Optimize GPU vs CPU

[Pellicle]

Question
I have a Ryzen &3800 system with a AMD RX 590 GPU.
The system is currently dedicated to folding@home
I noticed when both GPU and CPU are running loads sometines the GPU utilization drops significantly. If I pause the CPU the utilization of the GPU will increase significantly.
The CPU when running typically is showing all cores loaded to 100% and running at full frequency.
I tried an experiment to free up one core and this results in the GPU utilization being increased to near maximum and the CPU.
It appears to me that this is resulting in more units processed for a given time since the GPU output is maximized with a slight degradation to the CPU.
I am assuming the GPU is being throttled by not having enough CPU capacity devoted to feeding it.
Is this a reasonable strategy to maximize. I have not been using folding@home for long and am looking to maximize contribution of my system to the project.
Input would be appreciated.

If you post you log inc the first 200 lines or so with the system configuration someone may be able to more accurately advise … viewtopic.php?f=61&t=26036.

You do need at least one CPU thread to service the GPU.

Below is an excerpt from the log for perusal.
Thank you for your feedback and assistance.

Welcome to Folding@Home!

You did not include the first 200 lines so some advice is fragmentary.

Set your number of threads to 12 (F@H calls them CPUs)

You have 16 threads but F@H reserves one for feeding the GPU.
That leaves you 15, but F@H hates large Primes and their multiples, it is safest to only use numbers with 2 and 3 as factors.

15 is 3 * 5, so F@H dislikes it
14 is 2* 7 so F@H dislikes it
13 is Prime, so F@H dislikes it
12 is 2*2*3 so it is ideal

In the taskbar to the lower right of the screen, you should see a F@H molecule icon, click it (you may need to click an Up Arrow to see it ^)

The second item in this menu is Advanced Control, click it

On this screen to the left is a Configure button, click it

Now you get a screen with a Slots tab, click it

On this white field should be a cpu item, click it and then click edit

By default F@H set the number of CPUs to -1 meaning let the software decide.

Type the number you want, and click save.

Then capture a new log and show us that.

viewtopic.php?f=24&t=26036

I hope this helps!

FAH does want 1 thread (logical core) reserved for the GPU. If I'm not mistaking, your processor got 8 physical cores and 16 logical cores / threads. Therefore the standard setting in the CPU slot settings would be -1.
Otherwise you can define 15 "cores" in the cpu slot settings, to ensure the 16th is available for the GPU. If I read your log correctly, you have defined 14 CPU cores for FAH. You might run into trouble with that, since FAH doesn't like multiples of larger primes, such as 7 and onwards. Best is to stick to core counts which are multiples of 2 and / or 3. 5 is apparently still an acceptable factor, too. You might be better off with 15 or 12 cores or make 2 CPU slots with 9 and 6 cores respectively.

Thanks to both JimboPalmer and HugoNotte,
BY trial and error I saw that when I set to 14 threads the CPU utilization decreased. Cores 5 through 8 showed decreased utilization running significantly lower in frequency.
But the GPU was running at a higher utilization than the default settings.
I increased threads allocated to 15 and the CPU utilization went back to full utilization with all cores running at max with corresponding power and heat increases. However I am seeing decreased GPU utilization again. So I have set CPU core allocation to 13. GPU now is running at higher utilization >90% as opposed to around 70%.
Assuming my system readings are a reflection of output rate from F@H I am thinking this might be a good compromise. If my assessment is incorrect please comment.
Attached is full log after change

[HaloJones]

when you set it to 15, you may be dedicating what FAH thinks is a core to the GPU but you're really only dedicating half an actual hardware core.

try it with 12 as suggested. I think it will give the best mix.

[Neil-B]

You may well have issues with a 13 slot as it is a prime number … better might be a 12 slot (highest count you can get that isn't likely to have issues and gets science done fastest and a 2nd slot with 2 or 3 depending on what suits your kit best and keeps the GPU happy.

[Pellicle]

Have set to 12 and 2 CPU threads using 2 slots.
Seems to be best again assuming utilization as shown by the system metrics is a refection of output.
Attached is full log.
Thanks for your input and help.

Please note that while the configuration has 13 CPUs in it, FahCore will automatically change it to 12. It would be better to simply change it to 12 in FAHControl to stop that message form being written. Also, you have a single CPU Slot using 12 CPUs and a GPU slot. I am not sure what you mean by "2 CPU threads using 2 slots"

I would say that this is the optimal setup. Sure you may have 3 CPUs unused but I won't suggest adding another CPU slot since folding performance is largely impacted by the physical cores which in this case are fully used. HT/SMT does provide an increased benefit but isn't as good as physical ones.

[Pellicle]

I have set 2 GPU slots
One with 12 threads and one with 2 threads
My CPU has 8 cores and 16 thread capability.
Not sure why the reduced count message unless log was not cleared when I reset the configuration.
Reverified setup in config is as noted above
The reason I am splitting the 1 physical CPU to 2 slots is to increase utilization of the GPU which seems to be limited when all 16 CPUs are in one slot.
I know that 1 is reserved to service the GPU but what I am observing is the GPU is waiting for the CPU to "load" it.
This is not a thermal throttling issue as both are cool and not throttled.
When I reduce Cores allocated to the CPU the GPU utilization increases significantly.
So the thought was to manually assign core counts. Adhere to the Prime number limitation and set 12 and 2 leaving 2 free. If there were not issues with prime I would set to 14 or 15 but have been advised against this.
Running this way I seem to be getting more utilization from the GPU which is more efficient a number crunching while sacrificing 1 thread of CPU capacity.
I am open to any input on the best way to optimize but default does not seem to be as effective in my system to maximize GPU output.
Alternate ideas welcome.

[PantherX]

I understand your POV to have a system that fully utilized. However, there are two options:

Option 1 - Best utilization with maximum scientific contribution
You will have 1 CPU Slot with 12 CPUs assigned to it.
You will have 1 GPU Slot for your GPU.
You will notice that the overall system usage will be; CPU around 75% with bursts to 100% (this happens when the GPU writes checkpoints), GPU around 90% or higher.
The reason is that F@H desires that WUs are returned as quickly as possible. It isn't about the number of WUs your system can fold simultaneously, instead, it is about how quickly an assigned WU your system folds.

Option 2 - Highest utilization with negative impact on scientific contribution
You will have a CPU Slot with 12 CPUs assigned to it.
You will have another CPU Slot with 3 CPUs assigned to it.
You will have a GPU Slot for your GPU.
You will notice that the overall system usage will be; CPU around 94% with bursts to 100% (this happens when the GPU writes checkpoints), GPU around 90% or higher.
The reason this has a negative impact on scientific contribution is because your CPU is processing 2 WUs, not 1 thus, there's resource contention.

Please note that while you may have 16 threads, it is the physical 8 cores that folding fully utilize. The SMT/HT does provide some additional gains but not comparable to a physical core. Feel free to post your current configuration if you would like any additional clarification

[kiore]

I am running a similar rig but a Ryzen 3700x rather than a 3800 but still 8/16 cores, I am using what was recommended CPU=12 and the rest for the GPU which is giving me the best output for the project CPU wise without throttling the GPU which in windows needs one core/thread assigned and at times uses some more resources for checking. I know that it seems I am wasting 3 cores but overall this works better. You can experiment the mix yourself but you have received (above) good advice from people who know how this project uses resources.

[Neil-B]

To further expand the discussion to try and clarify my own understanding about resource contention:

As a matter of interest where does the resource contention break even? .. I haven't noticed significant (although I haven't looked too hard) differences in the PPD of either of my slots (32/56 and 24/56) when the other isn't folding (which is relatively rare) ... and I guess dropping the 24/56 might not be best for science as I would hope that the extra value of the 24/56 slot outweighs the relatively (from what I have seen) minimal impact from an resource contention ... but is there any rule of thumb? ... should a 2nd CPU slot only be used when say it is 4core, or 6core, or 8core? ... does the amount of contention vary dependant upon how many spare cores there are? ... is CPU slot to CPU slot resource contention as much of an issue as CPU slot to GPU slot resource contention? ... and I would guess it might also be reasonably kit dependant - would a multi CPU Xeon server handle CPU slot to CPU slot resource contention in a nicer manner than say a single CPU desktop/laptop? ... does the OS play into this Linux vs Win, Desktop vs Server? ... and type of CPU - Do Xeons handle multi-threaded cores more efficiently than hyperthreading - Is there an AMD equivalent of this?

I guess there won't be a simple answers to a few of the above questions - and any rule of thumb might be a bit long and have caveats - but hey, this is an interesting area of complexity that probably impacts most folders setups and an attempt at coalescing some answers in this thread will provide a reference thread when this topic next comes up ... as I couldn't find any previous thread with much more than passing mention.

AFAIK, FahCores are not NUMA aware simply because at that time, multi-socket systems were not common. Fast forward a decade, Threadripper has used infinity fabric for HEDT. At this stage, I am unsure if FahCore will adapt to it or not. Moreover importantly, will Windows adapt to it or not since that could pay a part in adding those features to a future version of FahCore.

2 CPU slots "fighting" over a single CPU would be a higher resource contention then a CPU and GPU slot fighting over it. My rational is that CPU folding requires AVX instruction sets whereas the GPU just needs data and sanity checks every X% but it is sensitive to contention as GPUs are really fast. Hence, an interruption to data streaming from the CPU will cause the GPU usage to plummet.

If anyone is keen to test, see what the TPF is when using only physical cores and then physical plus virtual cores. The last time I did that on an i7-860, I found that I had about 12% to 23% reduction in TPF when I went from 4 physical cores to 8 CPUs so not the 50% reduction that one may expect when moving from 4 CPUs to 8 CPUs. For this usage, I suggest TPF rather than PPD as I am keen on seeing how the performance of the WU maps out as opposed to the change in PPD.
