Through Native acceleration technology, it helps enterprise customers maximize the performance of Java applications in AI big data scenarios.

Installation and Integration

Dragonwell AI-Extension is an extension of Alibaba Dragonwell JDK, itself based on Dragonwell 11.0.30.27.7 or newer versions. You can use the following command to install the latest AI-Extension package:

yum install java-11-alibaba-dragonwell-ai-extension

Usage Guide

AI-Extension supports two parameters:

  • -XX:+UseAIExtension: This parameter is used to enable AI-Extension capabilities. It is currently a preview feature and needs to be used in conjunction with the -XX:+UnlockExperimentalVMOptions option. As the system matures, this option will become an official feature in subsequent versions.
  • -XX:AIExtensionUnit=xxx: This parameter can be used to load specific acceleration libraries designed for different scenarios.

AI-Extension currently supports accelerating Spark 3.5.x on the x86-64 platform. To enable this feature, you can add the following parameters to the Java startup command:

java -XX:+UnlockExperimentalVMOptions -XX:+UseAIExtension -XX:AIExtensionUnit=spark_3.5 ..

Compatibility and Support

Alibaba Dragonwell 11 AI-Extension is developed based on Dragonwell 11 Extended Edition. Dragonwell 11 Extended Edition is a downstream distribution of OpenJDK 11. You can directly use the AI-Extension to run existing JDK 11 applications without any code adaptation or migration.

Alibaba Dragonwell 11 AI-Extension provides Long-Term Support (LTS), and the maintenance cycle remains synchronized with OpenJDK: we will release updated versions every quarter.
