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.

# Since meson and cargo tries build in parallel, this can cause significant load
|
|
# when meson tries to launch N instances of cargo and cargo tries to compile N files
|
|
# in parallel (N*N compiler instances in total).
|
|
#
|
|
# To prevent this from happening, we try to force meson to build them sequentially
|
|
# by making the "current" scheduler depend on another scheduler.
|
|
# To add a new scheduler, assign the output of your custom_target to sched
|
|
# and add sched as a dependency to your custom_target. For example:
|
|
#
|
|
# sched = custom_target('scx_mysched',
|
|
# ...
|
|
# depends: [mydep, sched],
|
|
# build_always_stale: true)
