Re: Smoke and Mirrors
I've got multiple custom-PCB 16-Socket versions (YES! Sixteen CPU Sockets!) of AMD Ryzen 2700u, 16-socet Threadripper-2, ...AND... 16 socket AMD EPYC motherboards sitting on my workbench NOW! It took me less than three months to design, print and test ALL THREE!
We were the ones who developed and printed ALL the PCB's at our facility. (we use these boards for Aerospace-oriented synthetic vision system and various grid-processing tasks) And you are correct in that the EPYC architecture DOES NOT ALLOW for the direct connect of four CPU's like the old Opteron AbuDhabi's did. So we basically made 8 separate EPYC server boards onto ONE very large PCB and interconnected then with an onboard 100 gigabit switching network (i.e. single mode glass fibre). We did the SAME for the Threadripper-2 and Ryzen-2700u's making them independent micro-motherboards but printed onto a single PCB all interconnected with an onboard 10 Gigabit switching network. For multiprocessing, we've got our ULTRA-POWERFUL grid-processing software which automatically load-balances all the available CPU's!
Software-wise, we basically run a grid-based Linux OS on each set of processors, but if you want, you can also directly run Windows 2010, Ubuntu or Mint or Windows 2016/2019 Server as if they were regular separate motherboards. We actually did this multi-CPU on single PCBs since the days of 80286's, 80386's, MC68040's, i860's, SuperSparcs, MIPS, Pentiums, AMD Opteron AbuDhabi's, and now we do it with Ryzen- 2700u, Threadripper-2 and EPYC chips for cost reasons.
We've done this multi-CPU-on-a-single-PCB method FOR DECADES NOW !!!
You have to remember, the parent company has ENORMOUS technological personnel and engineering resources behind them! They can AFFORD to do this type of completely custom work! This company has LITERALLY TONNES OF RACKS of these 16-socket boards in the main warehouse! AND this company also does supercomputing-oriented design and manufacture of combined CPU/GPU chips for 128-bits wide Array processors for advanced bitwise and higher-level Fixed Point, Floating Point and Integer math operations and digital signal processing. These chips are printed on GaN and GaAs and run at 60 GHz clock speeds so this company has better technology processes and systems than Apple, IBM, Intel, AMD and ARM ALL-COMBINED !!!
This company is on par with the super-secretive "Black Budget" divisions of Lockheed Martin, Boeing, Raytheon, Northrup, etc.
I would say they literally have "Alien Technology" that is WAAAAAAAAY BEYOND what you can get on the open market!
AND...it kinda helps i'm personal friends with "The Boss" since the early days....so I get a lot of FREE access and use of high technology that very few others get to ever see and use in exchange for some friendly as-a-personal-favour custom PCB design and low-level systems programming work! I would say THAT'S NOT TOO BAD for a guy who merely has a Television Production and VideoGraphics Diploma from SAIT!
