) * feat(service): support multi-node inference in gateway controller Enable inference instances to span multiple physical nodes for large models (e.g. Llama-3.1 405B with tp_size=16 across 2x 8-GPU nodes). When nnodes > 1, the controller groups every nnodes workers into one inference instance, allocates rendezvous ports for distributed init, forks inference servers on all nodes per group, and only records the head node as the HTTP endpoint. When nnodes=1 (default), behavior is identical to the existing code. Key changes: - Add nnodes field to GatewayControllerConfig (default 1) - Extend vLLMConfig.build_args()/build_cmd() with n_nodes/node_rank - Restructure controller fork loop with grouped multi-node support - Register forked inference processes in _forked_services for cleanup - Fix server_infos indexing to avoid IndexError when nnodes > 1 - Data proxies only fork on head nodes (one per DP group) - Defensive checks: worker count validation, RuntimeError over assert Refs: #1149 * refactor(inference): replace nnodes with n_gpus_per_node for multi-node configuration
…SDK example (#1177) Add AgentServiceController and Guard for production-style orchestration, replace tau2/PydanticAI demo with Claude Agent SDK integration. Key changes: - Add controller/ with scheduler-based Guard creation (mirrors GatewayInferenceController) - Add guard/ module (pass-through to areal.infra.rpc.guard) - Add config dataclasses with __post_init__ validation - Replace Tau2Agent with ClaudeAgent (session-persistent ClaudeSDKClient) - Session lifecycle: close_session, Worker endpoint, DataProxy propagation - Initialize rollback on failure, register-before-commit in scale_up - Unregister with retry in scale_down, skip pair on failure - Lock-protected _pairs, ThreadPoolExecutor health monitor - Timing-safe WebSocket auth via hmac.compare_digest BREAKING CHANGE: areal.experimental.agent_service.__init__.py no longer re-exports symbols. Import from submodules directly.
