1) Message boards : Problems and Help : Discrete GPU on MacBook Pro (Message 146639)
Posted 126 days ago by zombie67 [MM]Project donor
So this just happened:

I have a Mac mini with an Intel CPU which includes the integrated GPU. It is attached to an eGPU with an AMD RX 580. I use the eGPU to crunch PPS since it's not competitive on other projects.

Anyway, I had to reboot the machine for an update. Upon restart, BOINC started running the task on the Integrated GPU, instead of the eGPU. This is even with the line in the cc_config.xml that I posted earlier. This is not the first time this has happened. So I quit BOINC. I restarted BOINC. And now everything is back to normal. CPU tasks running on the CPU. GPU task running on the eGPU.

That didn't change anything.


I have found that sometimes, just requesting BOINC go re-read config files doesn't work when it comes to controlling the GPUs. So I will reboot the machine just to be sure. Perhaps try that if you haven't already.

Another thing to check: System preferences. There used to be a setting to tell the Mac to always use the discrete GPU (along with a warning that it will use more power/battery). I am not sure if that setting is still there, since I don't have one of those Macs any more. But if it exists, make sure that it is selected.

Add this to your cc_config.xml:

<ignore_intel_dev>0</ignore_intel_dev>


You may need to change the device number. Look at the event log at startup to see what number BOINC assigns it.

To be clear, I was not advocating that PG should do this. Only that it was technically possible using BOINC.


Are both gpu's the same in the machine?

In the one I sent the link to? Yes. Both 1660 Tis. But they don't have to be the same at Moo!

FWIW, here is the stderr output from a moo tasks running on two GPUs. Not sure how long it will stick around, so look quickly.

7) Message boards : Number crunching : Why are GPU-capable subprojects also run on CPUs? (Message 146281)
Posted 132 days ago by zombie67 [MM]Project donor
It seems that you are assuming that CPUs excluded from GPU sub-projects would naturally be used for CPU-sub-projects at PrimeGrid. Perhaps they would just move to other projects all-together. CPUs on GPU sub-projects at PrimeGrid is better than no CPUs at PrimeGrid at all.

Personally, I want to be able to *also* run CPUs on GPU sub-projects, in order to achieve hour-based goals on wuprop.

Moo! runs a single task across multiple GPUs. They do RC5-72 for distributed.net, in a BOINC wrapper.
Has this been specifically written to do so then? It seems Boinc doesn't have this ability built in. What do you see in Boinc Manager / Boinctasks when you do this?


Standard BOINC client. Not sure what was done inside the wrapper of the task. Here are a couple of screen shots, from both boincmgr and boinctasks.

10) Message boards : Proth Prime Search : pps_sr2sieve no longer recognised ? (Message 145722)

Cheers got this in place to do 3 sieves at a time on GPU otherwise not fully used (if can be done on that page I will ?)


Ah. Got it.

You could remove the parts of the app_config.xml that you aren't using (the ones causing error messages in your event log).
