Eclipse Timpani

Eclipse Timpani provides a real-time scheduling submodule for the Eclipse Pullpiri workload orchestrator, providing a framework that guarantees deterministic execution of safety-critical workloads.

In-Scope:

• Time-Triggered Scheduling: Periodic task execution based on static schedule tables (Signal-driven dispatch)
• Distributed Architecture: Timpani-O (orchestration bridge) and Timpani-N (node executor) components
• eBPF-based Monitoring: Non-intrusive scheduler observability (wakeup latency, execution time tracking)
• Deadline Miss Detection and Reporting: Detection and notification of real-time task deadline violations
• Pullpiri Integration: Integration with Pullpiri orchestrator via gRPC-based communication
• RT Linux Support: Real-time scheduling on PREEMPT_RT patched kernel environments
• Declarative Configuration: YAML-based task and schedule table configuration

Out-of-Scope:

• General-purpose RTOS development (focus on Linux kernel-based solutions)
• High-level workload orchestration (Pullpiri domain)
• Hardware-specific driver development
• Functional Safety Certification itself
