Hi, Perhaps I'm just the last to notice, but www.primeform.net/openpfgw is back! The content hasn't changed, but at least the domain works. :-) Greg...
The window is quite big enough :-) I think I've found a good form for this, just started PRPing... Unfortunately I don't have enough spare wetware time to...
... DB's claimed "entropic" primes, which, as I pointed out at the time, are not incompressible despite his claims. (And that is compression to strictly less ...
Can any of the low-level bit twiddlers tell me how well the common programs (Proth/PRP/PFGW/AthGFNSv/NewPGen) would behave on the 2GHz Intel Celeron, which is...
Well, one of the main factors will surely be the L1/L2 cache sizes. The Celeron has a 128kb L2 cache, compared to 512kb for the P4 and 256kb for the Athlon...
... I think Phil and Paul pretty much described this. My comment is that the sieves would do very favorably, and the FFT based proving and PRP programs would...
... I can comment on PRP/PFGW which use the same gwlibs as GIMPS does. Your results will vary depending on the FFT size. If your numbers are small and fit in...
... As I recall, I was careful to say that http://groups.yahoo.com/group/primenumbers/files/ME/maxent.txt was merely "high-entropy". As Phil has said, and now...
... I interpreted 'max' as maximum. I interpret 'maximum' as that which cannot be exceded. Simple {ped,sem}antics, perhaps akin to the difference between a...

Hi, Am I missing something, or did that still require 19761 factor/prp tests? (Or is there a non-custom built sieve which lets you go faster, or some other...
... Guess what... It is far too easy to forget how slow doing things with such large numbers is. Getting 25 digit factors out of 30000 digit numbers is...
Michael: I was indeed worried when you pre-announced that your 3*25+25 effort might need such a 25/30k final ECM. I was careful to avoid that in the...
... I'm too deep into anti-war activity to try (and presumably fail!) to do a ECM+KP rival job, right now. Please continue Michael, but be advised that Jens is...

Hi, Well done Jens! By now I have been stupid twice, my program was in fact calculating the headroom incorrectly, so my supposedly safe bet actually needed...
\\ In Pari-GP, Jens's prime is simply obtained by m1=2^26917; m2=3^16982; N=10158*(m1*m2)^2-1+2*m2*lift(1/Mod(m2,m1)); write(jens,N); \\ and then do: pfgw -tc...
Paul, The NewPGen format did not work in current network2 mode. ONLY the first file piece would have worked (I tested it here at work). HOWEVER, since this...
Hi Jim, ... Correct, my subsequent testing showed that that was the case - I assume that the NewPGen format line was sent and the client PFGW treated it as...
... Nope, it is pretty minimal. It simply "walks through" a file, cutting off lines of work, and sending them to a client when it requests work. It knows ...
Jens successfully posted his prime with Chris: http://primes.utm.edu/~caldwell/primes/page.php?id=64207 and claimed the small prize, which turns out to be a...
I have been working for about a week and a half with a new system, and finally got it to produce this screen output. PFGW Version 20030423.x86_Dev (Alpha...
... The SSE2 has been working for a while AFAIK. The real thing shown above is the "x86_Dev". It does not say "Win_Dev". The x86 dev is a Linux build. It...
