 How much scalability is actually needed is highly debatable.
-\emph{libfibre}\cite{libfibre} has compared favorably to other schedulers in webserver tests\cite{Karsten20} and uses a single atomic counter in its scheduling algorithm similarly to the proposed bitmask.
+\emph{libfibre}\cite{libfibre} has compared favorably to other schedulers in webserver tests\cite{karstenuser} and uses a single atomic counter in its scheduling algorithm similarly to the proposed bitmask.
 As such, the single atomic instruction on a shared cacheline may be sufficiently performant.

 Processors that are unnecessarily unblocked lead to unnecessary contention, CPU usage, and power consumption, while too many sleeping processors can lead to sub-optimal throughput.
 Furthermore, transitions from sleeping to awake and vice-versa also add unnecessary latency.
-There is already a wealth of research on the subject\cite{schillings1996engineering, wiki:thunderherd} and I may use an existing approach for the idle-sleep heuristic in this project, \eg\cite{Karsten20}.
