I'm having more and more wu that end-up with a computation error status. I've had 15 hours worth in the last 24. I'm not sure what this means. My computer can't add, subtract, and divide, or it's not following program instructions? Do I have a rogue CPU? Could someone enlighten me - I can't find mention of it on the message boards. Thanks. |

The status specifically says "computation error". I can't find this in the FAQ. So what's happened when I get this message? |

I have several machines with 256MB running Rosetta without any problems..... Teddies.... |

I have several machines with 256MB running Rosetta without any problems..... 256MB is fine for a dedicated cruncher. The 512MB recomendation is for the typical type of computer running rosetta, meaning one with some other purpose and where rosetta is supposed to quietly eat spare cycles without affecting performance. If the system has 512MB+ memory installed then the amount rosetta uses will be too small a fraction of that to have a significant impact on the system's responsiveness. |

I have several machines with 256MB running Rosetta without any problems..... Really should go with 512 Meg or more for Rosetta. My HD started running hotter part the time Rosetta was running at first, increased ram from 512 to 1024 Megs and it colled off again. Run times also dropped by about 10%. 256 Megs will work but hit the swapp file to often and will burn out the HD. Pizza@Home Rays Place Rays place Forums |

Thanks for the reply and the time you took to look-up my stats. It's nice to know that it's probably not my machine, but it is discouraging to see the computer time go down the drain. I'm also not sure what you mean by increasing the swap time. If you find time in your busy schedule, maybe you can fill me in. Thanks, Tom. |

Putting the swap file on a second physical drive helps a bit also. |

I'm not sure what he means but he may mean the "write to disk at most" setting. Below are the two possibly relevant setting in your "general preferences". (These are from my preference) Processor usage Switch between applications every (recommended: 60 minutes) 180 minutes Disk and memory usage Write to disk at most every 600 seconds |

I think he means the time between application swaps. There is a setting for that in the prefs. I think the deafult is every 60 min, but you can set it to other amounts of time.

This will increase memory usage and make the program need more swap space which will mean slower wu times as writing to disk is vastly slower than RAM. The best solution for faster wu times is more memory, how much is up to you but 512 is the least I would use. If you still want more swap space go: start, settings, control panel, system, advanced, performance, advanced, virtual memory and adjust accordingly. Keep in mind any increase in hard disk activity decreases lifetime so the more RAM you have the better. e6600 quad @ 2.5ghz 2418 floating point 5227 integer e6750 dual @ 3.71ghz 3598 floating point 7918 integer |

excuse me for my english not very good (I'm Italian)... the last WU's that I download (HBLR_1.0_... series) give me all a computation error : |rosetta@home|Unrecoverable error for result HBLR_1.0_1hz6_314_44_0 ( - exit code -164 (0xffffff5c)) |rosetta@home|Unrecoverable error for result HBLR_1.0_1hz6_314_40_0 ( - exit code -164 (0xffffff5c)) |rosetta@home|Unrecoverable error for result HBLR_1.0_1b72_314_76_0 ( - exit code -164 (0xffffff5c)) and that after 6:27, 1:45 and 0:50 hours ... why? it's the first time that it happen thank you for the answer (please answer simply) p.s.: the client is 4.82 |
