scx-rustland

scxrustland is Linux scheduler made of a BPF component (dispatcher) that implements the low level sched-ext functionalities and a user-space counterpart (scheduler), written in Rust, that implements the actual scheduling policy.

In order to use scxrustland you need to install the latest Ubuntu kernel from this ppa: https://launchpad.net/~arighi/+archive/ubuntu/sched-ext

Please ensure that the following interfaces are connected to grant the scheduler complete resource access:

 sudo snap connect scx-rustland:process-control

 sudo snap connect scx-rustland:system-observe

 sudo snap connect scx-rustland:system-trace

Also make sure that compaction kthread does not reclaim unevictable memory to improve scheduler's stability:

 echo 0 | sudo tee /proc/sys/vm/compactunevictableallowed

The scheduler is designed to prioritize interactive workloads over background CPU-intensive workloads. For this reason the typical use case involves low-latency interactive applications, such as gaming, video conferencing and live streaming.
