HOW can the following be doing wus so quickly..And how the hell do you get those figures using 1gig of ram?. CPU type GenuineIntel Intel(R) Pentium(R) 4 CPU 2.80GHz Number of CPUs 1 Operating System Microsoft Windows XP Professional Edition, Service Pack 2, (05.01.2600.00) Memory 1014.07 MB Cache 976.56 KB Measured floating point speed 15354.81 million ops/sec Measured integer speed 5270.92 million ops/sec Does wu's in 2000s, thats just over a half hour to you and me..not just 1 or 2 wus, all. I dont understand. |

I've seen a few setups like that with the extreme FPU numbers. Obviously they are using an optimized client, which one. your guess is as good as mine. |

HOW can the following be doing wus so quickly..And how the hell do you get those figures using 1gig of ram?. my guess: he is running the Crunch3r optimized aplication(SSE-2), non-hyper-threaded, slightly over clocked, with an extreme ventilation (possibly water cooled) set-up. If I wasn't running HT, many of my machines would be turning WU as fast, or at least close to his times. Sparky [edited for spelling errors] |

I've got a simple laptop with a 1.4 GHz Intel(R) Celeron(R) M processor that is cranking them out in 8000-10000 seconds. With twice the speed, and the other advantages of a Pentium 4 processor I'm not surprised to see it 4 to 5 times as fast as my laptop. And I've only got 512 MBytes of RAM. Keep on crunching. |

with an optimiced client and overclocking ist it possible my pentium-d 820 crunch 2 wu´s under 1800sec greetings ralf Boinc runs here on: Intel i7-3770K + IntelHD4000 Android-Stick-ARM-Cotex-A17 Sony-Z5C-ARM-Cortex-A53/A57 Nvidia GT-630 / Nvidia GTX-750Ti |

THats some serious tweaking then.. Maybe i need to have a fiddle too. |

That is not as bad as this Pentium D 2.4 that I came accrost. And he is doing 2 at a time. I thought the slowest Pentium D made was the 2.66?? This has to be faster than a 2.4, BOINC reading the CPU wrong or something. Many units turned in at ~850 seconds. But he (or she) is using the standard BOINC with the optomized SETI so claiming real low on the credit. |

I go to "Top Computers" at the right of the main page. With Pentium Ds I see that the great majority use Windows XpPro, but I see a few Win Servers and Linuxes. The three I checked with XpHome don't seem to have worse times, although the one that has four processes (must be a D955 Extreme hyperthreadable dual-core) turns out crummy throughput inferior to that of the other two-threaded setups. Maybe XpHome is sufficient for Pentium Ds and won't hurt throughput. But it looks like the 955 stinks. Multipliers (true time over tabular time) was about 0.556, 0.664 (and 0.795 for the 4-process 955(?)). This sample (three total) is very small, though. |

This has to be faster than a 2.4, BOINC reading the CPU wrong or something. The 2.66 is the slowest Pentium D that I have seen, but a celeron would not do those times eather. The computer ID page for that one says: GenuineIntel Intel(R) Pentium(R) D CPU 000 @ 2.40GHz Why the CPU 000, I have no idea. |

Why even bother to compare the Celeron D's in the first place...their L2 cache is only 250Kb x 2 compared to 1Mb x 2 for the Pentium D. Account frozen... |

@dogbytes only for info there is no celeron-d dual core they are all single cores Boinc runs here on: Intel i7-3770K + IntelHD4000 Android-Stick-ARM-Cotex-A17 Sony-Z5C-ARM-Cortex-A53/A57 Nvidia GT-630 / Nvidia GTX-750Ti |

Hi Crunch3r, that would be an ES part, right? Do you have any details on this system? Regards Hans |
