AI engines: GPUs and beyond

© Mark Ollig

Founded on April 5, 1993, NVIDIA Corp. is headquartered in Santa Clara, CA.

“NVIDIA” originates from the Latin word “invidia,” meaning “envy.” The company’s founders reportedly chose this name with the aim of creating products that would be the envy of the tech industry.

Initially, NVIDIA focused on developing graphics processing units (GPUs) for the computer gaming market.

Supercomputing graphics cards rely on specialized electronic circuits, primarily the GPU, to perform a large number of calculations.

These circuits act as the “computing muscle,” allowing the card to handle complex graphics rendering, AI processing, and other workloads.

GPUs execute various computing programs, specifically complex calculations, and accelerate the processing of applications with high graphical processing needs and videos.

Graphics cards are used for computer gaming, self-driving cars, medical imaging analysis, and artificial intelligence (AI) natural language processing.

The growing demand for large language AI models and applications has expanded NVIDIA’s graphics card sales.

The NVIDIA H200 Tensor Core GPU datasheet states it is designed for generative AI and high-performance computing (HPC). It is equipped with specialized processing units designed to enhance performance in AI computations and matrix operations.

It is a powerful graphics card designed to enhance AI and high-performance computing (HPC) tasks.

The NVIDIA H200 Tensor Core GPU features 141 GB of High-Bandwidth Memory 3 Enhanced (HBM3e), ultra-fast memory technology enabling rapid data transfer of large AI language models and scientific computing tasks.

The H200 is the first graphics card to offer HBM3e memory, providing 1.4 times more memory bandwidth compared to the H100 and nearly double the data storage capacity.

It also has a memory bandwidth of 4.8 terabytes per second (TB/s), which can transport large amounts of data over a network.

This memory bandwidth significantly increases the computing capacity and performance, improving scientific computing to allow researchers to work more efficiently.

It is based on NVIDIA’s Hopper architecture, which enhances GPU performance and efficiency for AI and high-performance computing workloads. It is named after computer scientist Grace Hopper.

AI uses “inference” to understand new information and make decisions. To do this quickly, AI can use multiple computers in the “cloud” (computers connected over the internet).

The H200 boosts inference speed to twice the levels as compared to H100 graphics cards for large language models like Meta AI’s Llama 3.

The higher memory bandwidth ensures faster data transfer, reducing bottlenecks in complex processing tasks.

It is designed to process the increasingly large and complex data processing needs of modern AI technology.

As these tasks become more complex, GPUs need to become more powerful and efficient. Researchers are exploring several technologies to achieve this.

Next-generation memory systems, like 3D-stacked memory, which layers multiple memory cells, will enhance computing data transfer speeds.

High-Performance Computing (HPC) leverages powerful computers to solve complex challenges in fields like scientific research, weather forecasting, and cryptography.

Generative AI is a technology for creating writing, pictures, or music. It also enhances large language models, those capable of understanding and creating text content resembling human origination.

Powerful GPUs generate significant heat and require advanced cooling.

AI optimizes GPU performance by adjusting settings, improving efficiency, and extending their lifespan. Many programs use AI to fine-tune graphics cards for optimal performance and energy savings.

Quantum processing uses the principles of quantum mechanics to solve complex problems that are too difficult to address using traditional computing methods.

Neuromorphic computing, represented by its spiking neural networks, seeks to duplicate the efficiency and learning architectures inspired by the human brain.

As GPUs push the limits of classical computing, quantum computing is emerging with QPUs (quantum processing units) at its core.

QPUs use quantum mechanics to solve problems beyond the reach of even the most powerful GPUs, with the potential for breakthroughs in AI and scientific research.

Google Quantum AI Lab has developed two quantum processing units: Bristlecone, with 72 qubits, and Sycamore, with 53 qubits.

While using different technologies, QPUs and GPUs may someday collaborate in future hybrid computing systems, leveraging their strengths to drive a paradigm shift in computing.

Google’s Tensor Processing Units (TPUs) specialize in deep learning tasks, such as matrix multiplications.

Other key processors fueling AI computing include Neural Processing Units (NPUs), which accelerate neural network training and execution, and Field-Programmable Gate Arrays (FPGAs), which excel at parallel processing and are essential for customizing AI workloads.

Additional components utilized for AI processing are Application-Specific Integrated Circuits (ASICs) for tailored applications, System-on-Chip designs integrating multiple components, graphics cards leveraging GPU architecture, and Digital Signal Processors (DSPs).

These components are advancing machine learning, deep learning (a technique using layered algorithms to learn from massive amounts of data), natural language processing, and computer vision.

GPUs, TPUs, NPUs, and FPGAs are the “engines” fueling the computational and processing power of supercomputing and artificial intelligence.

They will likely be integrated with and work alongside quantum processors in future hybrid AI systems.

I still find the advancements in software and hardware technology that have unfolded throughout my lifetime incredible.
I used Meta AI's large language model program
(powered by Llama 3) and its text-to-image generator
 (AI Imagined) to create the attached image of two
 people standing in front of a futuristic "AI Quantum Supercomputer."
The image was created using my text input, and the AI created the
image with no human modifications.
