It's been 3 days now since I have received my last Seti work unit. Is there no more work units to be done for Seti at home?

Plenty of work available, must be something at your end

Can you restart Boinc and post the first 30 or so lines from the log here, so someone can help.

Found at Tools-> Event log or Ctrl+Shift+E

Part of the issue might be you are trying to crunch gpu tasks on your iGPU. Very few people have much luck doing that. It usually slows the whole system down by 50% or so.

I 2nd the request for the first 30 lines of your Boinc log after you restart Boinc.

You are running multiple projects on what is an extremely low powered system. Your system is hidden on one project, but on another I can see you have 2 WUs in progress, and it takes 3 days just to process 1 WU (and they have very short deadlines- only 11 days). Depending on your resources share settings, and any work for the project your systems are hidden on, it could just be case of Seti honouring you Resource Share settings.
Once the work for the other projects has been done, it may very well get some more Seti work.

The more projects you do, the bigger the difference between project deadlines (11 days for one project, 2 months for another), the less powerful your hardware, and the larger your cache settings, the longer it will take for BOINC to honour your Resource Share settings.


As the others have mentioned, you would be better off not using your iGPU to process work, as it doesn't have much processing abilities itself and it's severely impacting on the CPUs already limited abilities.

I have been away from SETI@Home for a while. But now I am back.

Question: What is the maximum number of SETI@Home WUs that can be processed at the same time?

Hardware: The cpu in the desktop I am using is an Intel i7-8700K. According to the documentation I have read this cpu has 6 cores and with hyper threading = 12 threads = 12 work units processed at the same time. Currently only one WU is being processed.

Something is screwy here. Can someone help me out here?

As I mentioned in my earlier post, the number of projects you are attached to, your cache settings, your Resource share settings & system capabilities will all impact on how much Seti work you do at any given time, along with settings for when BOINC can actually process work. And since you have recently attached to Seti, it will take quite a few completed Work Units before the Estimated processing times become accurate- until then the BOINC manager won't know just how long it takes you to process work, so it doesn't know how much it can give without running in to deadline problems.

If you increase the size of your cache settings, it will increase the amount of Seti work you can get. However it will take longer for your project Resource share settings to be met. Or if you just wait for a week or so (it could be much less if your system is on 24/7 & BOINC can process for all of that time) the deadlines will match reality & then it should be possible to get more Seti work.
If after the deadlines have settled down you're still not getting much Seti work, try changing your project Resource share settings in Seti's favour- although at present you are processing plenty of GPU work, it is only the CPU work for Seti that is limited.


The BOINC manager doesn't discriminate between CPU or GPU work when it comes to Resource share settings- since the GPU can process 20 or more times work than the CPU, projects that use only the CPU will get most (or maybe even all of) the CPU processing your system can do, as projects (such as Seti) using just GPU will still meet your project Resource share settings.
