Hi folks, I am trying to get my MBP to crunch GPU tasks. Boinc Event Viewer sees the GPU but no tasks are run:

Sun Jun 24 22:09:55 2018 | | OpenCL: NVIDIA GPU 0: GeForce GT 650M (driver version 10.30.33 355.11.10.10.35.101, device version OpenCL 1.2, 1024MB, 1024MB available, 156 GFLOPS peak)

However it also sees the built in Intel GPU and lists them both as "GPU 0" so maybe this is the problem?

Sun Jun 24 22:09:55 2018 | | OpenCL: Intel GPU 0: HD Graphics 4000 (driver version 1.2(May 8 2018 16:00:00), device version OpenCL 1.2, 1536MB, 1536MB available, 154 GFLOPS peak)

I suspect I'll need to set something in app_config.xml ??

Thanks!

Other notes, I am running latest OS update "High Sierra 10.13.5" and have toggled "Automatic Graphics Switching" both on and off to force it to use the dedicated GPU, with no change in BOINC (no GPU task is downloaded/ran).

I suspect it will need to be done with the app_config.xml I just do not know the proper syntax

Any suggestions on how to utilize the Nvidia GPU?

Thanks

I have added this and relaunched the client, it still will not download Nvidia WU.

/Library/Application Support/BOINC Data/cc_config.xml

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

Hi, sorry, there is no GPU app for MacOS at present. There is only CUDA app for linux and Windows now.

Ahh I see. Well that explains it! Thanks Kyong.
