About A-Tune

An operating system (OS) is base software that connects applications and hardware. It is critical for users to adjust OS and application configurations and make full use of software and hardware capabilities to achieve better service performance. However, numerous workload types and varied applications run on an OS, and the requirements on resources are different. Currently, the application environment composed of hardware and software involves more than 7,000 configuration objects. When the service complexity and optimization objects increase, the time required for optimization increases exponentially. As a result, optimization efficiency decreases sharply. Optimization becomes complex and brings great challenges to users.

As infrastructure software, an OS provides a large number of software and hardware management capabilities. The capabilities required vary in different scenarios and need to be enabled or disabled as needed. A combination of capabilities will maximize the optimal performance of applications.

In addition, the actual services embrace hundreds and thousands of scenarios, and each scenario involves a wide variety of hardware configurations for compute, network, and storage. The lab cannot list all applications, service scenarios, or hardware combinations.

To address the preceding challenges, HCE integrates A-Tune launched by openEuler.

A-Tune is an AI-powered engine that optimizes the system to ensure that services can run at optimal performance. It uses AI technologies to precisely profile service scenarios, discover and infer service characteristics, so as to make intelligent decisions, match the optimal combination of system parameter settings, and give recommendations.
