Real-Time Scheduling & Multicore Computing Architecture Training by Tonex
Multicore computing offers increased processing capacity while introducing interference, synchronization, and schedulability challenges for deterministic submarine applications. This course examines real-time scheduling principles for multiple processor cores, with attention to task allocation, worst-case execution assumptions, shared cache and memory effects, interrupt routing, and concurrent execution. Participants evaluate when theoretical scheduling models align with observed platform behavior and how engineering teams should manage uncertainty. The course ties resource budgeting, verification, and change control to modular computing architectures used in constrained naval environments.
Shared computing resources can also expose sensitive workloads to unauthorized observation or interference. Robust scheduling architecture supports cybersecurity through protected resource allocation, controlled privileged access, and evidence-based isolation of critical functions.
The practical training approach includes exercises, real-world case studies, and examples of processes and documentation used in submarine software engineering projects, including multicore task allocation maps, interference budgets, scheduling analyses, and processor timing assessment records.
