What is Colossus AI?

Colossus AI is a top-notch supercomputer known for its AI workloads. It has 100,000 NVIDIA Hopper GPUs, more than Frontier, the US’s top supercomputer. This makes Colossus one of the most powerful machines today⁶.

It was set up in just 122 days and started training in 19 days⁶.

Defining Colossus AI

Colossus AI is a big step up in supercomputer tech. It boosts the power needed for new AI ideas. It uses NVIDIA tech for top performance, reaching 98.9 exaFLOPS for dense tasks⁶.

It can go up to 395 exaFLOPS with sparse data. It also has a smart design to handle heat well, key for AI tasks.

Key Components and Features of Colossus

The Colossus supercluster has 100,000 GPU servers. Each server has eight NVIDIA HGX H100 GPUs, showing its huge size⁷. It has 1,500 GPU racks in 200 arrays for better layout⁷.

Each HGX H100 server has a fast 3.6 Terabits per second network speed. This is thanks to 400GbE dedicated NICs for each graphics card, making data flow smooth and fast⁷.

Colossus uses NVIDIA’s Spectrum-X Ethernet fabric. This is different from most AI clusters, which use InfiniBand. It manages congestion well and delivers packets fast without delay⁶.

The 51.2 Tbps Spectrum SN5600 switch, with 64 800GbE ports, boosts its networking skills⁶.

Technical Specifications of Colossus AI

The Colossus AI supercomputer has an amazing hardware design. It uses the latest components to boost its performance. Built in just 122 days, it has 100,000 NVIDIA H100 GPUs. These units are put together in a complex way⁸⁹.

Hardware Overview

Colossus uses Supermicro liquid-cooled racks. Each rack has eight servers with 64 NVIDIA H100 GPUs. This setup helps manage heat well and keeps the system running smoothly⁸. It’s also planning to add more GPUs, showing its commitment to AI power¹⁰.

Networking Capabilities

The network of Colossus is built with the NVIDIA Spectrum-X Ethernet platform. It allows for fast data transfer at up to 800Gb/s. This network is much better than older systems, reaching 95% data throughput¹⁰.

Performance Metrics

Colossus is made for top-notch performance evaluation in AI training. It works much faster and more efficiently than old systems. It even started training in just 19 days after setting up, showing its quick start-up¹⁰⁹.

The Role of NVIDIA in Colossus AI Development

NVIDIA has played a key role in making Colossus AI. It uses advanced hardware to improve AI performance. The heart of this effort is NVIDIA’s Hopper GPUs, with 100,000 units now and set to double to 200,000. This makes Colossus the world’s largest AI supercomputer¹¹¹².

These GPUs are made for tough AI tasks. They help the supercomputer handle huge data sets efficiently.

NVIDIA’s Hopper GPUs

The Hopper architecture is key to Colossus’s high performance and fast training times. Building and starting Colossus took just 122 days. This is much faster than the months or years needed for traditional supercomputers¹¹¹².

This quick start shows how these GPUs speed up AI development in many fields.

Spectrum-X Networking Platform

The Spectrum-X platform works with Hopper GPUs to improve data flow. It uses the Spectrum SN5600 Ethernet switch, which can handle speeds of up to 800 Gb/s. This ensures Colossus keeps a high 95% data throughput with little latency and packet loss¹¹¹².

Traditional Ethernet can’t handle Colossus’s scale, leading to congestion and lower efficiency. The combination of Hopper GPUs and Spectrum-X makes Colossus a leader in AI research, training AI models at record speeds.
