now that projects are over a 10 hour run time if you let your computer run only milkyway fine buy I run 5 projects plus other stuff it now takes a better part of the day to run a milkyway project at 65%of output on one processer ....we need more tie like a week for decent turn around i have had to abort projects because they were going to be late...mt pc is running boinc 92% of the time for your work lighten up and give us little guys a chance...we all can't spend 1000's for ultra high end computers....I have stuck with u thru the point fiasco...the week long shutdown so please give us a few extra days to complete your work...face it without us your project would be dead in the water......be blessed and merry Christmas and and a great new year,,,,, |

dreamweaver, I have spent thousands on ultra high end stuff this month, and I only run five projects! You need to ditch two or three projects, so things come back into balance for you. The astronomers are highly unlikely to allow Travis to extend the 3 day deadline. |

I've been aborting every project for weeks and suspending Milky Way. This is going to keep happening until the deadlines given are realistic. There is simply no way to get such huge workloads done in 3 days - unless maybe you let your computer on 24 hours a day and don't actually use it. It's gotten to be worse than cosmology@home. If they need something that big done that quick, put it on a supercomputer not boinc. |

Matt, I run a stock i7, NOT overclocked, the CPU is set for CPDN and Cosmology, the GPU is set for Milkyway and spits out a WU every ~ 25 - 26 seconds (2 x5970's). It is clearly a case of using the right tool for the right job. And, yes, I do run the box 24/7, its only job is to run BOINC. In the academic world, there is a saying 'Publish, or perish'. In the computing world its 'Upgrade, or perish'. When I first joined BOINC, CPDN in particular, for one of their projects, in big red letters, it said to me, you need 1.5 GB to play here! Ouch! I replaced my machine with a 8GB model, and then I discovered that on 8 cores 8 GB was still not enough to run Cosmology! So now on the Cosmo boxes I run 10GB. Not the cheapest of hobbies I admit, but there it is. BOINC is very equal opportunity, if your rig is up to it, you get to play.

In the academic world, there is a saying 'Publish, or perish'. In the computing world its 'Upgrade, or perish'. I expect that's true in some cases. When I started out in BOINC it was with BBC Climate, and that's all there was because a WU took 6 to 12 months to complete, or never if you tried to run another project. You guys just don't know how easy you have it. A WU crashing after 4 months was devasting. We got the credit for the partly completed WU, but we wanted to finish them. After months of crunching on one WU all we wanted to do was to complete it. So we took much longer to finish it, because every day we would stop BOINC and back the whole thing up, and restart. When the WU crashed, as they did from time to time when you ran another program on your PC, or played a game or something which crashed the thing. So we had to do a restore, and re-crunch up to a day, again, each time it crashed. So give Matt a break, stop basking in technology and let everyone take part. Not just those who make a habit of spending a fortune on the lastest IT and suggest that BOINC is built only for those with IT rich PCS and GPU accessories. |

I've also been informed my Pentium 4, 3.4GHz processor is plenty for this project. |

In the academic world, there is a saying 'Publish, or perish'. In the computing world its 'Upgrade, or perish'. Yip, I hate it when a model crashes after hundreds and hundreds of hours of work and power consumption. So we took much longer to finish it, because every day we would stop BOINC and back the whole thing up, and restart. When the WU crashed, as they did from time to time when you ran another program on your PC, or played a game or something which crashed the thing. So we had to do a restore, and re-crunch up to a day, again, each time it crashed. I am NOT saying he can't take part, but like you in the old days, he needs to choose projects suitable for his resources, as you do, and I do. Using my old computer, CPU only, I ONLY run one project at a time, cause that's all it will do. 24/7 I run Milkyway, switching it off for periods I run the shorter CPDN models cause I can finish them in a couple of months, well ahead of the deadline. |

Ugh, the crashing. Climate Prediction gives HUGE WU's but gives more than a year to complete. Unfortunately, it ends up "computation error" more often than not. |

You still get credit if WUs don't complete, by crashing or being forgetten about in bottom drawers with the moth balls. But they have one huge advatage in that if you have a PC without internet connection you can leave it crunching away for months on end without any food, air, sunlight or companionship. Hopefully when you peek in on them after a while they haven't died and left you without a will... |
