I don't receive wus with my 3 Windows 10 client So, i install a little linux virtual machine: no result! "Got 0 new task" |

I have plenty (i.e. 24) BHspin v2 in progress, the most recently downloaded an hour ago. http://universeathome.pl/universe/results.php?hostid=45027 This is on an Ubuntu 16.04 machine with BOINC 7.6.31 and the default buffer size. |

I'm speaking about reionization wus, not bhspin OK, I haven't gotten them either for a while. I got the impression from the first announcement that they would be releasing them in batches, and so the first batch may be finished. |

While I guess the server status might include a bad batch, not deleted properly, it's more likely that I'm just not getting tasks on any of my systems, possibly because they don't match other systems architectures (CPU Family), though I'm not sure of that having just looked at a Xeon validate against an AMD Athlon. Lots of server side changes make it difficult to follow what's going on. If we're not getting tasks because of CPU Family pairing (or mixed-pairing) then an appropriate message would be helpful. Presently BM only gets sent the generic "No tasks are available" message which is misleading/confusing/not helpful (which is the purpose of a message); hence all the posts here and no tasks being sent to many peoples systems. Noticed that I was getting tasks on one of my systems until 139 were tasks were "Cancelled by server" on the 4th Sept. 202 (0xca) EXIT_ABORTED_BY_PROJECT. Maybe there was a project change at that time? Before the server cancellations there were 522 consecutive successful tasks. Would having lots of errors against it prevent it getting new tasks? Others seem to be in the same situation but get tasks. The tasks had a minimum quorum of 2 and an initial replication of 3, but the server was set to automatically abort the 3rd task if the first two were reported and validated (might only be if the 3rd task doesn't start). My tasks were cancelled within 2h of being sent, which is too tight even for my 0.01 cache and average turnaround time of 0.10 days for those WU's. Seems odd that you would send out a task on 24th Aug, which got reported the same day, but not send out a second task until the 4th Sept and then send two tasks only to abort 1 after 1.5h. Guess you changed the parameters and they are produced in batches which initially had a 10day turn around. Anyway, I've only received 1 task from 5 systems since 5th Sept, so is there anything I can do at my end to get tasks? |

I am not getting any results at the moment on one of my hosts. Because cancelled results are marked as error, this host has lost its "trusted" status. And resends are not send to a host without a "trusted" status. I have therefor a Catch 22 problem. I get no work because my host is not "trusted" and I cannot earn the "trusted" status because I get no work. This is a deadlock situation in de server setup. |

So the server aborts are negating the systems credit rating and good systems are getting no work? My attempt to get work: As I only had QuarkStars & Ultraviolet reionization apps selected and wasn't getting tasks on any system I added BHspin v2 (hoping that the system ratings are not applied to that queue) and received 16 new BHspin tasks on one system. I was banking on them completing quickly and improving the systems status in the hope that I would then be able to switch back to the 2 apps and get work for Ultraviolet reionization. Unfortunately they downloaded with an estimated runtime of 10min which is now looking more like 4h (with the remaining time going up and down). Guess it'll be a day or two before I get any Ultraviolet reionization tasks, if they are still around then. I'm assuming the computer status is calculated (and not displayed) on a system/project basis rather than app basis... Tried the same on another system and initially got the "Tasks are committed to other platforms" message - so that has been implemented. When I manually asked again I got one task that will take 6h to run... I suspended other CPU tasks and waited in vain for BM to ask for work despite increasing my cache. It's a pain at this end too. |

If you look on your account page at "computers on this account" and then "details" and then "Application details" you will see that the valid task count is per application. So running one application to get "trusted" status overall will not work. |

Well, it was a guess and I can neither remember how the trusted/rating system works or think of anything else to try at this end. If I look at my Consecutive valid tasks (1465) for the Ultraviolet reionization app (on one system) it doesn't suggest that it would have a low trust status with the server:
Number of tasks completed 1466 Max tasks per day 2465 Number of tasks today 0 Consecutive valid tasks 1465 Average processing rate 0.14 GFLOPS Average turnaround time 0.10 days The app details don't actually give the systems trusted rating or elude to the parameters the server might be enforcing to select systems and there is no mention under the app of failures. For example, there could be a bandwidth restriction enforcement that requires you to have a low contention and fast upload/download transfer rates or a turn around or runtime of no more than x minutes. |

Yes, it is deadlock situation so I will not use any more reliable hosts option. Krzysztof 'krzyszp' Piszczek Member of Radioactive@Home team My Patreon profile Universe@Home on YT |

You could still use "reliable hosts" based on all the apps, rather than a specific one, as I think skgiven was implying above. Then, if one app had a lot of "errors" due to server aborts, or anything else, it would not necessarily destroy your status as a reliable host. And even if it did, you could quickly regain it. I seem to recall trying something that myself once, and it worked OK on another project. |

I have not received any new Ultraviolet reionization units for two days on either of my Raspberry Pi 2s. I am out of work now. When will I be able to get work again ? Thanks, Tom |

Yes, it is deadlock situation so I will not use any more reliable hosts option. Still no work. Is the disableing of this option in progress and should I just wait until your done or is there something else that is blocking work transmission. |

Just to give an update since my original post my laptops are not having no issues getting work units. The server that I had attached at the start of this post still is not receiving units and now my raspberry is not getting new units. I had to shut it down to move it, but I saw that it was sending back units after I turned it on. |
