Anyone who has the GIMPS bug understands what this'll do to them. Checking System Information, it says there is 32 MB Adapter RAM. It wouldn't be so bad if my times majorly improved when my monitor shuts down... But I don't think this is the problem because I had reasonable response for several months (it took a while to realize that the PIII1000 times on the benchmark page was for 133 speed RAM and that I have 100 speed and that I had to change what I thought was reasonable responese ;( ) - then it stopped - about the time I did a Windows Update. Checking Task Manager shows Prime95 getting 99% CPU, but a EXPLORER.EXE process keeps jumping up to get 1% which is activity I don't remember from before. - ----- Original Message ----- From: "Jud McCranie" To: "Carleton Garrison" Cc: Sent: Saturday, November 10, 2001 7:32 PM Subject: Re: Mersenne: timings > At 06:47 PM 11/10/2001 -0500, Carleton Garrison wrote: > >I have a Dell Inspiron 8000 with a ATI Mobility M4 which I'm pretty sure is > >PCI. > > As George and I found out, the problem is when the video card is sharing > your main RAM.

Steve, The output from the script is interesting, but it can be very misleading for those of us who have recently upgraded equipment. The P90 hours per day listed on the web site is just total P90 hours divided by total days since setting up the account. For instance, I am listed at around 324 P90 hours per day, and my Pentium 4 by itself is close to twice that.

I don't know exactly how my friend Rob Reid did it, but he has managed to create a whole stats thingamabob... It gives us a 7 day rolling average and tells you which team has passed who and how much work they've done... Even though most of the stats are geared towards our team, the top 100 lists cover all of the top 100 teams... You can check it out at: http://www.teamprimerib.com/rrxsp/ The only thing I'd point out is the stats rely on the PrimeNet lists, which sometimes lag a bit, so if you need pinpoint accuracy, to the minute, these stats aren't for you... :) Rob does a stats pull once a day... Our other stats page is done by a frequent contributer to this list, Carleton Garrison... It is geared to expressing our stats graphically... It only covers our team, but it is very interesting nonetheless... http://www.teamprimerib.com/dcesp/ Good luck! _________________________________________________________________________ Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ Date: Sun, 11 Nov 2001 20:12:21 -0500 From: Nathan Russell Subject: Re: Mersenne: 1st 6 P90CPU yrs jump!

It was computed on a machine that can no longer even be purchased new in some stores, on a version of the program well before the present version. The lengths that ran quickly on George's P-90 may have nothing at all in common with the ones that run quickly on your P4. Personally, on another note, my own P3-600 is half a dozen times slower than the fastest machines now, as opposed to one or two tens of percent slower when I bought it. I'm debating how to upgrade, but I don't even know if I *could* short of replacing the processor, motherboard and most likely memory. Also, it occurs to me that while the P4 is fastest (by a factor of a little under 2) for GIMPS, the various K7 class machines are fastest for just about every other task (and GIMPS is not the only project to which I donate time). I'm almost thinking my best bet might be to wait another year, until dual-Athlon motherboards are more commonly available, but then I read about the issues with speed reductions when both processors are running LL testing... It's going to be a tough decision, and I just thought i'd mention this here rather than start another thread, as long as we were talking about timings... Nathan P.S. I run win2k pro, with 384 MB of PC100 memory (actually, 256 is PC133 but I have yet to check if the MB would support that if I removed the other 128) and I don't know what other stats are relevant. _________________________________________________________________________ Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ Date: Mon, 12 Nov 2001 03:37:15 -0000 From: "Daran" Subject: Mersenne: Fw: The Mersenne Newsletter, issue #18 - ----- Original Message ----- From: "primenetnewsletter" To: "Mersenne Newsletter" Sent: Wednesday, November 07, 2001 8:49 PM Subject: The Mersenne Newsletter, issue #18 > * Over 70,000 double-checks completed. > * Over 100,000 exponents tested for the first time!

Would it be possible to add a "CPU Type" column to the Individual Account Report? Since v21.4 it seems even more important that each and every machine has the correct CPU type selected. Since a lot of members that have been around a while (myself included) have probably upgraded many of the machines participating, this would allow a quick check to ensure that each machine is in fact running the optimum code.

Seems to imply that about 40% more first tests are being completed than double checks. If so then the gap between exponents assigned for first tests and exponents assigned for double-checking will continue to grow. Personally I think the cut-off point may be a bit on the low side. If a "typical" DC assignment on a particular system takes less than ten days then IMHO the system concerned should be running first tests. That criterion puts the cut-off point somewhere around 600 MHz. But, as many people have pointed out in the past, what does it matter if people want to run first tests on "slow" systems? The work still gets done in the end!
