SchedulingParameters

SchedulingParameters is a data structure used by a scheduler to control how tasks are executed. It encapsulates constraints and preferences that influence when, in what order, and for how long a task runs.

Typical fields include priority, deadline, timeSlice, preemptionPolicy, maxConcurrent, cpuQuota, memoryQuota, affinity, agingPolicy, and cancellationPolicy.

Usage involves attaching SchedulingParameters to a task at submission. The scheduler reads these values during decision making to determine execution order, preemption decisions, and resource allocation. If no parameters are provided, the system defaults govern behavior.

Contexts include operating systems, where parameters may map to priority or real-time classes, as well as distributed job schedulers and cloud resource managers, where they can govern concurrency, backoff, and retry policies.

Implementation notes: SchedulingParameters are usually represented as a small object with a defined interface (for example, a class, struct, or dictionary). They may be immutable or mutable depending on the system. Access should be thread-safe in concurrent environments. Some fields may be advisory rather than binding, and implementations may ignore or override conflicting values.
