The new emerging NLE for GNU/Linux

The purpose of the Scheduler is to run small self contained Jobs ordered by priority and observing specific timing constraints.

Scheduler implementation ideas

Use multiple priority queues

  • background work

  • foreground high-priority

  • soft-realtime actions

About Jobs

A job is a closure to run a small and limited action or operation, which in itself should not block. Job may depend on each other and on resources to be provided. A job may be conained in multiple queues and may be marked as canceled — in which case the job function will never run and the job will be discarded on occasion.

Job States

enum job_state
{
  done,         // already done, nothing to do
  running,      // job is running
  waiting,      // waits for some resource (annother job)
  rejected,     // sorry, cant do that dave, time will run out
  expired,      // time expired
  aborted       // got aborted
}
