BOINC 5.8.17 gives my 400 MHz PII Deschutes a rating of 404 floating point MIPS and 698 integer MIPS. I am currently running SETI@home, Einstein@home and QMC@home on SuSE Linux 10.1, meeting all deadlines. My RACs lowered because of a 15 days vacation. Tullio |

yeah my P2-400 had around 15k credits when i finally shut her down. the great thing was the 512k on die cache...it was a workhorse on seti classic until version 3....when 4hr wu's became 8hr wu's...lol i've got two slot A's, an athlon 700 and 800. i think that was when AMD finally turned around. late next week i'll be shutting down some systems for the summer season. Basically all AMD cpu's: four Duron 1.8's, a 2400XP and a mobile 2400XP overclocked to 2.4ghz plus a P3 1.2, P3 800mhz and a P4 1.6 laptop. my highest gas bill this winter was $21.55. Guess where all the heat came from...lol that is why alot of the farm will be hibernating thru summer. |

Yep, formerly known as the IDT WinChip and Cyrix processors when VIA first bought the line. let me double chk but i may hav a spare asus p5 mb amongst my parts.i got a good collection of vintage k6 units also |

Thought I would dust off an old Compaq Deskpro 4000 I had lying around. It has a screaming Pentium 233 MMX chip with 98SE and 384MB of RAM. Check out these times... 510004303 122115122 1 Apr 2007 17:53:12 UTC 7 Apr 2007 3:17:54 UTC Over Success Done 367,208.00 33.20 33.20 |

That was the hottest chip around when I bought it. Now that I think about it, it was the last Intel cpu I bought before AMD started one-upping Intel in the 'bang for the buck' category. My, but how things have changed. I ran AMD for all those years since, until the core 2 hit the scene. Gonna be an interesting battle in the coming year or so, but I gotta believe that Intel has the upper hand right now, and is not gonna give up 'king of the hill' very easily. And remember what RAM used to cost?? I remember software programs such as 'Ramsaver' that used to try to free up a few mb of ram, cuz software was cheaper than memory.

See http://setiathome.berkeley.edu/result.php?resultid=513719539 my 233 MMX just reported the first result on a WU :-) [EDIT] Get the KWSN MMX optimized app at: With graphics, No graphics.

If setting up some old machines find Simons link to BoincPE. I am going to get another old machine running tonight. Heck with loading an operating system...Too much work for an old machine. Official Abuser of Boinc Buttons... And no good credit hound! |

Well the P4 died...Funny thing is, it was the Power Supply that died so it may once again come to life... Official Abuser of Boinc Buttons... And no good credit hound! |

A lot of those old P2's can be upgraded to 1Ghz (using a 1 Ghz PIII) or 1.4Ghz (using Powerleaps's upgrade). I upgraded my slot 1 400 mhz Celeron to 1.4Ghz using the Powerleap upgrade. I was getting performance out of it close to a 2.8Ghz P4. The system is offline right now but I have been keeping it around for the coming launch of the Haiku OS. I would also love to get a different Slot 1 motherboard for it that supports a bootable CD-ROM. |

Hiyas all... soon as the project comes back up... am going to try my luck adding another system to my 2 running S@H, it is a pII duel 350, running Ubuntu atm...will need an optimized app, mmx type... hope it all works... cya on the boards |

Duel PII's would be cool. That was back in the day when you could run dual processor systems. I sure miss those days. Now these greedy companies lock the processors down so you have to by special high end processors to run them dual. |

Now these greedy companies lock the processors down so you have to by special high end processors to run them dual. I don't know about "greedy". How else are companies supposed to segregate their business products and move the higher end stock? The higher end stock doesn't just cost more because they want to charge more, but because it's been verified and tested to work as intended, and that testing takes manpower which in turn costs money. Those extra costs get handed down to the consumer in the form of higher prices, but you know it's going to work as the manufacturer designed it to. |

One of the rigs I use is a Dual PII 400MHz, 256MB ram that needs to be upped to at least 512 but it works for the moment. it's happily crunching on Rosetta while we wait on FedEx. |

installed last night/this morning 05/09/07... got seti setup, and it only sees 1 cpu... what I gotta do for both cpus to work?? 2 separate boinc directories, how would I go about this in linux(ubuntu)?? am a linux newbie |

I got an old clunker desktop (AMD K6-2 400MHz, 256MB RAM) that's a perfect candidate for the BOINCpe treatment. All that remains is for me to figure out how to configure it ahead of time (Before burning the CD) so I don't have to manually make the system relogin to S@H every time it gets rebooted (Unfortunately I am a newb, and BOINCpe's setup instructions are written in a way that assumes everyone using it is a rocket scientist). |

I am running a dual P-III 750 on an ASUS P2B-DS with a whopping 512 MB as a small internal file server under XP and it is doing quite fine. Though, because of the outage i enabled Rosetta and now it is mowing through the big queue there. But i definately will switch back to SETI when that is cleared up (i hate to leave open strings). My next task for this machine is to make it dual boot and have it running linux by default. Maybe i can squeeze some more cycles out of it :-) |

Here is my Aptiva K6-2 550 running Debian and boinc-app-seti 5.13. There's an interesting story about this one. Debian Etch has prebuilt packages for boinc-client & boinc-manager 5.4.11 and boinc-app-seti 5.13 but when I tried them I only clocked 250 Mfips, about half what I got from the default install on Win 98. Interestingly, the turnaround times were about the same, 5-6 days per wu. After a bit of digging I learned that fftw3 version 3.1.x, which is the Etch version, only supports 3DNow (K6-2's simd instructions) for K7 and up. However, fftw3 3.0.x supports 3DNow on k6-2 & 3, so I got the source for that package from oldstable and rebuilt it with -m3dnow (and -ffast-math and -march=k6-2). I also got the boinc-app-seti source and rebuilt it with the same switches making sure any args to the configure script were set so the code would build correctly for the different configs. I was hopeful about that, but it didn't work, the boinc-app-seti client wouldn't run. Almost at random, I tried rebuilding boinc-client and boinc-manager (from the boinc pkg) and luckily that was the answer. boinc-app-seti's setiathome_enhanced links with boinc-client (I think) and there was some kind of binary incompatibility with the pre-packaged version). That was the answer, and the setiathome_enhanced (running as anonymous platform) clocked about 450 Mfips. Another thing I came across in the fftw docs is that for x86 cpu's, fftw runs faster if it is statically linked. That took a bit of tweakage in the guts of boinc-app-seti's autotools build system, but I managed to get it right. With that, and building all three packages with -march=k6-2, -ffast-math, and -3dnow, I'm clocking about 515 Mfips and the turnaround times are about 2.5 days. Also, since I worked from Debian pkg sources, everything is built into .deb packages that I can install and remove like any other pkg. Oh, and my kernel is a rebuilt 2.6.18 with -march=k6-2 and 3dnow activated as well. |
