Technical interpretation: 무조건 gang/coscheduling하기보다 IPI 같은 실제 synchronization event를 coordination trigger로 사용하면 utilization 손실을 줄일 수 있다. Demand-Based Coordinated Scheduling for SMP VMs 혼합 PARSEC workloads에서 불필요한 synchronization latency와 CPU 소비를 줄여 전체 성능을 개선했으며, 특히 communication-intensive application에서 효과가 컸다. 공식 초록에는 정량값이 없다. 통신·동기화에 민감한 multithreaded workload를 호스팅하는 SMP VM의 vCPU들을, CPU fragmentation 없이 실제 coordination demand에 맞춰 스케줄할 수 있는가? lab 무조건 gang/coscheduling하기보다 IPI 같은 실제 synchronization event를 coordination trigger로 사용하면 utilization 손실을 줄일 수 있다.
