Just so you don't feel bad about your one work unit being invalid, when my big system's cooling pump died, the cards overheated and made around six thousand of them before I shut it down. Of course it had to be in the wee hours when I was sleeping. :^)

It's what happens and it's why the quorum system is set up the way it is... most of us are using consumer-grade (ie not very precise or reliable) hardware and operating systems, and running other things on our computer that can interfere. So invalids are occasionally generated and the project has to be able to weed them out.

No worries... eBay (and Amazon) will cover if you bought fake merchandise. Make sure to initiate a return with "Doesn't seem genuine" and open a case with eBay if there are any issues. eBay and Amazon got as large as they are for a reason. :^) (OK, many reasons, but this is one of them!)

Interesting how Chinese manufacturing of US bound products are moving to Viet Nam, Mexico and Guatemala......to avoid Tariffs.


One of the countries picking up much of the ex-Chinese manufacturing and ramping up their own economy and standard of living is India. I think this is a good thing, as politically moderate, democratic republic India is an excellent foil to the argument that a nation as populous as China needs to be a tyrannical authoritarian oligarchy in order to function.

(Moved from another thread.)
Please read over the first post; this is due to your device using Android 9. As noted some work units may complete properly and then the device may start using that platform that worked all the time.

I also bothered him directly as well... I can be quite a pest when required. :^)

Edit: Also for those wondering why automatic ghost recovery was turned off, you can thank computers like this one with currently 17,845 tasks "in progress" yet not a single valid one returned. Automatically re-sending ghosts would require the scheduler to check its task allotment list of 17,845 against the list actually present on the host whenever it requested work, ie every five minutes.

So, if it were automatic, three hundred machines as bad as this asking for work would be on average one per second. The scheduler would have time and bandwidth for little else.

The title of the thread seems a little misleading. It’s more referring to GPU-based cryptocurrency mining rigs, not specifically Bitcoin ASICS, which is what you have.


Good point, so I added "GPU-based" to the title.

SETTINGS: POWER & SLEEP. Turn off screen after 15 minutes of inactivity.


If you can't find it otherwise, I would disable this setting. There have been issues where certain video drivers disable the GPU when the screen power saver is active. You'll have to just manually power off the screen.

The BOINC client will take care of the error reporting on its own. To re-send any missing "ghost" tasks you can follow the process I linked below.

That may be as I note that the recommended cc_config <max_tasks_reported> value is 512, but there's no time limit it seems.

The maximum return rate is 255 tasks every 5 mins.

Nothing you do will change this. Even if it says “reporting 5368 tasks”, only 255 will make it through.


I've reported a queue of several thousand uploads in less than five minutes, 512 at a time manually hitting the Update button right after each prev. scheduler request was completed, watching them disappear from the BOINC tasks display until there were none to report. I've also done this several times (as part of recovering my lost tasks... have to clear out any to upload and report first.) If the above is true, where did they go? And why did it seem to be working?

It seems to be having a "bad hair day" even into the evening (1736EDT here.) Using precisely the same timing I've used until now, it's consistently refusing to do anything but send loads of new work... 170+ at a time so it's not a case of a too-full cache. I'm using NNT, disabling network within half second of the sched. request, quitting within half a second of the disabled notification, waiting until boinc and boincmgr are gone as always. I'll just forget it until tomorrow.

Edit: And now when I try it the next morning with the same timings, it's working properly. ¯\_(ツ)_/¯ is all I have.

Edit2: All done... 6,523 lost work units recovered in total. Thank you again Keith for writing this up and consistently updating it. :^)

I hope that this doesn't force a rewrite again (sorry, Keith) but after many times retrying I have concluded that it is impossible for me to force resends in the mornings here (Eastern timezone); instead I always get new work. I didn't notice that the time of day was the issue until now as I'm confident enough with causing it otherwise that I'm not the issue. It could be that the scheduler is very fast with a low load, or that there is some restriction, but I am following the same process with the same timings that has worked a hundred or more times in the evenings, and I can't get it to resend once. ¯\_(ツ)_/¯

May be something to keep in mind if anyone else has issues.

Edit: I did also make sure to run the cache down to >80 WU lower than full.

AP work units require OpenCL... try installing it via:

sudo apt-get install ocl-icd-libopencl1 


or just find "ocl-icd-libopencl1" in the package manager ie "Software" or "Synaptic Package Manager".

Thanks, Keith. :^) And change resend limit too.... since everything was stable at 40, it's been doubled again to 80 tasks per resend request!
So, even the largest, spoofiest queues should be recoverable with a reasonable effort.

Unfortunately not as far as anyone knows. Because these miners are ASIC, they are using custom chips designed only for mining so can't perform easily as general-purpose computers. For example, mining hashing (as far as I am familiar with) is completely integer bitwise based, whereas SETI@Home requires at least single-precision floating point and other projects ie MilkyWay require double-precision.

They would at minimum require a custom-written client to take advantage of their unique architecture, if this were even possible.

Breakthrough Listen is producing so much data that we're only able to process about one percent of it, so the more participants and computers we can get contributing the better!
(The other 99% is analyzed onsite, but ours is about ten times more sensitive.)
