If "1" never shown what about app's device capabilities listing? Does it show sometime other GPU selected? Yes, sometimes it has used the device 0 and shown it correctly on both lines of stderr. Unfortunately I had to revert back to the cuda applications, too many driver and computer crashes while running SoG. I may try again after tuning becomes easier. Maybe these cards (GTX970 and GTX650 Ti) are too different to run SoG smoothly on a same computer. |

Thank you for the information. I'll keep it in mind for the next time. For now I don't have time to experiment more. |

. . Hi Raistmer, . . This is probably nothing, it is the only error so far in probably over 500 WU's but here it is. http://setiathome.berkeley.edu/result.php?resultid=4974924416 . . . Very little information in the output but I thought it might be better to add it to the database :) |

0xC0000018 Probably if not repeatable, then a genuine bitflip (e.g from cosmic rays or radioactive carbon in the processor/ram). Workstation grade components with ECC memory reduce the probability of that. We've been referring to that as ' "Eddys in the spacetime continuum", "Eddie Who's Eddie?", "No Not WHo's Eddie, What's Eddie?", "What? What's Eddie doing in the spacetime continuum ?"

Just got two bad work units with missing header information it looks like. Both wingmates completed successfully, which suggests that the raw datafile had headers intact. |

So does that mean that computer mangled the work units just when it grabbed them for processing? Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

So does that mean that computer mangled the work units just when it grabbed them for processing? Many possible layers between the server and client CPU, from download through reading from disk.

So does that mean that computer mangled the work units just when it grabbed them for processing? there's an MD5 check after DL isn't there? And/or a size check? A person who won't read has no advantage over one who can't read. (Mark Twain) |

So does that mean that computer mangled the work units just when it grabbed them for processing? And we have seen that error message before, in other applications including CUDA, with no conclusive evidence that the data file has suffered any corruption at all. It seemed (IIRC) to be more prevalent on task restarts than initial runs. I think that the code generating that error message dates from the original Berkeley CPU code: checking that for trigger points might give us a better handle on what's really happening under the hood. |

So does that mean that computer mangled the work units just when it grabbed them for processing? Any prevalence more common than about once every 3 months on a given host, would indicate either a configuration, system or indeed client or application issue. Less frequently than that on sub-workstation grade componentry indicates noise (radiation). "Living by the wisdom of computer science doesn't sound so bad after all.

I actually think it was the BOINC shutdown that froze on exit and then blue-screened the computer that did it. Strange thing is that I always wait till a quiescent period in BOINC activity before I initiate a shutdown. That means no work units are close to finishing, all recently completed work units have successfully uploaded and BOINC is not close to asking for network communication. Only when all those cases are met do I shutdown the Manager and close the client. I can only conclude that BOINC was reading those tasks when the computer blue-screened.

I'd class that as possibly reproducible [Rather than Eddy/Eddie]. Can you try that ? (could take substantial hammering :) ) "Living by the wisdom of computer science doesn't sound so bad after all.

At least the error message gives us a file name and line number: !swi.data_type || !found || !swi.nsamples File: ..\seti_header.cpp Line: 216 // Allow old style headers to be parsed correctly. // jeffc - need this? //swi.fft_len=2048; //swi.ifft_len=8; do { fgets(buf, 256, f); } while (!feof(f) && !xml_match_tag(buf,"<workunit_header")) ; Looks like we've dropped through to some legacy code - perhaps we should have branched to a more modern path higher up? |

Actually, the error message is on line 232 of the current file. Are we using an outdated version of seti_header.cpp? |

I believe that type of failure and exit status is the first I've experienced. I am running the latest beta BOINC Manager 7.6.29(x64) which I believe has had some code changed recently to fix Manager exits compared to the last stable release 7.6.22(x64). Richard probably could say just what the code jockeys played with in the latest beta. [Edit] Looks like my copy of the beta is not the latest now.
