CUDA for MacOS

[Miner29974]

Hi

do it exist a plug-in for macOS? If not is there a développer who can try do do it?

thank you

Nvidia dropped MacOS support after CUDA Toolkit 10.2. (11.x has no MacOS support)

CUDA Toolkit 10.2 allegedly works on 10.13 High Sierra. Unknown if it works on anything newer. Unknown how to use it in a build if it's any different than Linux.

None of the devs here have Apple anything therefore the lack of much support other than guesses. But usually Apple does something that breaks things anyway, like deprecating OpenCL and not really wanting CUDA to work either (both in preference of everyone switching to Metal, which nobody has so far).

Thank you.

I understand it is impossible to use my old macbook nvidia GeForce 320M to help my CPU to mine monero.

I am buying à computer to try it better ans with also a gPU for etherum. Is there on github a specific mining OS?

Best regards.

I have successfully compiled for MacOS High Sierra 10.13 with CUDA Toolkit 10.2 (the last version of OSX, and the last version of CUDA to support any MacOS). It did not work out-of-the-box and took some changes, I will clean these up and submit as PR, even though it doesn't matter anymore, but in case someone wants to run old software to make it work. Perhaps the CUDA Toolkit 10.2 can be installed on newer OS but nVidia claims 10.13 is the only supported one. Probably the driver is broken in newer versions so having a plugin that can't talk to a GPU anyway would be a pointless success.

Hello

Your job is great ! Do you think it will work with OS X Sierra and Cuda 6.xxx?

Thank you.

Minimum supported CUDA is 8.0 for any platform, and minimum GPU "capability level" (arch) of 2.0 (Fermi)

It should work with Sierra (10.12) with CUDA Toolkit 9.0 for sure since it says it supports 10.12 directly. Perhaps newer Toolkits still work but they all say 10.13.

Unless you mean arch 6.x such as Pascal based 60 or 61 (GTX1060 or such) then yes, CUDA 9.0 supports those.

Working build fixes in #104

If you could test a build and then a run. You may have to set the cuda->loader path in config.json to where the libxmrig-cuda.dylib is located. null was trying to load OpenCL for some reason in my limited testing (with no GPU).

It should at least locate the GPU and possibly will even work.

EDIT: has been merged into dev branch

[Spudz76]

Repaired the loader: null problem in main xmrig, pending PR. Then copying the libxmrig-cuda.dylib along side xmrig executable and null setting as default will work, same as other platforms.

EDIT: has been merged into main xmrig dev branch

I see you are actually meaning to use 320M which is too old for mining. :(

[Miner29974]

Yes, it is for play with xmrig and m’y old MacBook and try to learn about mining.

I dont understrand where to found in github the file to put next xmrig.

Thank you Regards.
