Been goin for couple days now and all i get are these tiny wu's that finish in 5 mins or less. Just checked and my work buffer was only set to .25 days. Could that be why im not getting larger WU's? If thats the case whats the smallest buffer i could use and still get all sizes of wu's. I upped it to 3 days buffer now and it has 10 gigs max. Would rather have it under a day if it doesnt matter Edit: Also what is considered normal RAC? Seems i can get 5000 credits per day no problem but i see some peeps with 14k RAC's. Is that just multiple comps running same ID? |

Size of received SETI@Home workunits is nearly equal, ~375Kbytes (differs text part with tags) for traditional S@H and ~8Mbytes for Astropulse. Processing time differs due to data recorded from telescope and algorithm used for calculations. |

Ok got an 8 meg AP now. But i wasnt getting them with the lower buffer. if i lower from 3 to will will i still get them or is that something differnt for everyone and i just have to tinker? and whats considered normal RAC, damn good RAC, and Crazy RAC? |

The high RACs you're seeing are on what we call farms. Many computers running under one ID.They are usually at least quads and they crunch huge amounts of WUs fast. Your RAC will depend on what kind of computer(s) you put to the task. You've got a really good machine there so expect to see your RAC climb pretty fast. You might also want to poke around on this site and read up on adding an optimizing app. It will help you go a lot faster. If you have any questions about this don't be afraid to ask. We have many people on here that are only too happy to help. PROUD MEMBER OF Team Starfire World BOINC |

Ok. Thanks both for the help. I have been readin a bit about the optimizin app. Do they work for 64bit vista? couple ive seen werent labled of r64 i think NM. Found one. gonna let my list clear before i mess with it i think |

Ok got an 8 meg AP now. But i wasnt getting them with the lower buffer. if i lower from 3 to will will i still get them or is that something differnt for everyone and i just have to tinker? Don't afraid to set harddisk buffer too much - BOINC will fill it with workunits not up to allocated size but up to processing time "Additional work buffer" in days. Even 10 gigs will not filled if additional buffer small. For example, stock application on my Core2Duo 2.4 is processing Astropulse workunit about 2 days, so if I will set that additional buffer for 2 days, I will receive 2 workunits for current processing with my 2 cores plus 2 workunits avaiting - so only 24 Megabytes will be filled... Recently Approved Credit (RAC) - is the mean quantity of recently completed workunits, calculation result from which was approved (is equal) by another cruncher (so-called wingman). So, RAC depends on computing power of your computer and on same thing from your wingman. If you was first in completing of workunit, you will wait for wingman. If wingmans as fast as you - your RAC will be stable. If they will compute slower - RAC will drop (bad RAC). r64 has no meaning with 64bit OS, rXXX - it's a release version. You can find optimized applications at specialized sites, but check possibilities of your CPU with program CPU-Z first - to choose correct application. |

Not too worried bout the HD space. I have a terabyte, its just i dont want to have to wait 10 days if i want to clear my list : P I guess once i have it all set up it wont matter. But in another thread someone recommended letting you list clear before optimizing incase you clear your cache or something. Im not sure but i know i have a couple "disconnected by client"s from when i was trying to make graphics work before i found out you couldnt have them on CUDA : ( |

I have a terabyte, its just i dont want to have to wait 10 days if i want to clear my list First of all, keep in mind that aborting tasks in BOINC Manager makes those workunits immediately available to processing by other crunchers. If you wish to crunch with optimized applications then you can wait slight less than 10 days ;) If BOINC was installed in no-service mode (called protected), then set project to "No New Tasks". Abort tasks which are not running. Wait until running tasks completes. Then exit manager (with closing scientific apps - they must not present in Windows Task Manager) and unpack optimized apps in desired directory. Start manager. |

That you got no AP WUs had nothing to do with your cache buffer setting, there simply weren't any available at the SETI site. If enough work is ready to send, you'll be perfectly happy with a buffer of 0.1 days. Gruß, Gundolf Computer sind nicht alles im Leben.
