Windows x64 better for Prime95 ?
Hi,
I'm currently running 2 instances of Prime95 on my new dualcore Pentium D 945. This CPU supports EM64T, but it is currently running a normal (32-bit) Windows XP Home. Would Prime95 benefit...

One thing I would like to add is that laptops (and especially P4's) have a pretty intensive venting set-up, which usually also attracts a lot of dust. In my laptop, it worked fine the first few...

Hmm, I have three little questions.
I think I noticed somewhere that gmp-ecm is slower in stage 1 than Prime95, but gmp-ecm is waaaaay faster in stage 2. Is this correct ?
Does the advantage of...

Oh, IC, but then how do you know that the resulting cofactor is composite ? It seems to me that if you find a factor of a Mersenne number, it always a relatively small number (compared to the...

Little Question
In the lists of not completely factored Mersenne numbers, how do you know that the remaining cofactor is composite ?
So, what I'm asking is actually this : if I were to find a new factor (of the...

Pocket PC
I don't suppose there is a Windows CE (Pocket PC) version of the Prime95 software ?
The reason I ask is because I recently bought one and it seems to have a 400Mhz processor, which would be quite...

I did 35615149 to 60 bits again too a few days ago. I don't know why it stayed behind there so lonely. Maybe something went wrong while sending the results of that range for a moment.

But this rises another question though. These duplicate entries, does this mean that the LL Residues do not match in...

Nope, that sounds about right.
First stage only uses B1 and all factors of k have to be below B1.
Stage two is a little more general and allows for 1 of the factors of k to be above B1, but still...

I recently studied some stuff relating to Rabin-Miller tests and I know that they don't prove a number being prime, but they do prove a number being composite.
So why don't we (before running the...
