Look at this WU: http://setiweb.ssl.berkeley.edu/workunit.php?wuid=5068229 Some workunits have a huge amount of noise, and the WU cannot be processed. If this is the case, then the application will usually throw away the WU. In BOINC it seems like you get a very small amount of credit if this happens. In classic SETI, SETI Spy would often report 100 spikes or more for such a WU within a few minutes of processing. <p> <img src="http://www.infinisoft.34sp.com/boinc/signature.php?project=sah&id=7813418" border="0" /> </p> |

So who's got the smallest credit then? |

> So who's got the smallest credit then? Right now, 0.16 but I have previously seen 0.00 (valid) if the time taken is only a few seconds. There will be others with 0.00 I'm sure, but I've none in my results list atm. :) |

If this can be count as a crunched one I don't know, but it has been detected as SETI@Home Informational message -9 result_overflow NOTE: The number of results detected exceeds the storage space allocated. Crunched in 00:00 seconds by my P4 2.4@2.88GHz. |

i thought something was wrong with my computer...but i see mine is not an isolated case...i have several WU's with fractional credit (less than one)...all completed in about 3 minutes...the smallest credit i've recieved is .17 i've had two that size. PROUD TO BE TFFE! |

Here's a low one! My machine asked for .07 but got less. ;) http://setiweb.ssl.berkeley.edu/workunit.php?wuid=4828860 Click the Sig! BOINC Wiki |

Here's another one I got that oddly enough was processed near the same time as the one in my previous post. My computer spent 0 seconds on it and requested 0 credits. The other crunchers seemed to have claimed some credit on it so I got some anyway. Workunit 5068227 Looked in stderr.txt and they say also: The number of results detected exceeds the storage space allocated. Processing these WUs at least gets the "bad" ones out of the available workunit queue. <p> <img src="http://www.infinisoft.34sp.com/boinc/signature.php?project=sah&id=7813418" border="0" /> </p> |

I know many WUs get mutilated by certain PCs, but look at this one, this one of mine ;) http://setiweb.ssl.berkeley.edu/workunit.php?wuid=1270022 I and somebody else returned normal results and normally claimed credits. The other guy got no credit at all. I'm still pending... The workunit stats 'error: Too many total results'. One resultID, with NO host stated 'outcome: Didn't need'. Two validation errors, and one client is downloading this workunit of a week now?!? And of course someone was able to crunch it in a little more then 600 seconds, while all the others had to spend at least 10000 seconds on it. Just a question, is this normal to happen? I'm not complaining about it, but my PC spend some time on it and I hate to see it go to waste. PS I know, i know, should have started a new thread... |

Currently my smallest credit is 0.30 for 160.67 sec. to finish a unit. Fot the "too many results" error I just started a new thread http://setiweb.ssl.berkeley.edu/forum_thread.php?id=7486 WinXP Home, P4 3.2GHz HT, 512Mb RAM. Running SETI, Predictor, Prime Grid, SIMAP, Folding |
