We are pleased to announce that the Scheduler Microconference has been accepted into the 2019 Linux Plumbers Conference! The scheduler determines what runs on the CPU at any given time. The lag of your desktop is affected by the scheduler, for example. There are a few different scheduling classes for a user to choose from, such as the default class (SCHED_OTHER) or a real-time class (SCHED_FIFO, SCHED_RT and SCHED_DEADLINE). The deadline scheduler is the newest and allows the user to control the amount of bandwidth received by a task or group of tasks. With cloud computing becoming popular these days, controlling bandwidth of containers or virtual machines is becoming more important. The Real-Time patch is also destined to become mainline, which will add more strain on the scheduling of tasks to make sure that real-time tasks make their deadlines (although, this Microconference will focus on non real-time aspects of the scheduler. Please defer real-time topics to the Real-time Microconference). This requires verification techniques to ensure the scheduler is properly designed.

Topics for this year include:

• Load Balancer Rework – a prototype
• Idle Balance optimizations
• Core scheduling
• Proxy Execution for CFS
• Improving scheduling latency with SCHED_IDLE task
• Scheduler tunables – Mobile vs Server
• Removing the tick (NO_HZ and NO_HZ_FULL)
• Linux Integrated System Analysis (LISA) for scheduler verification

Come and join us in the discussion of controlling what tasks get to run on your machine and when.

We hope to see you there!
