If you’re interested in building your very own 256-Core RISC-V supercomputer, you might find this project video intriguing. It details the ambitious method of creating a 256-core RISC-V supercomputer using interconnected microcontrollers. The video takes you through the intricacies of design, assembly, and troubleshooting, highlighting the challenges encountered and the ingenious solutions devised along the way.
The journey begins with a modest yet crucial step: assembling 16 RISC-V microcontrollers, each connected by an 8-bit bus. The inclusion of a pink LED on each microcontroller serves a dual purpose:
- Simplifying the implementation of the bus system
- Facilitating the monitoring of the system’s functionality
This initial setup forms the bedrock of your super cluster, setting the stage for the complex work ahead.
Building a DIY 256-Core RISC-V Supercomputer
With the foundation laid, it’s time to scale up to a larger cluster comprising 16 super clusters. This phase presents significant design challenges, particularly in managing GPIO expansions and bus systems. The key to success lies in ensuring effective communication between microcontrollers without overcrowding the bus. Striking the right balance is crucial to maintaining optimal performance and reliability.
To effectively manage the super clusters, a cluster blade is introduced. This intermediate board, equipped with two microcontrollers, acts as a supervisor for the super clusters. By assigning each super cluster its own bus, data congestion is prevented, ensuring smooth and efficient communication. The cluster blade proves to be a game-changer in the overall design, streamlining data flow and enhancing system performance.
At the core of the mega cluster lies the blade base, responsible for connecting the cluster blades and interfacing with USB. To ensure optimal performance, faster clock speeds are essential at this level. Larger microcontrollers must efficiently handle data from their smaller counterparts, necessitating quick and reliable data processing. The blade base serves as the central hub, ensuring seamless integration and communication throughout the system.
The assembly process demands meticulous attention to detail, as each connection and component plays a vital role in the overall functionality of the supercomputer. Initial testing yields promising results, with synchronized LED blinking indicating correct communication between microcontrollers. However, a missing command line in the bus system is discovered, requiring further investigation and modification.

To address the missing command line issue, a clever solution is devised. By repurposing the clock line to serve as a command signal, better control and communication between microcontrollers are achieved. Additionally, a collision detection protocol is implemented to handle data packet collisions effectively. This modification showcases the importance of adaptability and problem-solving in the face of unexpected challenges.
Ensuring Smooth Operation: Handling Collisions
Collisions are an inevitable part of any complex system, and this unique project is no exception. To mitigate the impact of collisions, processors are programmed to detect them and resend packets after randomized waiting times. Each processor is assigned a unique ID, ensuring fair distribution and collision detection. This approach minimizes data loss and guarantees smooth operation, even in the face of occasional collisions.
Through rigorous live testing, the bus system and protocol are put to the test. The system successfully handles collisions and delays, proving the effectiveness of the unique project design choices and modifications. The impressive project and the countless hours of hard work and problem-solving that went into creating this DIY 256-core RISC-V supercomputer are truly staggering.
As you can see from the video, building a 256-core RISC-V supercomputer is not for the fainthearted but offers a journey filled with challenges, innovations, and triumphs. By carefully navigating the complexities of design, assembly, and troubleshooting, it is possible to create a 256-Core RISC-V supercomputer.
