I understand this pruning is the difference between "silicon"and "software-assisted" TOPS in their documentation but I still don't see how exactly that's going to address the fact that to fit a 30B parameters model into memory, you need at least that. So basically to go 30B and up, you would need at least two, if not three cards and I couldn't find any details on how interlink is going to be implemented except that it's apparently done via Ethernet, limiting it to 100 Gbps which again, seems like a hard bandwidth limitation out-of-place when comparing it to impressive compute. Also: "online installer required" is not a good look, at least for me personally and the security model of my system. AMD cards, however, are affordable commodity hardware, offering 32GB HBM2 and the driver is open source so I wouldn't really discount it even considering their lacklustre performance. Cloud VMs do away nicely for most use-cases but as long as soon as hard security comes into focus, you just can't afford to have unauditable blobs from NVIDIA, or any other vendor for that matter. I'm still looking forward to learn more about Grayskull, especially on its memory capacity/bandwidth limitations and what it means for ever-growing large language models. Hopefully, they can open-source their driver stack.
- VHRanger 4y agoNotice they require 32gb RAM and encourage 64gb RAM. Presumably the architecture keeps the model in CPU RAM and shuffles it dynamically to the PCIe card network? I'm guessing here. Whatever quirks come out of their hardware, I want to keep an eye on it. I also think that comparing the current generation of models, which are built and trained to maximize GPU or TPU bandwidth, could be improved if someone architected models to maximize their model to greyskull advantages. Given PyTorch runs on it, I don't think it'd be too hard to do.
