We are very proud to announce the world's first and only Nvidia GH200 Grace-Hopper Superchip and Nvidia GB200 Grace-Blackwell Superchip-powered NV-linked, liquid-cooled, CDU-integrated, ready-to-use, "small-sized" rack server systems. Multiple NV-linked GH200 or GB200 act as a single giant GPU (CPU-GPU superchip) with one single giant coherent memory pool. We are the only ones who offer also smaller systems than a complete rack (with "only" 4, 8, 16 or 18 superchips). If you like AMD, we offer Mi300 systems too. All systems have a coolant distribution unit (CDU) integrated into the rack, are ready-to-use and are perfect for inferencing insanely huge LLMs, quick fine-tuning and training of LLMs.

Example use case 1: Inferencing Llama 3 400B
  • Info:
  • Llama 3 400B (to be released) will be the most powerful open-source model by far.
  • Llama 3 400B needs at least 800GB of memory to swiftly run inference! Luckily, GH200 NVL/GB200 NVL have up to 20TB/30TB. One rack of Mi300A or Mi300X has up to 8TB.
  • Example use case 2: Fine-tuning Llama-3-70B with PyTorch FSDP and Q-Lora
  • Tutorial:
  • Models need to be fine-tuned on your data to unlock the full potential of the model. But efficiently fine-tuning bigger models like Llama 3 70B remained a challenge until now. This blog post walks you through how to fine-tune Llama 3 using PyTorch FSDP and Q-Lora with the help of Hugging Face TRL, Transformers, peft & datasets.
  • Fine-tuning Llama-3-70B within a reasonable time requires special and beefy hardware! Luckily, multiple GH200, GB200 or Mi300 are ideal to complete this task extremely quickly.
  • Example use case 3: Creating a Large Language Model from scratch
  • Tutorial:
  • Imagine stepping into the world of language models as a painter stepping in front of a blank canvas. The canvas here is the vast potential of Natural Language Processing (NLP), and your paintbrush is the understanding of Large Language Models (LLMs). This article aims to guide you, a data practitioner new to NLP, in creating your first Large Language Model from scratch, focusing on the Transformer architecture and utilizing TensorFlow and Keras.
  • Taining a LLM from scratch within a reasonable time requires special and extremely beefy hardware! Luckily, multiple GH200, GB200 or Mi300 are ideal for this task.
  • Why should you buy your own hardware?
  • "You'll own nothing and you'll be happy?" No!!! Never should you bow to Satan and rent stuff that you can own. In other areas, renting stuff that you can own is very uncool and uncommon. Or would you prefer to rent "your" car instead of owning it? Most people prefer to own their car, because it's much cheaper, it's an asset that has value and it makes the owner proud and happy. The same is true for compute infrastructure.
  • Even more so, because data and compute infrastructure are of great value and importance and are preferably kept on premises, not only for privacy reasons but also to keep control and mitigate risks. If somebody else has your data and your compute infrastructure you are in big trouble.
  • Speed, latency and ease-of-use are also much better when you have direct physical access to your stuff.
  • With respect to AI and specifically LLMs there is another very important aspect. The first thing big tech taught their closed-source LLMs was to be "politically correct" (lie) and implement guardrails, "safety" and censorship to such an extent that the usefulness of these LLMs is severely limited. Luckily, the (open-source) tools are out there to build and tune AI that is really intelligent and really useful. But first, you need your own hardware to run it on.

  • What are the main benefits of GH200 Grace-Hopper and GB200 Grace-Blackwell?
  • They have enough memory to run, tune and train the biggest LLMs currently available.
  • Their performance in every regard is almost unreal (up to 8520 times faster than x86).
  • There are no alternative systems with the same amount of memory.
  • Ideal for AI, especially inferencing, fine-tuning and training of LLMs.
  • Multiple NV-linked GH200 or GB200 act as a single giant GPU.
  • Optimized for memory-intensive AI and HPC performance.
  • Ideal for HPC applications like, e.g. vector databases.
  • Easily customizable, upgradable and repairable.
  • Privacy and independence from cloud providers.
  • Cheaper and much faster than cloud providers.
  • They can be very quiet (with liquid-liquid CDU).
  • Flexibility and the possibility of offline use.
  • Gigantic amounts of coherent memory.
  • They are very power-efficient.
  • The lowest possible latency.
  • Reliable liquid cooling.
  • They are beautiful.
  • CUDA enabled.
  • Run Linux.
  • GB200 Blackwell

    The coming Nvidia GB200 Grace-Blackwell Superchip has truly amazing specs to show off. ready-to-use rack server systems with multiple NV-linked Nvidia GB200 Grace-Blackwell (up to 72) will arrive at the end of Q4 2024.

    What is the difference to alternative systems?
    The main difference between GH200/GB200 and alternative systems is that with GH200/GB200, the GPU is connected to the CPU via a 900 GB/s NVLink vs. 128 GB/s PCIe gen5 used by traditional systems. Furthermore, multiple superchips can be connected via 900/1800 GB/s NVLink vs. orders of magnitude slower network connections used by traditional systems. Since these are the main bottlenecks, GH200/GB200's high-speed connections directly translate to much higher performance compared to traditional architectures. Also, multiple NV-linked GH200 or GB200 act as a single giant GPU (CPU-GPU superchip) with one single giant coherent memory pool.

    We partner with Phoronix to benchmark as much as possible and will hopefully soon have solid data in the form of publicly available benchmarks to see how the different solutions compare for different workloads. The comparisons are expected to vary greatly for different workloads. If you want to know how your workloads performs on GH200/GB200 or Mi300 you can apply for a remote bare metal test here: Try

    What is the difference to server systems of competitors?
  • Size: We focus on systems that are not bigger than one singe rack. With GB200 that gives you more than an exaflop of compute. If that is, for some reason, really not enough for you, we are happy to make you a custom offer. But for many people, one complete rack is more than needed and too expensive. That is why we also offer smaller systems with only 4, 8, 16 or 18 superchips. We are to our knowledge the only ones where you can get systems smaller than a complete GH200 NVL32 or GB200 NVL72 rack.
  • In-rack CDU: Our rack servers systems come stand with liquid cooling and a CDU integrated directly into the rack. You can choose between an air-liquid and liquid-liquid CDU.
  • Ready-to-use: In contrast to other vendors, our systems come fully integrated and ready-to-use. Everything that is needed is included and tested. All you need to do is plug your system in to run it.
