Smolcluster runs distributed Llama 3.2 on Mac Mini M4

Yuvraj Singh’s Smolcluster enables distributed Llama 3.2-1B-Instruct inference across a cluster of three Mac Mini M4s using a custom AllToAll architecture. Built from scratch with only Python’s standard socket library, the project provides an educational, low-level implementation of distributed deep learning that bypasses complex enterprise frameworks.

// ANALYSIS

Smolcluster proves that high-performance distributed inference is achievable on consumer hardware using only fundamental networking primitives and low-latency interconnects.

–AllToAll architecture removes master-worker bottlenecks by allowing any node in the cluster to serve requests and share activations.
–Socket-only communication demonstrates that Thunderbolt 4 bandwidth is sufficient for efficient coordination on Apple Silicon clusters.
–Activation averaging during decoding offers a robust Data Parallelism mechanism tailored for memory-constrained "smol" hardware.
–The project’s educational focus makes the mechanics of FSDP and EDP accessible through minimal, one-page Python scripts.
