It seemed that our comet of prime counts on the top-5000 is now on teh way dow. We peaked at 662 a few weeks back, but with some massive submissions from other...

The challenge is to get more PCs sign up for gfn, which is the only systematic attack that has a chance to upset gimps. Well, wrong forum I guess. This is not...
Since we lost Kimmo, the non-client-server ranges have been going a little slowly, and as the server's pool is about to empty I thought that I'd extend it...

... If you find the known ones, then I'm happy to put it down to an unfortunate statistical anomaly it is then. Blame some French guy! Presently I think that...
... If you really expect 8, then the probability that you actually get less than 2 is, according to that french guy, (1+8)*exp(-8)=0.3% which smells a bit...
... The expectation might have been a bit less. Total range tested from pool 753823 Total tested candidates in pool 238979 # primes found so far 72 => Range...
... But if there are 20 machines in the project, the probability of at least one of them falling in this trap is near 1 - (.997)^20 = 6% and if 100 chunks of...
I just noticed that in the last 2 hours my server died with some kind of SIGPIPE or similar. As it communicates only with you clients via pipes, I was...
The x86 FPU is unique with its 64 bits of precision, and is the only architecture capable of accurately testing the larger candidates in each range, which are...
I know I initially warned everyone that PIES was a finite project, due to the fact that Dan Bernstein's FFT library topped out at 8192 limbs. All those months,...
As a non-PIE-eater, I'm not sure if a comment is valid. ... Sounds to me like seriously good prospective news for PIE-eaters. When Phil said, some time ago, to...
Woh! magic keyboard presses cause bizarre browser behavior... ... All comments are valid. There are no stupid comments there are only stupid people, m'kay. ......
... Darn, I'd hoped (for my sake) it was the other way around. So Phil, make it simple for me. What do I do--just keep on keeping-on until my client fails to...

As readers may have observed, there may be a problem in applying rigorous marketing criteria, when both the CEO and also her technical advisor believe that a...
Also almost certainly known as first Apple PSP. There are some numbers b=2^x*3^y such that Phi(2^s*3^t, b) is 2-PSP. Phi(98304,4096) may well be such a beast....
So the observation is that Phi(3,-2^(3*2^(2^(2^2)))) is 2-PRP ? It sure looks like a good candidate to be a base-2 pseudoprime. It would be an amazing curio if...
