r264f6c9 r62424af2 12 12 13 13 This thesis analyses multiple scheduler systems, where each system attempts to fulfill the requirements for \gls{uthrding}. 14 The predominant technique for managing high levels of concurrency is sharding the ready -queue with one queue per kernel-thread and using some form of work stealing/sharing to dynamically rebalance workload shifts.14 The predominant technique for managing high levels of concurrency is sharding the ready queue with one queue per kernel-thread and using some form of work stealing/sharing to dynamically rebalance workload shifts. 15 15 Preventing kernel blocking is accomplished by transforming kernel locks and I/O operations into user-level operations that do not block the kernel thread or spin up new kernel threads to manage the blocking. 16 16 Fairness is handled through preemption and/or ad-hoc solutions, which leads to coarse-grained fairness with some pathological cases.
