Version for MacOS with Apple M1 processor?

[Sara4711]

Hi I have been using Folding at Home for some time but now that I purchased a new MacBook Air with the new Apple M1 processor it does not seem to work. Is this something that can be fixed easily or do I have to wait for a new version of Folding at Home?

[Joe_H]

Welcome to the folding support forum.

There has been some discussion about this in another topic - viewtopic.php?f=16&t=36425. It then veers into discussion about the GPU provided as part of the M1.

My guess is if the emulation available through the Rosetta 2 translator is not able to handle the F@h client, then a new version will be needed. No idea when that might happen.

Can you provide any details on how the client fails to work?

[Sara4711]

Thans,

I will check that thread. I got my new MacBook Air with the M1 chip yesterday.

The client starts up but says

"Client: local Connecting Inactive"

It stays like that indefinately. Is there any logfile I can look in?

[Sara4711]

I tried de deinstall and then install again and now I can´t start up the FAHControl at all. The web interface indicate says that I am using CPU 7 and it is ready but it does not seem like anythong is actually processed.

There is however a FAHClient process running in the computer that is consuming a small amount if CPU time.

[Joe_H]

Log files along with other files related to running the F@h client are located in /Library/Application Support/FAHClient. The client apps are installed into a folder under Applications called Folding@home.

FAHControl and the Web Control connect with the background FAHClient process using port 36330 on the local network IP 127.0.0.1. Personally I am nowhere near running the most recent OS, Big Sur, so am not familiar with any issues that may come from changes in default security settings for the OS or Safari using Web Control.

This is what can be found in the log. It repeats

19:39:52:WU00:FS00:Starting

[Joe_H]

Okay, that looks like where the problem with actually processing a WU might be. The client and server appear to be detecting the M1 as supporting AVX instructions, but my cursory look at what the Rosetta 2 emulation supports is just up to SSE 4.2. So it appears the wrong folding core was downloaded and installed for use. I could be wrong here, it has been a while since I did much digging through developer documentation on the Apple site, so quite likely have missed something.

On another bit, could you post the first 100 or so lines of the log file. That would at least let us see how the client detects the hardware and software when it starts up. That may give some clues for future development.

And then it continues like that

Thanks for posting the log. From the CPU ID shown in the log, Intel Family 6 Model 44 Stepping 0, the Rosetta 2 emulation is of a family of Core i/Xeon processors from about 9-10 years ago. SSE 4.2 was the highest level of instruction support, AVX was added to the next generation of Intel chips.

Potentially the current client or server code could be updated so it properly detected the CPU and downloaded the non-AVX version of the core which should run. Or it might run into other issues. Not sure of the rest of the network communication issues between the client process and Web Control or FAHControl, not many reports yet on running the client on Intel Mac's running Big Sur.

So for now it looks like the Apple M1 will not be usable, it may take a while for it to be added to the supported hardware. Whether they will be coming out with a native version or just adapting the current client I don't have an idea on yet.

[calxalot]

Interesting that it almost runs as-is.
Does FAHViewer run?

[Sara4711]

Yes it runs but it can of course nor show any data being processed sine none is processed.

[Sara4711]

Found the following on the apple page

What Can't Be Translated?
Rosetta can translate most Intel-based apps, including apps that contain just-in-time (JIT) compilers. However, Rosetta doesn’t translate the following executables:

• Kernel extensions
• Virtual Machine apps that virtualize x86_64 computer platforms

Rosetta translates all x86_64 instructions, but it doesn’t support the execution of some newer instruction sets and processor features, such as AVX, AVX2, and AVX512 vector instructions. If you include these newer instructions in your code, execute them only after verifying that they are available. For example, to determine if AVX512 vector instructions are available, use the sysctlbyname function to check the hw.optional.avx512f attribute.

Before I was running the M1 MacBook I was running on a Intel based MacBook that was also running Big Sur and that worked so I think the issues is only related to the fact that the M1 CPU has to run Rosetta 2. So with a none-AVX version of the code it might run correctly.

[JimboPalmer]

So with a non-AVX version of the code it might run correctly.

The M1 version of ARM does not necessarily emulate SSE2 fast enough to complete WUs.

Ideally, some one with deep pockets and intimate knowledge of the M1 would aid development.
