Abstract

Embodiments of the present invention provide a system, method, and program product for domain based resource isolation in multi-core systems. A computing device determines an operation being attempted on a workload request identified with a first domain identifier. The computing device determines a processor core identified with a second domain identifier. In response to determining that processor cores identified with the second domain identifier can service workload requests identified with the first domain identifier, the computing device deploys the workload request to the processor core for servicing.

Description

technical field [0001] The present disclosure relates generally to the field of multi-core processing systems, and more particularly, to workload request dispatching in multi-processing systems. Background technique [0002] The key task of the operating system is to allocate hardware resources, such as processor cycles and memory, to all applications. Typically, applications receive a more or less equal share of resources. In certain situations, it may be desirable to give several applications access to resources over others, such as to meet a desired quality of service. In other cases, it is desirable to limit resources consumed by applications, such as to avoid denial of service attacks. [0003] General-purpose operating systems meet these goals in different ways. One solution supports the concept of priorities and limits by process. Another solution groups tasks by an arbitrary attribute such as user ID and imposes a limit on the resources consumed by all tasks in t...
