We did a video on both Intel GNR-AP and the new EPYC Turin. Intel's GNR-AP now can be ahead of EPYC. Still, these would need well over 300 PCIe Gen5 lanes in a server, and even that is not the right answer for P2P communication. You also get more channels with both, but due to their physical size, you lose DIMM slots making memory capacity a challenge.
@levygaming3133
@levygaming3133 Күн бұрын
What on earth could this server possibly be doing that could need more _cores?_ Like, I’d just assume that because the whole point of the server is all those GPUs, you’d get something CPU-wise that’s just got the minimum number of cores to get the memory channels and PCIe lanes you actually want. But I’ve got less than no experience buying servers, closest thing is I’ve been eyeing an HP mini pc.

I recall that the power surge issue is so serious on Ampere GPUs that we ended up upgradeing the PSU on our servers. AI/DL loads typically just takes forever to preprocess (read, parse, and pack as batches) the dataset to GPU VRAM and the GPU will crush the computation and draw insane amount of power that triggers OCP on PSUs.

But will it run Crysis? OK. Joking aside I was going to ask a question about how much more inference can be done on those GPU's vs training (it is my understanding that Inference is much lighter task), but then I noticed that you said about this power spikes and how utilization will go from 0 to 100 and to 0 again. Is this because of training algorithm? Is it inefficient? Or maybe something else is bottlenecking the system? And since you mentioned that this happens over and over - are we talking several times a minute or hundreds time a second? And if we graphed the GPU use over time, what would be the "average" GPU use? Because it seems tad inefficient if it works just "from time to time". Thx for the video. I wish I had slept pass 2 nights, maybe I would understand more ;)

Training to date has been mostly NVIDIA HGX platforms like this. The quick version of what happens is the GPU gets sent a job, does a lot of math, then has to send the results out and wait for the aggregation to get its next job. You are right, that can be inefficient which is why folks are using so many 400G NICs

Usually you train in many epochs. Each epoch runs many iterations on the same data and keeps GPU 100% busy because no time wasted moving data. Once epoch is done it will fetch new batch of data and you’ll see small drop of utilisation to 0 and back up to 100. But this happens very fast in a second or so. One epoch can take couple minutes but it all depends. Inference is similar intensity as training, you are just only doing forward pass without back pass. In fact inference can be optimised to use more of hardware and load it even more removing less parallel steps or bottlenecks.

For the OP: an 8x L40 server seems to be ~180k-200k, with ‘Hopper’ HBM equipped GPUs like this has being more than that, and the current rumors are a half million for 8x Blackwell HBM server, and either 1.5 million or 15 million for one of those 72x Grace-Blackwell “SuperChip” racks.

As someone that loves to learn and also loves hardware I have taken a fascination with llm's. The problem is that there is so much data and stale data on what makes since. For the most part llm craves vram above all else but there are so many nuances there. I am currently looking at ditching my four 4070 supers in favor of MI100 cards as they can be had for just over a thousand dollars these days but finding reliable data is so hard.

I these supercomputing racks, I always wanted to know if all the RAM does get used? I know that some computations or when training AI can take weeks or even longer with all these chips running flat out. non stop. I guess the dataset gets loaded into memory. But DAMN that is a lot of data if its filling all the ram on very node - and there are hundreds of full server racks top to bottom stuffed with the H200s. What storage do these things have as well? It's never as impressive when they're showing off cutting edge tech to talk about all the empty space there is ! But the big datasets music be stored somewhere before being read into RAM so I have to assume it's a boat load of SSDs with decent read/write speed. Question... if data is read from the SSD but is required to be in RAM on every rack. Does the RAM copy what its read to other racks RAM to RAM, or does it have to continually read off the SSD until it's done it enough times to fill all the racks's and their RAM on each multi-GPU platform?

Yeah, I’m pretty sure that the cores are completely unchanged between the two, and the only difference is more, faster, and newer HBM memory. I think the H200s even have an extra HBM site active at 6/6 instead of 5/6 on the H100s. And so every benchmark where you see performance uplifts between the two is purely showing off the advantage of more bandwidth. At least, that was “The Next Platform”’s conclusion.

Would be a fun one to test, I think if you ran crysis on something like this it would be the highest viewed video on tech youtube for the month, although I imagine there might be other blocking issues with getting that running.

@@ICanDoThatToo2 so, that’s an interesting concept: On the one hand, people have already benchmarked these GPUs in games (well really TimeSpy) and the performance was really bad, like if you have any GPU that’s in the Steam hardware survey it’d be faster bad. Also, one of the major benefits of this GPU is the ludicrous amounts of VRAM bandwidth it has, which is moreso an advantage at higher resolutions, which a cloud gaming setup wouldn’t use. On the other hand, this has so much VRAM and VRAM bandwidth that you could split it up 10-12 ways _per_ _GPU_ and still have a decent GPU, and this is one of the more expensive GPUs where NVidia officially supports and endorses splitting up GPUs. I’d love to see a cross between these reticle limit GPUs with all the HBM and a 4090 style gpu.

16:21 that's the problem when using multiple cards for AI training/inferencing. The GPUs are simply working sequentially at a fraction of their potential, the customers forced to dump loads of cash and buy all eight H200 to get a total of 1TB GPU memory. A single H200 with theoretical 1TB of GPU RAM in that scenario will deliver the same performance as all those eight H200.

Not necessarily. There are multiple types of parallelism that each have their own characteristics and scale with a larger number of GPUs in their own unique ways. Tensor parallelism takes advantage of a feature of matrix multiplication. If you look at the product of the first row or column of two matrices, it’s not related to the product of the second column in any useful way. In other words, you can throw half the columns on one GPU and half on the other. This scales really well and has low bandwidth, but operations which require an all-reduce (ie: Attention’s softmax) reduce performance heavily. There’s a practical limit on tensor parallelism to around 4-8 GPUs in my experience (though I don’t use systems with proprietary interconnects between accelerators), but it does more or less perfectly pool together the memory capacity, bandwidth, and compute of the GPUs (or CPUs!) used. Pipeline parallelism puts a number of layers on one device, and a number of layers on the next, and the next, and so on. It generally uses more bandwidth from my experience than TP, but it’s a lot simpler to program and optimize. Performance depends on the topology, and the use case. If you’re doing large inference batches (ie: serving customers), or doing offline processing of large amounts of data (ie: agents, document retrieval, etc), you can actually hide the “bubble” where you don’t have many overlapped computations, leading to pretty close to “perfect” scaling, if bandwidth allows. This is more scalable than tensor parallelism, but it doesn’t improve response latency usually. It still gives you more tokens per second, but not necessarily a “faster” response in all situations. It does use “all the GPUs”, though, and gives you more memory capacity from the model. Data parallelism is the final one, and at inference it sort of scales perfectly, insofar as anything does, but it does mean that you’re running a unique instance of an LLM / CNN on each node, so the responses of individual sessions aren’t accelerated. There’s also multidimensional parallelism which can combine properties of each of these. Regardless, you can actually scale the usage of GPUs networked together a lot better than you’d think, and “use all of them together”, because the operations behind AI models are very parallel by nature.

@@novantha1 Thanks, that was helpful. One note though, I'm far from being an expert in the area, but tensor parallelism you mentioned doesn't seem to dominate the computation in AI workloads as I have never observed the saturation of the GPU cores in multi GPU configurations. In fact, I'm always noticing a proportional reduction in GPU usage with the increase of GPU cards during the AI workloads.

@ Yup, it doesn’t matter which parallelism you use; there’s always overhead, it’s just you pick the overhead you can live with. My experience is generally on small scale installations using consumer hardware, so it’s a bit coloured by that (with 8 nodes, a 2 GPU TP, 2 TP pipeline, 2 data parallel structure feels pretty lossless), but as you get to larger models, larger workloads possibly spread across more datacenters the math gets very different. Your performance per GPU isn’t quite logarithmic, but it definitely feels like you lose around 0.5-1% per GPU you add to the system as long as you’re using the right parallelism. As for why Tensor parallel doesn’t dominate in the industry? The softmax operation, lol. It’s a real killer in larger deployments, even if it doesn’t matter in 2 GPU, or 4 GPU configs that much. I think there’s an argument for multi-dimensional parallelism at such scales, where you use multiple types (ie: you make pipelines of tensor parallel configs), but not all software is built to support that, and it’s not like everyone has experience with, say, PyTorch Titan’s asynchronous tensor parallel, for instance. I listed it first because it’s quite dear to my heart and is often more useful to end consumers who want to run AI applications, though (because you get less latency for a single response, in contrast with the other parallels). It’s also worth noting that for architectures without a softmax (linear attention, RNNs, etc), you can get going *pretty* fast with enough GPUs. Right tool for the job, and everything.

@@novantha1 oh, I wasn't talking about 0.5-1% per GPU. Take two GPUs (regardless, consumer or for datacenters) and do some AI inferencing with any model, you'll see the GPU usage dropping to just 50% per unit. Take four GPUs, and the usage will drop to aprox. 25% each. And in this video I observe exact the same behavior. I thought memory bandwidth is the cause, but no, H200 is huge and behaving the same. My current understanding is the AI software accessing the GPUs sequentially, the algorithms are not optimized for concurrent GPU usage.

GPU memory is not always a limiting factor. For workloads I run I usually run out of compute on GPU before I run out of memory (for inference). For training you can set high batch size and also cache data on GPU and use all memory. For inference I’m limited by processing power, not memory. I run on RTX 6000 Ada 48Gb, not these monsters but same balance applies. You mostly need lots of memory for LLMs and such.

Idk, I do machine learning on a 40 node cluster, on prem. But managing the hardware is not worth the effort. I've been looking to move to cloud so I don't have to worry about hardware again. I know, 2.4x the cost for cloud verse on prem. But when cash flow surpasses the 2.4x then it's time to move to cloud. I'm tired of managing the hardware.
