In this video we get a tour of the world's fastest super computers, Frontier and Summit, at @OakRidgeNationalLab! Both of these High Performance Computing (HPC) environments have played significant rolls in various areas of research.
Our tour guide, Daniel Pelfrey, Principal HPC Network Engineer, takes us through the challenges of Networking in an HPC environment, and some of them might surprise you!
A huge thank you to our friends at the Knoxville Technology Council for connecting us with the Oakridge National Laboratory.
Also, thank you to Kate and Daniel for the tour of ORNL, the super computers there, and for making this video possible!

@Alfred-Neuman 9 дней назад

It's not even "a" computer, it's basically just a botnet installed locally... The only difference I can see between this and a botnet it's this is installed inside a single room so they'll get better latency between the different RAM modules, CPUs and GPUs. What's I'm trying to say is this technology is not very impressing, they're using pretty much the same CPUs and GPUs that we are using in out cheap desktops. Just a lot of them...

@NorbertKasko 5 дней назад

@@Alfred-NeumanFor a while they used special processors in these systems, developed directly for them. Cray comes to the mind. When clock speeds become less scalable they started to use consumer hardware. In this they have 8.7 million processor cores instead of 16 or 64 (talking about high end desktop machines).

@chuckatkinsIII 10 дней назад

One of the coolest aspect of Frontier's network architecture is at the node level. Since all the compute is done on GPUs the network fabric connects directly to the GPUs instead of something like a PCIe bus. So simulations can transfer directly between GPU memory and the network fabric without involving the CPU or having to move data on or off the GPU to get to the network. It allows for incredibly efficient internode communication.

@noth606 10 дней назад

So the GPU's have NIC's connected directly to them? With some sort of second MMU with it's own NIC? It's a tad unclear from the way you describe it, but I wonder how it connects to the GPU since you say it's not using PCIe?

@chuckatkinsIII 10 дней назад

@@noth606 I slightly misspoke. The NICs use PCIe ESM but connected directly to a PCIe root complex on one of the GPUs. Each node has 4 GPUs each with 2 dies (so 8 visible GPUs) and a dedicated nic, so 4 NICs per node. Thus any CPU operation that has to use the fabric actually traverses one of the GPUs to get to a nic. Source: you can find a bunch of architecture docs for Frontier but I also worked for several years on developing some of the library and software stack for this machine and a few others that were just beginning to come online.

@alexanderahman4884 27 дней назад

Sorry for nitpicking but he got one thing wrong. The reason you don't use electrical network cables for longer distances is not primarily because of interference from the power cables but has all to do with attenuation. At these speeds it is very hard to get the signal more than a few meters, it will be heavily attenuated and very hard to distinguish a 1 from a 0. The solution to the problem is to use fibre optics instead.

Take note of the power cables for each rack, similar to the amount a large house might use, per rack. Removing the heat from those racks is a big part of the design. Air flows from the floor and out the top in active exhausts. A little hard to believe, but compactness is a top priority.

@artysanmobile 19 дней назад

@@mikepict9011 They have so much heat to get rid of, the concept of blowing cold air is no longer valid. Fluid is far more effective at conducting heat away from a metal structure and processors are manufactured with built-in liquid cooling. Each rack is built for purpose with an exchanger which takes it directly out of the room, then returns cold for the next batch. If you work on your home’s HVAC unit, you’re familiar. A widely distributed system like that can be monitored and adjusted for best efficiency.

No matter how big or small: The network IS the computer… For the past few decades, outside of embedded applications (and even in many situations there), computers have to be connected to a network to have any practical value; every piece of software, and most if not all its data, is sent over a network at some time in its lifecycle.

Not sure I understand the "noise" issue with copper Ethernet? It is transformer coupled at each end, self balancing with common mode induced noise rejection via the twist. I've seen it run around along with the wiring for 3 phase CNC equipment with no issues. Even at those scales I am not sure I buy that explanation. Length would be a real issue at that scale rather than noise I would have thought.

You know if they switched off all those small diodes on each server, blinking all the time, consuming power, I wonder how many watts that is total. You really only need those lights to debug if something is working right? could be a little switch instead to toggle those on and off

@sky173 10 дней назад

You can think of five L.E.D.s using about 1 watt of power. In the grand scheme of things, If they were switched off, most people would not know that some energy was saved. If you look at the home computer, it's costs (on average) $35-$40+/- a year to run a home computer 8 hours a day for one year (possibly much less). Those same five LEDs (diodes) that you mentioned would cost 35-40 cents to run them 8 hours a day for a full year (or just over a dollar per year if running 24/7)

In all seriousness, not very well. Games have such miniscule latency requirements that any distributed system is immediately going to fall on its face. Even chiplet-to-chiplet within the same CPU package has proven to be enough to affect game experience - reviews of the R9 7950X all identified that frame pacing was affected dramatically when threads moved between CCDs, let alone moving between entire racks. Now, playing Crysis on a single unit, especially if it has both CPU and GPU compute...
