The Power of Champollion: Exploring HPE's AI Supercomputer in Grenoble

In the stunning city of Grenoble, France lies one of the most legendary HPE sites in the world. Last summer, I had the incredible opportunity to visit and spend a couple of days with HPE's iconic AI supercomputer, Champollion. As an enthusiast of enterprise technologies, I was eager to Delve into the world of supercomputing and understand what sets Champollion apart from regular computers. In this article, I will take You on a Journey to discover the true power and capabilities of this remarkable machine.

The History of Grenoble and HPE

Grenoble, surrounded by the majestic Alps and brimming with friendly people, is renowned for its high concentration of research, technology, and innovation companies. It is also home to one of the most historic HPE offices in the world. Celebrating its 50th anniversary last year, the site in Grenoble has a colorful history, starting with the research and development of HP servers. Over the years, Grenoble has become a center for High-Performance Computing (HPC), serving as the EMEA center for benchmarking, research, and test environments. Notably, it has fostered collaborations with industry leaders like NVIDIA, resulting in the establishment of the HPE-NVIDIA Center of Excellence 15 years ago.

The Need for AI Supercomputers

Supercomputers play a critical role in tackling the most computationally intensive tasks, such as weather forecasting and Scenario modeling. However, the decision to build an AI supercomputer in Grenoble Stems from the need to enable customers and partners to test AI workloads at Scale. While running experiments on a single GPU may seem straightforward for data scientists, achieving scalability presents a different challenge. The synchronization of data, computing power, and communication becomes essential to deliver the full performance of a system. Thus, Champollion aims to provide a platform for customers to assess the performance of AI configurations on a larger scale, addressing a significant hurdle faced by many.

What is Champollion?

Champollion is more than just a supercomputer; it is a powerful AI machine designed to push the boundaries of deep learning and machine learning. The system remains within HPE, serving as a benchmark center for evaluating the performance of supercomputers that will be sold to customers worldwide. While the champagne system in Grenoble is a subset of the technology available to customers, it serves as a testing ground for ensuring seamless AI configurations. The focus of Champollion revolves around training at scale, empowering customers to overcome the challenges posed by large-Scale AI workloads.

The Components of Champollion

Under the hood of Champollion lies a remarkable network of components. The supercomputer comprises 20 HPE Apollo 6500 Gen10 Plus servers, each equipped with eight NVIDIA A100 Tensor Core GPUs. In total, Champollion boasts an astounding 160 high-performance graphics adapters, making it a force to be reckoned with in the world of computing. These Apollo servers are interconnected through NVIDIA Quantum InfiniBand switches, forming the backbone of this mighty machine. The GPUs are connected using a dedicated high-bandwidth bus called Envelink, ensuring efficient communication between nodes and paving the way for optimal performance.

The Difference between a Supercomputer and Regular Computer

One may question the distinction between a supercomputer and a regular computer, Wondering if merely connecting multiple computers together could achieve the same result. However, the key differentiator lies in scalability and efficiency. Mere stacking of servers yields nothing more than a stack of individual machines that Consume substantial energy. The central goal of High-Performance Computing (HPC) is to achieve scalable performance. When running HPC applications on a system, the aim is to harness 100% of the system's performance. Every doubling of servers should lead to a proportional doubling of performance. Supercomputers, therefore, focus on efficient utilization of nodes and linear performance scalability, leaving no room for overhead.

The Purpose of Champollion

Champollion's primary purpose revolves around enabling the efficient training of AI models. Deep learning and machine learning algorithms require substantial computational resources, and Champollion aims to provide the platform for training at scale. By harnessing the power of 160 GPUs, this supercomputer tackles the most complex AI workloads, ensuring optimal performance and speed. The reality of AI implementation often requires fine-tuning and practical tips and tricks that may differ from marketing claims. Champollion serves as a testing ground within HPE, allowing for refinement and optimization before deploying AI solutions to customers worldwide.

The Challenges of Scalability

Scalability poses a significant challenge in the world of supercomputing. While running experiments on a single GPU may yield desirable results, expanding to hundreds or thousands of GPUs requires meticulous synchronization and optimization. The communication between nodes, efficient distribution of data, and coordination of computations become crucial factors for achieving scalability. Champollion presents an environment for researchers and data scientists to explore and overcome the challenges associated with training AI models at scale. This testing ground within HPE ensures that customers receive top-of-the-line AI configurations that deliver exceptional performance.

The Efficiency of Supercomputers

Supercomputers like Champollion are renowned for their efficiency in utilizing every last bit of computational power. Unlike traditional computers, where individual machines operate independently, supercomputers function as a seamless, enormous computing unit. The performance of each node is harnessed to its full potential, leaving no computing power underutilized. This level of efficiency enables supercomputers to tackle the most complex tasks, making them indispensable for domains such as weather forecasting, scientific research, and cutting-edge AI development.

Under the Hood of Champollion

Within the supercomputer Champollion lies an impressive infrastructure comprising 20 HPE Apollo 6500 Gen10 Plus servers, each packed with eight NVIDIA A100 Tensor Core GPUs. These servers are interlinked using NVIDIA Quantum InfiniBand switches, establishing high-speed communication channels. The GPUs themselves are connected through the Envelink bus, enabling seamless cooperation and data sharing between nodes. Champollion's stature as one of the world's fastest computers is reflected in its notable ranking within the Top500, currently standing at 372. With hardware upgrades on the horizon, Champollion is set to climb even higher in the rankings, cementing its status as a powerhouse in the world of supercomputing.

The Ranking of Champollion

Champollion's impressive capabilities and performance are not just empty claims. Its position in the Top500 list, a prestigious ranking of the world's most powerful computers, solidifies its standing. As the 372nd most powerful machine, Champollion exemplifies the exceptional computational power harnessed within its infrastructure. This ranking further strengthens its significance within HPE and the broader supercomputing community, serving as a testament to its extraordinary capabilities.

The Future of Champollion and Green Lake
