Based on the relative performance comparison, if you got it folding it should meet all the deadlines and such, and I'd guess be worth 60-65K PPD. It's not much slower than the Vega 11 on my machine.

That being said, I don't mind letting this machine run 24/7 to fold. But if I had quick GPU's like you do, I think the energy would be better spend letting them fold more often. It should be even more power efficient in the long run, and why set up a slow rig to fold if it's not very efficient?
It could pave the way for ARM CPUs driving GPUs, basically the best of both worlds.
We're not there yet, but people like Jeff Beerling is slowly starting to get some GPUs work on the PCIE x1 slot on the Pi 4 (CM4).
It won't take long before all drivers will be updated, and a Pi 4 could run a lower end Nvidia GPU.
I don't think we'll see it drive RTX GPUs anytime soon (other than for bitcoin mining, or The Collatz Conjecture, that use very little CPU and PCIE bandwidth).

As promised I made a small spreadsheet and notes on what I came up with. Work and the holidays had me a bit distracted so it's a little late where I forgot to upload it. As it was stated you can only do a 1:1 ratio of GPU's to CPU threads. Unfortunately it does lock them out even though the real usage would accommodate for a higher GPU count if it did not. Since I had ordered the 6 cards before being aware (My fault for not researching it better) I went a head and tested it since some people seemed to allude to the more recent update changing this possibly. Overall as always I enjoyed the build none the less and when I build my NAS server I might even move them over to it. Next project is to see how well a Tesla M40 or K80 does. I don't expect great things from them but I'm going to use it to dink around with ML/AI so I figured I'd spin it up since it's going into my VM server anyhow. This may be helpful or maybe not, I'm also sure some of the notes are somewhat common sense for most people who have folded for awhile. It's habit and for anyone who may stumble across this down the line though.

Disclaimer: This is not a definitive guide, PPD will change depending on the WU, Cause Preference, Over/Under Clocking, and even room temperature if it doesn't cool your equipment properly. Heat is a natural enemy of electronics, keeping them cool increases efficiency and extends the life of your folding equipment.

        Note: After testing going beyond Core Clock offset of +125 no benefit noticed									
	Note: After testing going beyond Memory Clock of +200 no benefit was noticed									
	Note: 80% was the lowest Power Limit for these GPU's. Increasing it a long with Core or Memory Clock seemed to have no effect other than increased wattage and heat		
        Note: CPU Thread are a 1:1 ratio to GPU's, I tried 6, but the i3-7100 only has 4 threads therefore any more than 4 GPU's and the system overall took a hit and wasn't worth using so I pulled them and scaled it back to 4 total.

You should try to use the

The bulk of the engineering work that you suggest needs to be completed to run GPU folding on Jetson is already completed as of September. (There was F@H CUDA blog post, but I lack permission to include URLs.)

The OpenMM project (and by extension, the core22 folding core) builds and tests well on Jetson GPU via CUDA. There must be additional conditions imposed by FAHClient that restrict this folding core from running on Jetson GPU (e.g. GPUs.txt, perhaps?), as the fundamental core is functional on Jetson GPU. As far as I know, FAHClient remains closed-source, so this actual logic used to lock-out using core22/GPU/CUDA remains a mystery.

It would be nice for the Jetson users if whatever that final switch is could be enabled for Jetson GPU.

If OpenMM builds and tests well on Jetson GPU via CUDA, that's a good start. However, FahCore_22 does use a tweaked version so we would have to test that out. Moreover, the restriction of GPU comes from the Servers. We don't know what the PCIe Device ID is so we can't add it to the list. You can provide it here but it may not get added to the list just yet. Moreover, can you actually run FAHClient on it? That would be the first step.

Considering that it's a new hardware type, additional work would be involved to ensure that whatever data it processes, generates valid data. I don't think that the primary developer of FahCore_22 has access to Jetson.

Do note that there are plans to have a new version of FAHClient (and other components) that is open source which would allow the F@H Community to engage and contribute to it.

Thank you PantherX for the warm welcome. I appreciate the insight shared in your reply.

FAHClient does run on Jetson. The CPU side of things is aarch64, so the recent ARM support in FAHClient helped a ton there. I have successfully ran/submitted some work units that run on the ARM CPU. The PCIe Device ID is a curious topic. As an embedded platform, the GPU is not identified by a PCIe link/ no link exists (at least, not identifiable by lspci). There are other tell-tell signs that a platform is Jetson, eg. availability of CUDA and Device 'Compute Capability' = 7.2 for Volta-generation Jetson products, 6.2 for Pascal-gen, 5.3 for Maxwell-gen.

Jetson is supported by nvidia as a CUDA platform, so I would expect that it goes through similar scrutiny to specific GPU models that may be similarly inaccessible to developers. (Except for the no-PCIe Device ID issue/workaround, which would definitely be easier with hardware access.)

If FAHClient can start-up that's great! Would it be possible for you to share the log file which includes the first 100 lines for us to see what happens?

If FAHClient is unable to detect the GPU, which I suspect is the case, then it's not a trivial matter to modify the GPU detection.

It appears the GPU is detected as a CUDA device, but it does not get included as a "GPU".

Re: Need help selecting a Processor

Thanks for the log file. It seems that using the GPU would require FahCore_22 running on ARM platform. That's a massive undertaking and one that I am not sure would be feasible since there's other stuff in the pipeline for the future of FahCore_22. However, this could be revisited in future :)

Thank you for the discussion. I'm hopeful for the future, but definitely understand the reservation given the required investment.

I tried to do some searching, but now figure its easier to just ask: Is FahCore_22 open source? if not, is there potential/discussion for it (or the 'next' core) to become open similar to / with future FAHClient?

OpenMM on which Core_22 is based is open source, the core itself is not. There is discussion and work being done on making the client fully open source, some parts already are.

The code the CPU folding cores are based on is also open source, Gromacs.

i don't know if there is any discussion on making the folding cores open source.

I was wondering if there were any other people here with an Xavier. Nice to see I am not alone and that I came to the same conclusions as here. Since FAHClient detects the CUDA device, does it matter that it cannot detect the CPU on PCI-E? Why isn't identifying the CUDA device enough? I'm genuinely curious about this.

Of course, then there is the problem of FahCore_22 not having an aarch64 binary... :)

I doubt the Xavier is going to work with FAH but I don't understand exactly what it's intended to do. FAH does not use AI processing capabilities. It uses the compute capabilities of the geometry engine in a GPU. It's designed specifically to use the Floating Point resources of a CPU and/or GPUs. Those GPUs that are intended to do AI processing have resources that FAH does not need or use.

The Xavier is not a CPU nor a supported GPU.
