Mersenne: scientific american

2001-07-21 Thread Spike Jones

There is an article this in the new Scientific American on distributed
computing, but no mention of GIMPS.  I feel cheated.  spike

Mersenne: Factorisation

2001-07-21 Thread Daran

What is the probability of a successful trial factorisation in the range of
exponants currently being given out (16-17M)?

Are the estimates given by the program for p-1 factorisation accurate?

Regards

Daran G.

I've been going backwards for so long I stopped looking.  :-)

I recently built a new Duron 800 system (OCed to 943MHz) to replace my old
K5/133, so hopefully I'm going forward now.

My most recent personal milestone was to pass 1 P90 year on DCs - not much,
I know.  I was annoyed that I fell just a few percent short when I turned in
my previous result, and would have had to wait five months to turn in the
next if I hadn't upgraded.  The new machine runs fifteen to twenty times as
fast, so I should double that in a couple of months or so.

Russ that IS an impressive milestone!  I've only been processing 9 days but
we all have to start somewhere.  Tell you what, check out

61&m=3680928671&p=1.  We are looking for some "founding fathers".  It'd be
like getting a second wind.

Mersenne: Hosting site for mersenne utilities?

2001-07-21 Thread Gareth Randall


I'm intending to release a small package of utilities that I have written which relate 
to the mprime program.

I could host it at my ISP, but ISP accounts have their disadvantages, and I would 
prefer to have an independent account with a URL that won't change in the near future.

Is there a well-known "semi-official" repository for such programs, or would anyone 
like to start one?

Maybe someone has an FTP server which is going to be around for a long time that they 
can offer an account on?

Yours,

=== Gareth Randall ===
