Re: Mersenne: Re: Mersenne Digest V1 #895
It's actually a Microsoft program and is one of their kernel toys package. http://www.microsoft.com/windows95/downloads/contents/wutoys/w95kerneltoy/ I'll answer to the group as well since this is a very useful tool for prime95 users. It allows you to spot processes that go into busy waits and the like which waste CPU time. Try holding the mouse button down on the desktop - went to 100% CPU on my Win95 system, but I haven't used that in over a year now!

Mersenne: 3 years
Hey everybody! Yesterday (friday 26th) it was three years since I joined the search! It's been fun! My team is Account IDLL P90* Exponents Fact.P90 Exponents P90 CPU CPU yrs LL Tested CPU yrs* w/ Factor hrs/day -- ---- - --- Team_LiTH 122.875 492 4.112 381013.12 and right now we are at place 70 in the top producers! We are using 25 machines of all types. K6-2, Athlon, PI, PII, PIII. I recently retired my old 486. It was doing one factorisation every 3-4 months or so... Now me and another teammember will go out and celebrate :) I just wanted to say KEEP UP THE FUN WORK! :) Regards, /Lars Feeder of FPU's Lindley _ Unsubscribe list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers

On Windows XP ctrl-alt-del shows that information (maybe on Win 2000 too). However, WinTop puts blanks for zero percentages whereas ctrl-alt-del on WinXP shows 00.

Mersenne: number of processors participating
L.S., I read a message some time ago on this list that claimed that the number of processors had gone down by about 9000. I don't have stats on this other than the actual available from the status pages. Does anyone have stats over the last year, like numer of pc's and/or processor types, processor speeds? If there would really have been a decrease in participating processors, (I don't think so) an updated graph of Primenet throughput would show by now, is there any update in the pipeline? I went through the status.txt file to see if the new 'stress test' button could have played a significant role, I don't think so. By the way if one runs prime95 without a user name the application fills in an S0 as user name. I found 3170 entries with a name '.' (only a dot) The fast majority of these entries seem to be have been abandoned. They have been reserved over a long time with a constant daily flow. Does anyone know more about this?

Linux drivers come with source code, so if there is a bug, any competent programmer can fix it. Also there is almost invariably a mechanism for feeding patches back into the source tree. On the other hand, Windows drivers come wreathed in obscurity, usually clouded even further by licenses which prevent disassembly and therefore effectively make it illegal for anyone other than the original author to post a fixed version. IIRC, Linux drivers that are kernel modules do run in real mode; someone on the list please correct me if I'm wrong. No, they don't run in real mode - which gives access to only the bottom megabyte of memory, in 16-bit mode, i.e. you're using the system as a fast 8086. Win 9x/ME drivers _do_ run in real mode! Some parts of some drivers (in proper 32-bit operating systems like linux, also Windows NT/2K/XP) _need_ to run in ring 0, which does allow unrestricted access to all memory, thus allowing the driver to trample on memory belonging to other processes. Part of the art of writing successful drivers is to do as little as possible in ring 0. This raises the question of why some folks have mentioned that drivers under NT/2K don't cause these sorts of problems They're much less likely to. For a start, it's easier to write ring 0 code than real mode code on a 32-bit system; e.g. there's less room to confuse 16-bit and 32-bit addressing modes. Secondly, as I pointed out above, you can get out of ring 0 to do most of the work, so most of the time you have full protection from the OS to prevent you from clobbering someone else's memory.

Re: Mersenne: Mprime crash
Presumably a badly written Linux driver can cause the same problems as a badly written Windows driver. Yes. There is however a subtle difference. Linux drivers come with source code, so if there is a bug, any competent programmer can fix it. very very few programmers are qualified to debug obscure device driver problems, especially so when the problems involve realtime interactions such as issues with sound driver IRQ latency or whatever. More so since the vast majority of modern PC hardware is undocumented (ever seen the tech ref for a Soundblaster Live, or a Nvidia Geforce chip, or even a late model network controller?) _ Unsubscribe list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
Re: Mersenne: number of processors participating
Henk, I don't have a consistent set of statistics, but I do save the world test status page every few months. So I can tell you that on 2-apr-2001 it showed 38652 machines on 20983 accounts, and right now it shows 30186 machines on 15659 accounts. I'm sure I didn't just happen to catch it at its peak; I recall there being over 21000 accounts at one time. WRT team '.', I recall a few months ago it seemed to be holding up some double-checks at the low end of the assignments, but it did eventually complete them all.

My first guess is that we're beginning to compete with the various commercial projects (of which there are several now, and were none 2 years or so ago). It's hard for me to envision that causing a fifth of the participants to leave, though!
