We used the average performance criticality of tasks as a threshold to determine the proper core type (big or little). However, if the big core's compute capacity is not half of the total compute capacity, such an average-based determination becomes suboptimal. If fewer tasks are classified as performance-critical tasks and requested to run on big cores, the big cores would be wasted by stealing arbitrary non-performance-critical tasks. That could result in performance instability. Hence, determine the threshold more accurately by considering (active) big cores' compute capacity and the (approximated) distribution of performance criticality of tasks.

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.
