Re: Mersenne: mprime startup at boot-time

Sorry, -d, not -m. I'm not that familiar with the command line arguments of mprime. My expertise lies in the symantics of Linux. One way to pipe to a virtual terminal AND to a file is by using a combination of a tee and a redirect. Something like: /usr/src/mprime -d | tee -a

Re: Mersenne: Alot of small exponents for double checking will be reassigned tonight and the following days

1999-10-24 Thread Floris Looyesteyn
If you want small exponents you better try to get them tonight and the following days cause a lot of them are going be released again tonight... I skimmed through the assigned exponents list and counted about 20 exponents that are (almost) overdue... So be there when you want them... I

Re: Mersenne: difference between LL and double check

1999-10-24 Thread Robert van der Peijl
Paul van Grieken asked on 21 Oct 1999 at 17:16 h Why is there a difference in iteration time between the LL test and a double test. For the same FFT-size, the double checking code has to perform a bit extra work per iteration: it multiplies by 2 before the DWT, and divides by 4 afterward.
