scx_mitosis is a dynamic affinity scheduler which assigns cgroups to Cells and Cells to discrete sets of CPUs. The number of cells is dynamic as is the CPU assignment. BPF mostly just does vtime scheduling for each cell, tracks load, and responds to reconfiguration from userspace. Userspace makes decisions about how to assign cgroups to cells and cells to cpus. This is not yet a complete scheduler, much of the userspace logic is a placeholder as I experiment with better logic. I also want to add richer scheduling semantics to userspace, e.g. so that cells can do more "soft-affinity" rather than the strict partitioning implemented currently.

RUST SCHEDULERS
Introduction
This directory contains schedulers with user space rust components.
The README in each scheduler directory provides some background and describes the types of workloads or scenarios they're designed to accommodate. For more details on any of these schedulers, please see the header comment in their main.rs or *.bpf.c files.
