Simulation method and device for virtual tasks in sandbox environment under NUMA architecture

Abstract

The invention discloses a simulation method and device for virtual tasks in a sandbox environment under an NUMA architecture. The method comprises the steps that based on tasks in a preset task test set, corresponding task parameters are adjusted to synthesize the virtual tasks of a specific type or virtual task combinations composed of the tasks of multiple types; the tasks of multiple types and multiple task combinations running simultaneously are contained in the task test set; the virtual tasks or the virtual task combinations are run in the sandbox environment, and fingerprints and scheduling policies corresponding to all the virtual tasks are obtained and stored into an experience database; and configuration of the sandbox environment is the same as configuration of a production environment. Obviously, through the simulation method and device, all the tasks in the needed types can be run as soon as possible in the sandbox environment, the task running conditions are determined, the corresponding fingerprints and scheduling policies under all the types are obtained, and the efficiency of a simulation test is improved.

Description

technical field [0001] The invention relates to the technical field of NUMA architecture application, in particular to a virtual task simulation method and device thereof in a sandbox environment under the NUMA architecture. Background technique [0002] There are multiple memory nodes (memory nodes) in the NUMA (Non Uniform Memory Access Architecture, non-uniform memory access architecture), each memory node and its corresponding multi-core system constitute a memory domain (memory domain), each memory domain has Independent and private memory controller. [0003] In order to confirm the scheduling strategy that needs to be assigned to various tasks under the NUMA architecture, it is necessary to simulate the tasks, usually based on the real tasks currently running. However, due to the uncertainty of various types of situations in the real tasks, it is only The running conditions of all types of tasks cannot be quickly determined based on real tasks, and the efficiency of ...
