YATRMC

YATRMC, short for Yet Another Time and Resource Management Controller, is a fictional open-source software framework used in introductory texts and tutorials to illustrate scheduling and resource management in distributed systems. It is not a real project, but it serves as a neutral reference model for concepts and workflows.

Overview: YATRMC is designed to demonstrate how a controller can coordinate task execution and resource allocation across a cluster. It emphasizes modularity, with separate components for planning, execution, and monitoring, and it uses pluggable policies to illustrate how different strategies affect performance and fairness.

Architecture: The reference architecture includes a core scheduling engine, a resource manager, and a policy plugin interface. A data plane collects metrics; a control plane communicates with worker nodes and storage backends. The project models both CPU and accelerator resources and supports REST and gRPC interfaces for integration.

Development and usage: In educational scenarios, developers implement adapters for common resource types, configure backfilling and deadline-based scheduling, and run simulated workloads to observe behavior under failure and scaling conditions. Tutorials typically demonstrate trace-based debugging and policy evaluation.

Impact and relation: As a fictional example, YATRMC is used to explain core concepts in resource management, scheduling, and multi-tenant isolation, without endorsing any real system. It helps students and practitioners compare different approaches in a neutral setting.
