CPU SCHEDULER CONFIGURED TO SUPPORT LATENCY SENSITIVE VIRTUAL MACHINES

摘要

A host computer has one or more physical central processing units (CPUs) that support the execution of a plurality of containers, where the containers each include one or more processes. Each process of a container is assigned to execute exclusively on a corresponding physical CPU when the corresponding container is determined to be latency sensitive. The assignment of a process to execute exclusively on a corresponding physical CPU includes the migration of tasks from the corresponding physical CPU to one or more other physical CPUs of the host system, and the directing of task and interrupt processing to the one or more other physical CPUs. Tasks of the process corresponding to the container are then executed on the corresponding physical CPU.

主权项

1. A method for assigning processing resources to a plurality of containers, the method comprising:
determining that a first container of the plurality of containers is deemed to have a high level of latency sensitivity; responsive to determining that the first container is deemed to have the high level of latency sensitivity, affording the first container exclusive affinity to a first PCPU of a plurality of PCPUs; and due to the first container having exclusive affinity for the first PCPU, refraining from scheduling one or more tasks of containers of the plurality of containers other than the first container, to the first PCPU, when the first PCPU is idle.
