Host : http://setiathome.berkeley.edu/results.php?hostid=5940343 GPU/s : NVIDIA GeForce GTX 570 (1279MB) State : All (1567) · In progress (112) · Validation pending (506) · Validation inconclusive (136) · Valid (113) · Invalid (699) · Error (1) pm : Impossible. Unclear why Invalid. task 3053496078 wu 1270505166 Idly I was wondering why a wingman with Inconclusive was getting mostly Invalid, and looking at this wu and task left me puzzled. I am not involved in this wu, it was just one I happened to look at from the host Invalid list and ... no obvious error. But marked Invalid. Idle curiosity. |

A validate error could be the cause. As I understand it, that's a result outside of the valid range, such as a 0 when the field requires a 1 or 2. |

Sten, good spot, and the best part is he is shooting himself in the foot. |

Edit 2: Looking closer to his results, it seems that he manages to sneak some of them into the science database too, despite that Eric did something to stop that from happening. He even manages to get some as canonical results. Example: http://setiathome.berkeley.edu/workunit.php?wuid=1270273091 Maybe this happens only when Autocorr count: 0 Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |

For a result_overflow task with no reportable Autocorr signals, there's no easy way for the Validator to detect the work was by a v6 app. Also, there's no need to protect the science since v6 and v7 apps will report the same signals (assuming the apps work as designed). In addition, of the 33 "Completed and validated" v7 tasks for the host 22 were reported June 18 and earlier and have gotten that status by a credit granting script. Most of those do not yet have a canonical result chosen, a sure sign of action outside normal BOINC processing. For those which do have a canonical result because a third task has been completed, the result from 5940343 was not chosen. As there is no Linux CUDA SETI@home v7 application in release status yet, it's not surprising the anonymous owner tried to make the old version do the work. At least the small percentage of tasks which overflow without Autocorrs can be assimilated, that's some useful work. Joe |

... ban the IP-address he connects from also. I don't think I have to explain to you why this is bad or useless ;) (because I remember your responses here (so you have to know ways around IP): http://setiathome.berkeley.edu/forum_thread.php?id=64691&postid=1123474#1123474 ) You know that behind one IP can be many people (family/building/school/...) even millions in cases like this: http://www.securitykiss.com/ http://www.hotspotshield.com/ bad: you'll block all these people useless: anyone can get other/new IP this way  - ALF - "Find out what you don't do well ..... then don't do it!" :)  |

When it detects a v7 workload it enables autocorr and the processing of v7 packets takes much longer compared to the v6.

Thanks for the app_info.xml, John. Looks like it should work for me assuming my 1GB 560 TI can do just 2 instances on V7. Was doing 3 instances <count>0.33</count> successfully on V6. I too have x41g installed on Linux 64bit from when we were on V6, but was a bit unclear if it was ok to use, so was not using it. Extremely busy the next 2 weeks, so x41g will have to wait. Never imagined this thread would result in app_info.xml help :-) |
