results are attached, notice: The timing is a little jumpy bcs of high cpu usage. :)

Reserving R3 to n=5M (2-5M) (k=3677878) for BOINC

As a result of possible missed primes by srbsieve, I'm going to rerun all remaining k's for R3 for n=1 to n=25000 - I know Rogue believe that n=10000 is enough, but just to be sure I'm going to test all remaining k's again for n=1 to n=25000 (even those not initially tested by srbsieve, since it want take much longer)

I'm going to do it this way:

Sieve all k's for n=1 to n=25000 using srsieve
Test all k/n pairs, using PFGW 3.8.3 (Using ABC $a*3^$b-1 // {number_primes,$b,1} as header)
Report whatever I find

Take care :smile:

I'm gonna cancel this one. All k's has been doublechecked to n=1000, nothing missed has been found. Since the problem with srbsieve and missing primes, when using srbsieve, revolves around the resume function of srbsieve, I expect no primes to have been missed on R3, since all ranges were either done using the old starting bases script or sbsieve version that was prior to implementation of resume function. So basically I'm not gonna spend the next 28 weeks on testing and doublechecking all k's for n<=25000, just to find out that nothing has been missed - IMO my ressourcers are better spend on more precious first time checking (like getting sr16 done) :smile:

Merry christmas and happy new year everyone.

As I stated, I would expect any missing primes to be for n < 10,000. Once it reaches n=10,000, there are not enough remaining k to break into subphases.
