Re: Mersenne: W2K service installation problems
Hi George, I have tested this new feature (using W2K + prime95 V22.7) I have found that when logging off and logging on again, the small red icon is not coming back (while prime95 is still running) Regards, Jean-Yves - Original Message - From: "George Woltman" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Thursday, July 25, 2002 20:55 Subject: Re: Mersenne: W2K service installation problems > Hi, > > At 09:22 AM 7/25/2002 +0200, Helmut Zeisel wrote: > >I recently upgraded from WinNT to W2K and now want to install > >the service version of mprime again. > > > >Since I previously used ntprime, I tried "ntprime -install". > >This worked, but starting the service exits with > > > >Could not start the Prime Service service on Local Computer. > >Error 5: Access is denied. > > > >I have administrator rights, so this should not be the cause. > > > >Anyway, I downloaded FireDaemon-Light-1_5-BRC1.exe and installed Prime95. > >Starting FiredDaemonService: prime95 now exits with > > > >Could not start the FireDaemon Service: prime 95 service on Local Computer. > >Error 1: Incorrect function. > > > >Any hints what went wrong? > > Not really. > > Please try ftp://mersenne.org/gimps/p95v227.zip > The GUI version can now be installed as an NT service.

Mersenne: AthlonXP
Hello All According to latest benchmarks (http://www.mersenne.org/bench.htm), AthlonXP seems to be slower than the Thunderbird. Does anybody have a technical explanation ? Do we have to consider now Intel/P4 as the best platform (at least for prime95)?

FW: Mersenne: Re: Factoring Failure?
Hello all, I have browsed some logs I archived long time ago and I have found this: In may 1998, one user, "tomfakes", cleared around 80 exponents with factor found = "1" It was in the range 7013000-7055000.

Re: Mersenne: IMPORTANT: BUG IN VERSION PRIME95 17
George, I have plenty of reasons to feel that you should not be so worried with what happened : - Since I joined GIMPS project more than three years ago, you always impressed me with your thorough work. You have proved several times your professionalism, up to the way you announced this bad news, honestly and humbly. - Don't forget your motto : 'just for fun'. A small bug in a program whose primary goal is to entertain all of us is nothing compared with e.g what happens now in Kosovo.. - Even the great Mersenne himself commited two bugs, by incorrectly 'proving' primality of M(67) and M(257). You have been wrong only once... George, the hardest is now behind us, let's discover M38 quickly and everything will be forgotten.
