It appears Kimmo has just encountered something that Raffi encountered a while back - the dreaded pseudoprime! Phi(2^s*3^t, 2^a*3^b) is very often a 2-SPRP and...
... Indeed. Here is a small titanic example Calling Brillhart-Lehmer-Selfridge with factored part 33.94% Phi(2^7*3^2,2^3*3^4) is prime! (1.7337s+0.0434s) David...
This 6,320,430 digit prime was found on Nov 17th. I like the article Chris wrote. Among others, he mentioned both gfn and phi. I hope we can pull more...
George Woltman, via the massive array of machines called GIMPS has just found (and verified, he's always very strict about not announcing until an independent...
... The last 6 points on http://primes.utm.edu/gifs/lg_lg_Mn.gif are in fair accord with the Wagstaff slope: 2^exp(-Euler) Like Phil, I wrote a happy message...
Cool our chef has found the second prime in the c/s arena. I wouldnt call it huge but it certainly signals the right direction. Go go! Bo PS: just dont want it...
PS: The Wagstaff cumulant line is shown in http://opteron.mersenneforum.org/png/log2_log2_Mn.png There was an unlucky glitch between M31 and M32, but ...
Unless we want to shuffle the order, we wont get to the 100000 digit area in another 6 months. Or if we can attract more folks. I am interested in testing...
I've just noticed from http://primes.utm.edu/primes/status.php?hours=18 that the windows (boo hiss!) guys are churning out primes at a rate of knots, with...
... Perhaps, but I have not sually been lucky. I am happy plodding along. ... "Not I" says Chris, returning to the video game that has wasted many hours of...
Somewhere we should see the longer term plan of the project. The available ranges should be done in less than a year even with no new computers added. A...
... I've worked out why I thought George had been lucky - his CPU power growth is greater than Moore's law. Assuming expenential growth of CPU power along the...
... One thing that annoys me about that chart (and the one on the prime pages) is the fact that it's actually meaningless. The only more sensible way of...
... 10^(100000/16384) = 1269157.8 We've handed out numbers up to 1229522 already, and we've only been going a week. I think we'll have a 100000 digit prime...
... Ok, I calculated the number at 1270000 but in my mind, I read it as 1700000. :( [...] ... [excause my ignorcence, a couple of weeks from now, I will talk...
... GeneFer, with a 3x slowdown, can test 50 times the range of Proth at the same exponent. I can't explain why I only get <1.1x the range. ... All the general...
Hi everyone, I've just brought a new server on-line which has limited awareness of the architectures of the various machines being used. The reservation/status...
... Indeed. It was time for another one - one every ~10000 (3300 tests) is more or less the expected density. ... That would be nice, and probabilities are in...
... Yup, the explanation has been added with a quick server restart just now. The restart cleared the stats, as they're ephemeral (not remembered, only...
Congratulations to Juraj for his first ever find, particularly on such a modest machine too! Juraj - as you're new to the big prime arena, I'll perform the...
Juraj has kindly compiled a very fast Alpha client using Compaq's CCC. It's available from the clients page http://fatphil.org/maths/PIES/clients.html using...
What is the best way to get the libcpml.so (Alpha math library) installed on a debian host so we can use this binary? Can anyone point me to it? Thanks, James ...
