Announced just under a week ago: http://www.breakthroughinitiatives.org/News/6 We may get FAST telescope data from the Chinese. Also Parkes Observatory should have also begun observing as well. So prepare for more Breakthrough Listen data. |

This will take some time. We need another application to process the data. This will take some weeks (month) of testing at beta after berkely got the first tapes. With each crime and every kindness we birth our future. |

Oh definitely it'll go through beta, but I believe that the v8 app is heterogeneous, and should mean that the app has already been developed, just needs optimisations |

IIRC Fast uses other recorders so the files have a different format. So we probably need other apps. Thats what Eric told me. With each crime and every kindness we birth our future. |

Some application builds have parameters hardwired, instead of read from the tasks as they are meant to be. I try to avoid that kindof fake optimisation, but some can slip through anyway. Never know what could be buried in some of the code that hasn;t been looked at for a while :D (any app branch) "Living by the wisdom of computer science doesn't sound so bad after all.

This will take some time. Although the FAST telescope is now complete, it was reported that it would take up to three years for final commissioning and calibration. It will also take time for Breakthrough Listen to design, build, and deploy the head-end preprocessing and recording hardware. I read somewhere (but can't immediately re-find) a note that even the Green Bank telescope currently only has - I think it was - one-eighth of the planned processing and recording hardware capacity. Also, it isn't explicit from the BL press-release that FAST will be used for the primary capture of raw data: it's spoken of more in terms of re-observing candidate sources detected by other means. |

The link your looking for: https://github.com/UCBerkeleySETI/breakthrough/blob/master/GBT/waterfall.md The VEGAS instrument at GBT is a big digitizer. It samples at 20 gigasamples / s which gives 10 GHz usable bandwidth. Right now we only run one of VEGAS’s eight ROACH boards, so we get 1/8 of the total bandwidth (about 1.25 GHz). EDIT: I interpreted this: https://setiathome.berkeley.edu/forum_thread.php?id=78710&postid=1752922 SETI@home version 8 has been released. This version finally gives us the ability to process data from multiple sources, including the Green Bank Telescope. As heterogeneous, that is why I said that a new app shouldn't have to developed, since v8 will be able to process multiple sources. |

https://github.com/UCBerkeleySETI/breakthrough/blob/master/GBT/waterfall.md That's the one - thanks. |

The devil in details. We already passed that many rounds before: C++ totally portable, OpenCL can work with any vendor's GPU w/o changes... SETI apps news We're not gonna fight them. We're gonna transcend them. |

I will most probably remind you in a couple of month. Also i wouldn`t be surprised if we see first data examples until christmas 2017. What i do know is that chinese have almost endless man power. It just depends how important it is to them. With each crime and every kindness we birth our future. |

Also Parkes Observatory should have also begun observing as well. So prepare for more Breakthrough Listen data. Parkes is no longer providing EINSTEIN pulsar search data (last files, minus the ususal laggards) were crunched last month. Lots of cruchers will miss the 4400 credit Parkes files, but the cruching capacity will find a new home, like BL. |

Parkes wasn't actually 'providing' data to Einstein: Einstein was re-analysing recordings made during the Parkes multi-beam pulsar survey, which started in 1997. Several research teams had already searched this (public) dataset, but Einstein, using the most sensitive techniques to date, was able to find several more pulsars that had been missed by everybody else. But they've finished looking now. |
