## Momagrid: Guide to the Architecture and Practice of a Decentralized LLM Inference Network

# Momagrid: Guide to the Architecture and Practice of a Decentralized LLM Inference Network
Momagrid is a decentralized LLM inference network implemented in Go, supporting multi-node distributed collaboration and task orchestration via Structured Prompt Language (SPL). This article analyzes its architectural design, node classification mechanism, load balancing strategy, and integration plan with the SPL ecosystem.
Core values: Integrate scattered computing resources, simplify distributed inference, suitable for scenarios such as elastic scaling for small and medium-sized enterprises, resource integration for research institutions, and developers building private model service meshes.

## Background and Motivation

## Background and Motivation
With the explosive demand for LLM applications, a single GPU can hardly meet high-concurrency inference, while scattered computing resources have not been effectively integrated. Momagrid emerged to build a decentralized inference network, pooling GPU resources from multiple machines into a unified inference cluster.
Applicable scenarios: Elastic scaling of inference capabilities for small and medium-sized enterprises, integration of multi-node resources in research labs, and developers building local private model service meshes. Through standardized protocols and automated scheduling, complex distributed inference is simplified to a single command.

## Technical Architecture and Resource Scheduling

## Technical Architecture Overview
Momagrid adopts a Hub-Agent architecture: Hub is responsible for task distribution and state management, while Agent is deployed on GPU nodes to execute inference. Implemented in Go, leveraging concurrency and network advantages, a single `mg` binary integrates Hub services and client commands. Supports SQLite (for rapid prototyping) and PostgreSQL (for production environments) databases. Network communication uses a hybrid HTTP REST API + SSE mode to solve NAT intranet penetration issues.

## Node Classification and Resource Scheduling
Node classification system: Divided into Platinum (≥16GB GPU memory / ≥60 tokens/s), Gold (≥10GB / ≥30), Silver (≥6GB / ≥15), and Bronze levels based on GPU memory and TPS. Scheduling strategy: Online status first → level next → lightest load first, combined with randomization to avoid concentration, achieving load balancing.

## Node Management and SPL Ecosystem Integration

## Node Management and Health Monitoring
Agent heartbeat mechanism: Sends a heartbeat to Hub every 90 seconds, reporting status, model list, and performance; Hub marks timed-out nodes as offline. Node registration: `mg join` automatically discovers Hub, detects Ollama models, and registers; administrators can view node status via `mg agents`. Supports management mode: Start Hub with `--admin`, new nodes wait for approval, requiring `mg hub approve` authorization.

## SPL Ecosystem Integration and Parallel Execution
Deep integration with SPL (Structured Prompt Language): SPL defines multi-step AI workflows, and Momagrid serves as a backend adapter to support distributed execution. Integration method: Set `MOMAGRID_HUB_URL`, run SPL scripts with `--adapter momagrid`. Parallel execution: `run_all.py` submits multiple SPL tasks, Hub distributes them to multiple nodes for parallel processing; `--workers` limits concurrency.

## Deployment, Operation & Maintenance, and Application Scenarios

## Deployment and O&M Practices
Simple deployment: For single-machine testing, use `mg hub up --port 9000` (automatically initializes SQLite); switch to PostgreSQL for production: `mg hub up --db "postgres://user:pass@localhost/momagrid?sslmode=disable" --port 9000`. Data migration: `mg hub migrate` supports lossless migration from SQLite to PostgreSQL. Cluster expansion: Add nodes with `mg join`; use Pull mode for cross-network segments; `mg peer` supports multi-Hub federation.

## Application Scenarios and Value
Value: Transforms scattered computing power into a unified inference service layer. Typical scenario: Two-machine local area network (a high-end GPU machine acts as Hub + Agent, another as Agent). Developer-friendly: Seamlessly connects to the Ollama ecosystem (supports Qwen, Llama, etc.), `mg submit` sends requests without caring about nodes. Test suite: `mg test` runs prompts in batches, collects performance data, and exports JSON.

## Summary and Outlook

## Summary and Outlook
Momagrid is a pragmatic decentralized AI infrastructure, focusing on solving distributed inference problems (node discovery, scheduling, load balancing, failover) without complex blockchain or token mechanisms, making it simple and easy to implement.
Future directions: Support more inference backends (vLLM, TGI), fine-grained resource quota management, and preemptive scheduling based on task priority. Suitable for teams researching the construction of elastic LLM services in private environments.
