      aiGeis why would you expect a professor of plasma, energy, and radiology to know about computers? The two fields are pretty separate. Also it’s not like it’s a usual commonplace board, it’s the highest end of computer products, if you were able to inspect all the components I’m sure you would get things wrong too unless your a specialist in the field.

    I have recently started watching this channel and I love the content presented here. So before I make my comment let me begin by saying thank you for sharing this!
    Now I just want to point out that during the clip at 11:58 you begin to explain what the blade is for the super computer and while most of the information was correct there were a couple huge parts that were not correct. First all of the black thin blade like wafers you pointed out being processors are in fact the RAM not the processors and the heat sinks (the copper finned areas) are in fact where the processors are and this particular server blade has 8 physical CPU cores each with its own heat sink two of which have been removed, showing the mounting bracket below which are the silver squares in between the two copper heat sinks in the middle to the left. The silver heat sinks in the middle are heat sinks for board components and not memory aka RAM as you pointed. That again is the black blades to the left and right of the copper heat sinks.
    Again you do fantastic work and I love your content so keep it coming. I just wanted to point that out to avoid confusion and make sure the correct data was presented so people were not confused and mislead.
    Thank you!

    The nice things about datafloors is that you can just take out the tiles if you need to add new infrastructure and/or rack units. This floor may look large and it is for just one (collective) machine. But many datacenters (which hold conventional multi-purpose servers) have multiple of these floors which hold a ton more servers and are mostly connected to the ISP network and routed out to their respective paths.

    In my understanding computers generally get expanded in a parallel manner, because their clock speeds are fixed to around 5Ghz as it stands. So that is ok for applications that can be done at the same time, but if new tasks require the output of a former stage, the process stalls. 12:38 the stuff in the middle looks like 2 unpopulated cpu sockets without the heatsinks, the stuff on the left looks like memory, and the stuff on the right looks like voltage regulation.

      @WarrenGarabrandt 5 лет назад

      Computation is "free", as in, it doesn't cost any energy or generate any heat. Your computer actually only generates heat in the CPU when it has to force a transistor to clear its value, to reset for another computation. This is mostly why your CPU doesn't really use much electricity or generate much heat when it's idle, but can use an order of magnitude more power and produce an order of magnitude more heat when it's actually doing something like playing a game. The evicting of information from memory (including the states of transistors used in computations) removes information from the computer and radiates it out as heat. Information isn't destroyed, it is radiated away as heat, increasing the entropy of the universe.
      With that in mind, there is actually a lower limit to how much power and heat a computer can use/release at a minimum for a certain amount of work. Unfortunately, the lower limit for 13 petaflops of computational power is well beyond a coin cell and a matchbox sized heat radiator. But I do get where you're coming from.
      We had computers in the 60s that were so amazingly inefficient that with technology advances we now have phones with orders of magnitude more processing power. We will certainly get faster and more efficient computers in the future. I doubt we'll ever get a desktop PC with that much processing power, at least not so long as we are using silicon transistors.

  • @coorbin
    @coorbin 5 лет назад +1

    13 petaflops really isn't that impressive, and you wouldn't need "millions" of laptops to equal the raw FLOPS of that supercomputer. A teraflop of computing power on a GPU costs about $50 in 2019, factoring in the cost of the rest of the system (RAM, CPU, etc.) and that's 1/1000 of a petaflop. So if you had the energy and space to run it, you could slap together 13 petaflops with $650,000 or so. Real supercomputers cost a lot more because they're a bit more space-efficient than putting together thousands of desktop systems, and there are very expensive, high speed interconnects between the different parts. For embarrassingly parallel algorithms that require little to no communication between the various parts, though, you wouldn't need those expensive interconnects, and could just use a bunch of independent systems.

      So sure, your GPU offers several dozen Teraflops of capacity. But definitely not your CPU, which runs at Ghz*Cores*Ops/Clock (8 Double-Precision FLOP/cycle for Ryzen 8, up to 32 on some high-end Intel). So even with a 64 core Ryzen at 4Ghz, you’d need 500 per petaflop to equal that performance.
      Also the GPUs often only have those rates when you do single precision (32 bit) floats, when most scientific computing demands double or sometimes even quad precision. And those often get slower exponentially, not linearly.

    I believe that the way to our Creator is appreciation (child heart wonder) of the capacity humans have to create amazing things. There comes a transcendent moment, when we are sincerely amazed, that we have an opportunity to open our heart to what I believe is the Spirit of God speaking to us.

    Pointing at RAM. "These are the CPU's"…
    The CPU's are under the "pink" heatsinks. You can see the socket on one, and the CPU on the other one where there's no heatsink.
    "These are the memory." Those are NVMe drives for storage.

      You are right there are not ram. But they arent storage either. Voltage Regulation Modules. Each CPU has its own power supply that is a field replaceable unit. Hence the Beefy Heatsinks and being in the hot section. These blades have no storage. Everything is netbooted over the infiniband and storage is handled by master nodes.

    I gotta say, these how things work videos don't really match the high standard you set with your excellent whiteboard videos on fission and energy economics. This doesnt really answer any questions about what makes a supercomputer different from a regular computer, or how they can split up a problem to thread it efficiently on thousands of processors, or how the system synchronizes physically quite distant components or moves data between them

    • @khufure
      @khufure 3 года назад

      the splitting up of problem answer actually makes your synchronize data question redundant. splitting up the problem into manageable slices eliminates the need for all the components to know the answer. the splice of data output each component works on will be uploaded to storage.

      nothing about the hardware of a supercomputer is that special other than in some cases networking (theres rare examples like intel xeon phi) the special part is networking and the software that allows thousands or tens of thousands of nodes to work problems.

      ​@@uploadJ you don't need a manual, you can literally see it. You can clearly see near the middle where 2 copper heatsinks have been removed there is an empty CPU socket and a socket with a CPU in it. What he pointed to as the CPU rows are clearly RAM DIMMs and what he pointed at in the middle calling RAM look like slot mounted VRMs.
