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...

Biggest difference between HPC networks and corporate networks is lack of security in favor of performance at all costs. The compute nodes directly access remote memory over the network RoCE

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.

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

@@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.

Great video. Thanks for taking us along with you all!

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.

Granted this is a 'network' overview. Go read about MPI. Swear a lot. And it will start to come together. Jobs that run on systems like this can run on hundreds of nodes at the same time. It's at all impossible. And yes, they can run containers if you wanted to do so.

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.
