Nice work last month @axipher
I will not have my GPUs running 24/7 between now and the 19th. The BOINC Pentathlon has begun, and even though my team has gotten much smaller, I will be giving it all I've got. There will still be some folding time when my GPUs are not active. I'll be back to full time shortly after the 19th.

At least on Linux it's using the proper forward slash instead of the uncomfortable backslash.
PowerShell is crazy in that it will display the path "properly" on Linux, but you can do whatever you want from the command line. The aggressive path normalization can break all sorts of things in a mixed Unix/Windows environment.
From the command line these are all the same and the shell doesn't care:
PS /> gci -Path home/tictoc/temp/testing/powershell -i *`(1`)* -r | riPS /> gci -Path home\tictoc\temp\testing\powershell -i *`(1`)* -r | riPS /> gci -Path home\tictoc/temp\testing/powershell -i *`(1`)* -r | ri-

I imagine most of that performance lead evaporates against a 5995WX. IPC improvement of Zen 2 to Zen 3 is somewhere around 19% plus the higher stock clocks on a 5995WX.
The real question is how Sapphire Rapids Xeons will compare to current Milan-X CPUs and the Zen 4 Genoa chips. Depending on the workload, a 7773X is a pretty nice improvement over a 7763 (especially for a mid-process refresh), to say nothing of the upcoming Genoa chips and it's rumored monster L2 cache and 20% performance improvement.

Late to the show, but this is the kind of task that can be quickly accomplished from the CLI. More than likely this is what those GUI apps are using under the hood.
Since you're on windows we can use PowerShell with a few cmdlets. *Note* I am running this from PowerShell on Linux, but everything should be the same on Windows.
Here is a test scenario I created to accomplish this from the CLI.
List directories, sub-directories, and files in the current path:

The maximum number of threads is 32 threads per slot. To get around this maximum, you just need to use miultiple CPU slots. I'll quote myself from the other thread:
QuoteF@H works with threads rather than cores, so if you wanted to max out the system I would probably use three CPU folding slots, two slots at 20 and one at 26 (assuming you have a pair of 18core 36 thread CPUs in that machine). That will leave three full cores free, two to feed the GPUs and one for additional system overhead.

I really appreciate that. But I'm going to pass. They need to more clearly label the products being sold. If it's LGA 3647 or LGA 3647-1, that needs to be evident. I know I can get a new intel 3647 for around $400 from ebay, but I want dual socket. If I can find a dual socket model, I might keep everything and wait a few years to hop on it. But I don't think a dual socket board exists for the Phi. Hey, at least I learned a bunch from this.
I don't belive any dual socket boards ever hit the consumer market. Most of the high density Phi clusters were/are running on blades, so 4 boards/processors per 2U rack space.

Is folding@home able to take full advantage of the CPUs? How does that efficiency compare (GPU vs CPU)? reason being I do have a 24/7 rig I could fold with, dual procressor but weak GPU.
F@H will maximize CPU usage, but many of the simulations are highly parallelizable, so those calculations are more suited to GPUs. Once upon a time there were some very large tasks that were tailored to many core CPUs, but most of that work has been ported over to OpenMM to run on GPUs.
That being said, there are a number of projects that are CPU work only, and they are doing very interesting work. Here is a list of the currently active projects: https://apps.foldingathome.org/psummary The links in the project column will take you to a description of the project.
The OPENMM_22 core is GPU work, and GRO_A8 and GRO_A7 are CPU only. The CPU core has been optimized over the last 4-5 years, and now takes advantage of AVX instructions so it will put the CPU to work.

Kind of freaking out right now. I just read this
LGA 3647 - Wikipedia
EN.WIKIPEDIA.ORGApparently there are 2 versions of the P socket. But I have no way of knowing if the board that I bought is compatible with the Phi chips. Knowing my luck it wont be. I will find out tonight, but i'm kind of pissed that it's not easy to see.
X11DAi-N | Motherboards | Products | Super Micro Computer, Inc.
WWW.SUPERMICRO.COMThe board you linked (X11DAi-N) is socket P0 for Xeon Scalable-SP 1st and 2nd gen CPUs.
This is the only ATX form factor Supermicro board that I am aware of that supports Knight Landing. https://www.supermicro.com/products/motherboard/Xeon_Phi/K1SPE.cfm
There might be others, but I've never seen a working one in the wild other than the boards from the Supermicro and ASRock Rack developer workstations. I think Intel originally planned on Knight's Landing/Mill being compatible with all 3647 boards, but scrapped that plan when they EOL'd the Xeon Phi. I am pretty sure (but not positive) that you need a Xeon Phi specific board.

Okay I think everything is more or less sorted. @Avacadosorry about the temps in F!
The second CPU is slowly ramping up. The "CPU" portion is slowly creeping up in term s of CPU usage. I had not accounted for that in my last post.
So with fan settings on 3 out of 6 which is still pretty quiet I'm getting the following temps. But you are probably right once it fully ramps up CPU usage I will activate takeoff - go around power.
Right now cpus sitting at:
CPU0: 140*F
CPU1: 120*F
You can check core temp in the lower right corner and see I'm already pushing 290W
If you really want to put it through it's paces and fully utilize the CPU, I would add additionl CPU slots. F@H works with threads rather than cores, so if you wanted to max out the system I would probably use three CPU folding slots, two slots at 20 and one at 26 (assuming you have a pair of 18core 36 thread CPUs in that machine). That will leave three full cores free, two to feed the GPUs and one for additional system overhead.
The lastest F@H CPU core uses AVX, so expect a very heavy system load.

New front intake fan installed, and it moves a bunch more air than the Noctua.
Only two SATA SSDs left to mount, but I will need to make one more extension for the SATA power for those drives.

What am I looking at for an impact on performance with dual rank memory? I'm seeing 3-5% average improvement from a bit of research. In terms of bandwidth. Do two single rank modules work as like one dual rank module?
That is correct. Two single rank dimms per channel is effectively equal to one dual rank dimm per channel. With dual ranked dimms you would effectively be running quad rank if you populate all 8 slots, but generally speaking depending on the workload you will see a bump in performance.
I never really tuned my 2P v3 system, because I moved over to Threadripper shortly after acquiring it. The best performance on my Xeon v2 system, was using dual ranked dimms, but only installing 4 dimms per socket. My ASRock Rack board allowed me to bump the memory speed over the default for my sticks, so I was able to run 1333MHz sticks at 1866MHz. The board wasn't stable at 1866MHz with all 16 slots populated. Running in quad channel with 4 dimms per socket at the higher speed was the most performant setup, and I only moved away from that when I started to need more than 64GB of memory.

That's crazy. I've never broken blades off of a fan.
Don't worry about fan curves, servers are supposed to sound like jet engines.
The fan was spinning at 800 rpms when "someone" decided to put the front cover on the case, and might have inserted one of the cover standoffs directly into the path of the fan blades.
All the jet engines are going out to pasture, and I will basically end up with nearly the same overall performance and sweet whisper silence.

Octal rank is different than octal channel. Octal rank refers to the number of ranks per dimm. LRDIMMs generally come in quad rank and octal rank, which allows increased capacity per dimm. The increased capacity of LRDIMMs trades maximum capacity for performance.
In regards to whether or not it's octa channel, the platform itself (2 quad channel CPUs) technically has 8 channels, but each CPU can only address 4 channels locally. While the QPI is a fast path (8GT/s on Xeon v3) it's no where near as fast as local memory access. Generally speaking taking the performance hit is worth it due to the doubling of addressable memory.
Just saw your reply and that is all correct.
Specifically for your system the setup is good. The memory you have is single rank, so if you wanted to increase performance, you could look at getting some dual rank dimms which would bump up the memory throughput. For maximum performance anything above dual rank will generally be slower, and is only worth it if you actually need the additional capacity.

Actually it's still quad channel. Only Epyc, Threadripper Pro, and newer Xeon Gold/Platinum CPUs have 8-channel memory controllers.
Anything that is crossing the QPI to a far NUMA node, is going to suffer a hit in latency and performance. No idea how AIDA works, but in my experience, Windows generally tends to be less NUMA aware, so if the OS scheduler is not pinning processes to local memory then there will be a drop in performance.

After getting the 10 HDDs mounted, I decided to do some temperature testing to set the fan curve for the case fans. Had a derp moment while putting the front cover back on, and now I'll be installing a new front intake fan.
It might actually be a good thing, since I ordered a Silverstone AP183 which should push quite a bit more air than the Noctua.
I'll be cutting out all the unnecessary mounting points behind te fan which should help to increase airflow and reduce noise.

So that folding rig is at home two hours away, so I wont be able to fiddle with it physically for a little bit, but that definitely puts an idea in my head for a long-term solution. It's set up in an open top HAF XB right now, and I bet it wouldn't be too hard to rig up a small aluminum extrusion frame held on with some 3D printed brackets. Definitely something I'll look into for later.
Since you are running it in an open top bench, the easiest thing to do would be to rig up a fan or two directly above the GPU. This will force air down between the cards and add some fresh air for the intake of the top card. I've had lots of open bench machines running all out 24/7, and increasing the airflow directly to the top GPU will probably knock the temps down 10°C or so.

I picked up one of these chairs on a sale at Office Depot. https://www.officedepot.com/a/products/510830/WorkPro-Quantum-9000-Series-Ergonomic-MeshMesh/
Excellent chair for the price. After 5 years of daily 6+ hour use, it is still in like new conditon, with only some small cracking of the foam/rubber armrests. Pre-covid I think I paid something like $325, but even at $450 I would still buy it agin.

Went to Microcenter today, walked out with these.
5900x - $369.99 $179 below MSRP
6900xt $1,049.99 $50 over MSRP
It's weird that I paid over $1000 for a GPU that's $50 over MSRP and I feel like I got a good deal. But it's a hell of a deal for the CPU.
Great minds think alike.
Yesterday I went to look at a 2.5RS for a parts car. No dice on the car since the tranny was shot and the motor had a bunch of top end and bottom end racket. The local MicroCenter is more than an hour from my house, so I decided stop in and browse around for a bit while I was in the area.
I've had the block and backplate since they were released, and I was just waiting for a reference card at something close to MSRP.
21 hours ago, Sir Beregond said:Yeah, 5900X at sub $400 is a no brainer for sure!
As for GPU's, most of them seem to be getting very close to their MSRPs now. I know the Micro Center here has had AMD cards sitting on shelves for months now.
So looking at that box, is it a reference style 6900XT?
Yep reference 6900XT, and props to PowerColor for the minimal packaging. Last thing I need is another giant GPU box.

By default the AppData folder is hidden. Is it just the FAHClient folder that is missing, or can you not see your AppData folder at all?
You can also navigate to the AppData folder by pressing Winkey+R, and then typing %APPDATA% in the Run box.
