scheduler
A scheduler is a component responsible for managing and coordinating the execution of tasks or jobs across available resources.
The scheduler determines when and where to execute tasks based on resource availability, job priorities, and scheduling policies to optimize utilization and minimize latency.
Key functions include resource tracking, task prioritization, and fault tolerance through job rescheduling and retries to maintain system performance.
Used in batch processing, interactive systems, and distributed environments, schedulers implement policies like FCFS, Round Robin, and advanced algorithms to balance workloads across heterogeneous resources.
