Abstract

A technique for simultaneous multithreading (SMT) by a computer is provided. An operating system or a second-level hypervisor of the computer manages a logical core configuration for simultaneous multithreading. The operating system or the second-level hypervisor has control over a logical core and control over logical threads on the logical core. The operating system or the second-level hypervisor of the computer configures a host hypervisor to assign an entirety of the logical core to a single physical core, such that one logical core executes per physical core. The logical core is run on the single physical core on an exclusive basis for a period of time, such that the logical threads of the logical core execute on physical threads of the single physical core.
