![]() ![]() These are important concepts for this article: You can find a general summary in Hyper-V Technology Overview. Understanding how Hyper-V virtualizes processorsīefore considering hypervisor scheduler types, it's also helpful to understand the Hyper-V architecture. Intel refers to their SMT offerings as Intel Hyper Threading Technology, or Intel HT.įor the purposes of this article, the descriptions of SMT and how it is utilized by Hyper-V apply equally to both Intel and AMD systems.įor more information on Intel HT Technology, refer to Intel Hyper-Threading Technologyįor more information on AMD SMT, refer to The "Zen" Core Architecture ![]() Processors supporting SMT are available from both Intel and AMD. SMT generally offers a modest performance boost to most workloads by parallelizing computations when possible, increasing instruction throughput, though no performance gain or even a slight loss in performance may occur when contention between threads for shared processor resources occurs. Simultaneous multithreading, or SMT, is a technique utilized in modern processor designs that allows the processor's resources to be shared by separate, independent execution threads. Backgroundīefore discussing the logic and controls behind Hyper-V virtual processor scheduling, it's helpful to review the basic concepts covered in this article. Updates are required to use the hypervisor scheduler features described in this document.
