Supercomputing Paradigm Shift: Tesla's Dojo?

Tesla's Dojo supercomputer has triggered a shift in the realm of supercomputing, garnering significant attention following a positive appraisal from Morgan Stanley despite the customary controversy associated with Elon Musk. In contrast to tech giants like NVIDIA, Intel, HPE, Lenovo, IBM, and Dell, which have traditionally dominated AI and supercomputer hardware, Tesla's foray into chip design, supercomputing, and AI signifies more than mere diversification. It underscores Tesla's and, more significantly, Elon Musk's approach to innovation and vertical integration.

As of July, Tesla has achieved the sale of 4,527,916 vehicles throughout its history, each of which contributes valuable data to aid in the development of fully self-driving cars. This amalgamation of a vast network of mobile sensors, cameras, robust edge computing, and an in-house-built supercomputer for data analysis represents an innovative departure from the conventional role of an automaker. Tesla is transcending its identity as a mere car company.

To grasp the essence of Dojo, it's imperative to scrutinize the prevailing landscape of AI computers and supercomputing. Traditional supercomputers like NVIDIA's A100 GPUs, IBM's Summit, and HPE's Cray Exascale serve diverse purposes, catering to scientific research, complex simulations, and extensive data analytics. However, these systems are designed to handle a broad spectrum of tasks, unlike Tesla's Dojo, which is meticulously tailored for real-world data-driven AI computer vision.

Tesla's Dojo aspires to revolutionize AI processing by channelling all its resources into enhancing Full Self-Driving (FSD) technology. Through this vertical integration strategy, Tesla seeks to construct an ecosystem encompassing hardware, data, and real-world applications. This could herald a new era of supercomputing, uniquely engineered to grapple with real-world data challenges.

In the past, Tesla relied on NVIDIA's GPU units for training neural networks in its autopilot systems. While specific details about performance metrics remained elusive, Tesla claimed to operate the "fifth-largest supercomputer in the world" as of 2021, with reports suggesting an inventory of over 10,000 NVIDIA A100 GPUs. This positioned Tesla among the world's largest training system operators, a practice it maintained for at least two years.

Dojo's cornerstone, the D1 chip, produced by TSMC using 7 nm semiconductor nodes, boasts a substantial die size of 645 mm2 and a staggering 50 billion transistors. Employing a RISC-V architecture and custom instructions, Dojo's unique architecture sets it apart. The system's scalability is achieved through the addition of ExaPODs, each capable of housing up to 1,062,000 cores and delivering 20 exaflops of computing power. This scalability becomes crucial when considering the colossal data generated by Tesla's vehicle fleet. Additionally, Dojo incorporates PyTorch and introduces two novel floating-point formats, CFloat8 and CFloat16, optimizing vector processing and storage efficiency.

While some industry experts view Dojo as an incremental rather than a transformative innovation, and others dismiss Musk's proclamations as mere rhetoric, it's imperative to contextualize Dojo within Tesla's broader FSD objectives and the future of AI applications. Dojo's in-house development confers a level of control that expedites development cycles, fostering innovation in autonomous vehicles and potentially extending to other AI domains, such as computer vision-powered robotics, within Tesla's purview.

Tesla's distinctive approach foreshadows a potential paradigm shift in the broader AI landscape. Departing from the conventional approach of building models based on private data, the emerging standard revolves around tailor-made integration solutions designed for specific purposes. While it is premature to make definitive assertions, Tesla's strategy is likely to remain exclusive, accessible primarily to a select group of affluent individuals.

In summary, the advent of Dojo heralds a transformation in supercomputing, marked by an emphasis on edge-driven, vertically integrated, specialized, and scalable design. While time will determine the extent of its impact on supercomputing, one thing is certain: Dojo affords Tesla a technical edge that traditional automakers are unlikely to replicate. By focusing on real-world applications and showcasing its fundamentally distinct architecture, Tesla's Dojo emerges not only as a tool for FSD but also as a significant stride forward in AI and supercomputing, which are increasingly converging.
