The GPU Bottleneck Problem

A critical challenge in AI development is the GPU bottleneck. With AI business projected to exceed $400 billion by 2027 and growing at an annual rate of nearly 40%, the demand for GPU resources has skyrocketed. Global chip shortages and complex GPU manufacturing processes have created significant constraints, limiting researchers' and businesses' ability to scale and innovate in AI.

This bottleneck presents a particular hardship for small and medium AI companies that struggle to secure affordable GPU resources. Decentralized GPU networks offer a viable alternative by providing access to a marketplace of distributed GPUs, enabling more efficient sourcing from diverse providers.

Key Challenges:

  • Global chip shortages
  • Complex manufacturing processes
  • High acquisition costs
  • Centralized resource control
  • Accessibility constraints

How Decentralized GPU/CPU Networks Function

Decentralized GPU farms operate as networks of geographically distributed computers equipped with graphics processing units that collaborate to perform intensive computational tasks. These networks leverage blockchain technology to coordinate and optimize GPU resource usage across various locations and participants.

Network Participants and Roles

Contributors

Individuals or entities providing GPU/CPU power to the network, incentivized through rewards typically paid in cryptocurrency tokens.

Clients

Entities requiring computational resources for tasks such as AI model training, rendering, or scientific simulations.

Task Allocation and Processing Flow

1

Job Submission & Subdivision: The job is submitted by a client and subdivided into smaller tasks by smart contracts.

2

Task Distribution: Tasks are distributed throughout the network based on each contributor's GPU capability and availability.

3

Processing: Contributors process their allocated work using their GPUs.

4

Result Aggregation: Results are returned to the blockchain for verification and aggregation.

5

Reward Distribution: Upon successful completion and verification, contributors receive automatic reward distribution managed by smart contracts.
