Not my last purchase, but one I purchased quite a while ago, that showed up on my front porch today. First order of business will be taking care of those nasty Windows keys Unicomp Mini M

I've been out since the beginning of the month (BOINC Pentathlon), but I'll have some gear back up an folding later this week.

Everything is up and running, and it will be getting a two week long stress test with the CPU and GPUs running 24/7, all out, for the BOINC Pentathlon. Setting up the whole software stack for the server will have to wait, so for now it's just running a minimal headless Arch setup for crunching.

I think one of the bigger problems is that a large percentage of "media" companies are owned or run by the companies that are actually delivering the media. This is especially a problem when there are large swathes of the US outside of major cities that only have one or maybe two options for internet/TV service. Companies like Comcast, AT&T, Verizon, and Charter are able to leverage their infrastructure to prop up their own media companies. This requires an obscene amount of oversight, since it would be easy for the companies that deliver the media to push the scales to favor their own in house media companies.

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.

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 | ri PS /> gci -Path home\tictoc\temp\testing\powershell -i *`(1`)* -r | ri PS /> 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: List all the files with "(1)" somewhere in the middle of the file name.

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:

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.

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.

The board you linked (X11DAi-N) is socket P0 for Xeon Scalable-SP 1st and 2nd gen CPUs. x11dai-n_quickRef.pdf 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.

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.

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.
