A new milestone has just been reached; as of today, the #3-20 projects combined have a normalized score that's higher than SOB's.

Neat. But SOB's next prime will roughly double their score, yes? Or is that project dormant these days?

Thanks for the observation.

And we are back to 1000 primes!

Code:

Username: RPS (entry created on 10/30/2005)
Database id: 819 (entry last modified on 07/11/2011)
Active primes: on current list: 1000, rank by number 2
Total primes: number ever on any list: 3011
Production score: for current list 49.8906, (normalized: 3610),
                  total 50.0742, rank by score 4
Largest prime: 59*2^3408416-1 ‏(‎1026038 digits) via code L426  on 04/09/2010
Most recent: 1155*2^1082878-1  ‏(‎325982 digits) via code L1828 on 08/14/2011

Our current score is 49.9889 and we are getting closer and closer to 50.0.
I did a little estimate of what kind of prime(s) we would need to reach this goal:

It turns out that just one prime for n=2291723 would be sufficient.
Or equivalently two primes for n=1828630, three primes for n=1602489, ..., or just ten primes for n=1083017.

So, with the 7th and 8th (and 10th) drives and perhaps a little help from the 2nd megabit drive we could reach score 50.0 quite soon.

BTW.: By concentrating on just the 11th drive we would need an equivalent of 33 primes (of about n=735k).

Thomas11 · 2011-10-13, 14:24

Our current score is now at 49.9976(0877).

For a spot-on landing at score 50.0000 we would need a prime in the interval n=1382646-1401606 (assuming k<10000). Unfortunately my tests for the 2nd megabit drive are already beyond this range.

But nevertheless there is still a chance for a 2 megabit + 1 sub-megabit combo...

Kosmaj · 2011-10-14, 10:16

CONGRATS to all! We are there: 1094 primes, score = 50.0003

Kosmaj · 2011-10-15, 02:38

Here is our current status at Top-5000

Code:

Largest prime: 	59*2^3408416 - 1 ‏(‎1026038 digits) via code L426 on 04/09/2010

Primegrid has finally surpassed SOB today.

Code:

Rank    Project      Primes     Score      Normalized score
 1       GIMPS         13      55.8432       1353458
 2       Primegrid    1960     51.4985       17562
 3       SOB           11      51.3943       15824
 4       RPS          1136     50.0662       4193

RPS could take third place in a few years if SOB doesn't find any primes between now and then...

Didn't no where to post this but did RPS ever reached a normalized score of 51 points? RPS has now 50.9996.

Kosmaj · 2014-02-02, 02:29

Hi Carlos,

Here is the thread for milestones!

As you can see we reached 50 more than 2 years ago, in October 2011.
Just a few more primes and we'll reach 51!

pinhodecarlos · 2014-02-02, 13:30

Kosmaj,

In fact my question was stupid because the score is normalized. This happens when you are sleepy and try to post things at 11 pm after a day of 39 ºC. In fact this temperature has been constant for the last 2 weeks. In the news they are saying that this Summer in Rio de Janeiro is the worst of the last 30 years. Usually the Rio 40 (40 ºC) happens in December for 10 days but it has been in this situation of an average of 35 ºC since last two weeks of December until now.

So after we reach 51 we have a race to 52. Good news. I'll do everything to reach that mark for the next 4 years (during my PhD, during my access to computers lab).
Also, there's a fight going on between me and my wife, she doesn't let me buy a new computer...suggestions? Kill her? lol....The reason is that our PhD scholarship is too low for leaving in the city of Rio de Janeiro but because I don't have exclusivity with the university I can get a part-time job (at weekends) to earn a little extra money. I am going to do that to buy a new machine.

Carlos
