WitrynaThis leads to the well-known Lock Holder Preemption (LHP) and Lock Waiter Preemption (LWP) issues. In this paper, we propose I-Spinlock (for Informed Spinlock), a new spinlock implementation for virtualized environments. Its main principle is to … WitrynaThen we propose ANOLE, a runtime adaptive lock waiter detection approach for lock holder preemption overhead reduction of MP guests. It leverages the modern hardware feature without any modification to spin lock implementation. ANOLE implements a hyper visor framework to preempt virtual CPUs adaptively and a user agent for guest spin …
