I built a 17-agent AI swarm on my phone — here's how

说明与用途

在Pixel 6手机上运行的17个AI代理群，完全离线，利用线程、NumPy和代码优化实现近实时报告。

问题

Running a distributed, multi‑agent AI system entirely on a mobile device without cloud offloading.

结果

The swarm runs smoothly on a Pixel 6, with agents reporting in near real‑time and a responsive UI, proving complex on‑device AI is achievable with careful optimization.

工作流

• Define Agent base class and Coordinator class
• Implement 17 agent subclasses (e.g., SpikeDetectorAgent, TrendDetectorAgent)
• Simulate sensor data stream
• Use threading instead of multiprocessing to run agents
• Replace Python lists with NumPy arrays for speed
• Profile with cProfile and optimize string formatting
• Simplify agent algorithms to reduce computation
• Tune BeeWare build with compiler flags
• Collect reports in Coordinator and generate summary
• Display summary via BeeWare Toga UI

证据

I initially tried using multiprocessing to run each agent in a separate process. While theoretically good for CPU‑bound tasks, the overhead of inter‑process communication was massive on the phone.

Threading instead of multiprocessing drastically improved performance.

NumPy arrays became my best friend. While Python lists are convenient, NumPy arrays are significantly faster for numerical operations.
