Why is this result NOT an --9 Error, or information overflow?

iirc the maximum is 30. So 30 get reported 31 don't. Carola ------- I'm multilingual - I can misunderstand people in several languages! |

I have seen -9 overflow with 30 pulses or spikes, should have saved them. I take it, you're right on this one, 31 is a true result overflow Anyway I'm ofc glad it's OK :) From time to time, I have to see some valid results ;^) . . .

iirc the maximum is 30. So 30 get reported 31 don't. But IIRC the app stops processing and errors out if it reaches 30. Could someone more knowledgeable comment, please? |

iirc the maximum is 30. So 30 get reported 31 don't. quoting Joe: result_overflow is triggered by the 31st found signal that knowledgable enough for you? Carola ------- I'm multilingual - I can misunderstand people in several languages! |

Added in the above mentioned post! How about this WU? Have never seen this before, I mean why has it normally ended?!? It's nice getting credits for this Result, but what is the result? WU true angle range is : 0.378217 Flopcounter: 47581855434324.695000 Spike count: 5 Pulse count: 2 Triplet count: 0 Gaussian count: 1 called boinc_finish </stderr_txt> |

I have seen -9 overflow with 30 pulses or spikes... Probably the 31st one doesn't get reported in the log, so 30 events reported without overflow => 30 found; 30 events reported with overflow => 31 found but only 30 shown. Gruß, Gundolf |

Ahmmm sorry to disagree. I had some units with 31 pulses reported. More than 1. With each crime and every kindness we birth our future. |

IIRC the overflow is hit if the 30 results are found before a certain amount of the WU is done. In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

Ahmmm sorry to disagree. That's right. The 31st signal does trigger overflow, but if it's a Pulse, Gaussian, or Triplet it also gets reported. If it's a Spike (or Autocorr for S@H v7) the quit logic is ahead of the report logic. Joe |

And to make sure this will be clear I've found a example of 31 signals are reported, as joe explained. ;-) v_BaseLineSmooth (no other) v_vGetPowerSpectrumUnrolled 0.00009 0.00000 sse3_ChirpData_ak 0.00969 0.00000 v_vTranspose4 0.00138 0.00000 AK SSE folding 0.00149 0.00000 SETI@Home Informational message -9 result_overflow NOTE: The number of results detected exceeds the storage space allocated.
