Is anybody else getting more guppi work units than Arecibo ones? For me, this started happening about three days ago. Currently I have: 12 Arecibo units 59 Green Bank units I used to get about a 50 / 50 split. Cheers Mark |

Yes, similar here. 37 out of 200 tasks are Arecibo but i dont care much about it. With each crime and every kindness we birth our future. |

There's currently only one EDIT: Corrected "gbt" to "pfb". It's Arecibo splitters that are stuck. |

Ok, thanks, that would explain it. At least I'm not alone. On a side note... The guppies I'm getting are now taking about 13 minutes instead of my "normal" 22 minutes. I'm using the same application: MB8_win_x86_SSE3_OpenCL_NV_SoG_r3500.exe The only difference I see is the Estimated Computation size is lower at around 34,000 GFLOPS. Cheers Mark |

BLC will have different numbers following them. I'm sure someone can tell use what they mean. You will find that there can be significant variations in time to complete depending on what BLC# is. |

There's currently only one Well, I'll be darned. Sometime in the last few hours, on a Sunday afternoon, somebody apparently cleared the jam. Four splitters are once again turning out Arecibo tasks. |

All GPU tasks on the Linux box with its HD 7770 using OpenCl 1.2 are guppies. I have downloaded GPU tasks on my Windows 10 PC with Geforce GTX 750 using Cuda 50 and they are Arecibo tasks. Tullio |

A lot of the tasks recorded on 15 Feb 16 - ab, ac, and ad - are VLAR, so not being distributed to NVidia GPUs. I wonder what they were looking at that day? Edit - looks like it was the moon: http://www.naic.edu/vscience/schedule/tpfiles/KesarajutagS3039tp.pdf. Be interesting if we find something intelligent up there, but it might be a good test of Astropulse. Anyone see anything interesting when they were processed for AP, or did they just pick up the moon's radar station? |

A lot of the tasks recorded on 15 Feb 16 - ab, ac, and ad - are VLAR, so not being distributed to NVidia GPUs. I wonder what they were looking at that day? And it seems that most of 15fe16ac/ad tasks (non-vlar) sent to GPU's are -9 result_overflow's... |

Looks to me like that was the batch that returned almost entirely: In ap_remove_radar.cpp: get_indices_to_randomize: num_ffts_forecast < 100. Blanking too much RFI? |

BLC will have different numbers following them. . . Thanks for that ... Now I only have two questions ... 1) What does the numerical digit after the BLC indicate? (I think most people have noticed that 5's takes a lot longer to crunch than most of the others and I have wondered why) 2) How do you tranlsate a modified Julian date into a real world date format? Stephen . |

There's currently only one . . I can't wait till some of them come my way :) Stephen . |

1) What does the numerical digit after the BLC indicate? That was my original question that got derailed by someone posting Eric's explanation of the complete name. I'm still waiting for someone to come up with that answer 2) How do you tranlsate a modified Julian date into a real world date format? Google, it's a wonderful thing... http://aa.usno.navy.mil/data/docs/JulianDate.php blc3_2bit_guppi_57451_19304_HIP62472_0003 57451_19304 ----> 57451.19304 JD 57451.193040 is |

. . OK, thanks for that, now I will take a Tylenol :(. . . The basic answer is "it takes too long to do the conversion so don't worry about it". :) Stephen . |

2) How do you tranlsate a modified Julian date into a real world date format? Richard posted this Modified Julian Day Converter a while back. I keep it bookmarked. |
