The scheduler is an important functionality of the Linux kernel, deciding what
process gets to run when, where, and for how long. With different topologies and
workloads, it is no easy task to give the user the best experience possible.
Schedulers are one of the most discussed topics on the Linux Kernel Mailing
List, but many of these topics need further discussion in a conference format.
Indeed, the scheduler microconference is responsible for many topics to make
progress.
At last year's meet up, the Scheduler microconference achieved the following
results:
- Core scheduling was merged! [1]
- Scheduling fairness patches have been merged [2]
- Fixes to NUMA topology limitations[3]
Not only were enhancements made, but the meet-up also helped prove that some
topics were not feasible and we do not need to spend more time on them [4].
Some possible topics for this year are:
- Cgroup interface and other updates for core-scheduling [1]
- Cgroup and SCHED_DEADLINE [5]
- Capacity Awareness – For busy systems
- Interrupt Awareness
- Load Balancing:
- Wakeup [6] [7] [8]
- Periodic [6] [7]
- NUMA load balancing
If you are interested in participating in this microconference and have topics
to propose, please use the LPC CfP process, and select "Scheduler MC" for the
"Track". More topics will be added based on CfP for LPC microconference.
The submission deadline is August 31st.
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!
