About us
The Connecticut Java Users Group organizes monthly meetings on new and emerging Java technologies. It aims to help professionals stay abreat of the latest developments in Java and related open source projects. Meetings are free and open to the public. The group was initially founded in 2000 as a special interest group of the Connecticut Object Oriented Users Group. It is presently chaired by Ryan Cuprak who assumed leadering of the JUG in December of 2002.

GPU Homelab: Agentic Orchestration with Quarkus, LangChain4j, and Kubernetes
Trinity College, 300 Summit Street, Hartford, CT, USWhat happens when you wire three rigs loaded with NVIDIA GPUs into a Kubernetes cluster — then unleash a multi-agent AI system on top of it?
In this session, Jonathan dissects a GPU homelab built for hands-on agentic AI: bare-metal infrastructure running local LLMs, orchestrated entirely with open-source tooling. You'll see Proxmox virtualization with GPU passthrough, Talos Linux, GitOps with Flux, and an emerging open-source Kubernetes operator — currently in active development — that schedules agents across GPUs, wires up RAG pipelines and MCP tool servers, and drives multi-agent consensus discussions.
The agent runtime is built with Quarkus and LangChain4j — compiled to GraalVM native images with a minimal memory footprint and sub-second startup per agent. We'll dig into LangChain4j's tool-calling API, how it drives real agentic behavior, SmallRye config patterns for dynamic agent wiring, and what production-grade deployment actually looks like on Kubernetes.
No cloud required. No vendor lock-in. Every layer is open source.Whether you're drawn to local LLMs, Kubernetes operators, or LangChain4j for agentic workflows, you'll leave with concrete patterns you can take home and run.
