Struct JobResources

Struct Documentation

struct JobResources

Complete resource allocation information from job scheduler.

This structure contains all resource allocation information extracted from the job scheduler environment. It provides a unified interface for resource information regardless of the underlying scheduler type.

Management

The structure captures:

  • CPU allocation (cores, tasks, nodes)

  • Memory allocation (total and per-node limits)

  • Job identification and queue information

  • Resource limit flags for validation

Usage

This structure is populated by JobSchedulerDetector and used throughout the application to make resource allocation decisions that respect cluster limits and prevent resource conflicts.
