Hi,
I was asked this question today. Since I'm not a Linux user, any help
in answering this question is appreciated.
My computer is now dual boot Linux/Windows 95. I have downloaded mprime and
put it in the same folder as prime95 and verified that it runs. How can I
set it up
Hi all,
A quick note about today's new version. There is virtually
no reason to upgrade. The new features are described below. The
biggest change is that network retries will now default to 60 minutes.
The NT services version now supports ECM factoring.

Why can't we do first first the factorization up to n-2 bits (1/4) of
the trial factoring time, then start the P-1 factoring up to 1/3 of the

I don't think this is correct. Look up Dickman's function in Knuth vol 2

Hi all,
I'm working on prime95 version 20. The important new feature
is a P-1 factoring step prior to a Lucas-Lehmer test. The P-1 factoring
step has a 3-5% chance of finding a factor at a cost of 2-4% of an LL test.
The net effect is we speed up GIMPS' throughput by a percent or two
Hi all,
The Mersenne benchmark page is badly out of date. I'm going to

send ONLY VERSION 19 TIMINGS.
Please email to me, NOT THE ENTIRE MAILING LIST, the
following data (if unsure of a value that's OK).

I agree that all machines are contributing to our knowledge of Mersenne
numbers. The gaps will eventually be closed.
Hi all,
Thanks to all that have submitted timings. There are still plenty
of gaps to fill in and having multiple results for each machine is desirable.
My first draft of the benchmark page is at http://www.mersenne.org/bench.htm
Comments are of course welcome.

If you feel up to it, please give the beta of version 20 a try. The QA
group has verified that the FFT code is working, but have not spent much

Thanks to all the beta testers of v20, you found a lot of bugs!!
