Xtend vs OpenCL: What are the differences?

Developers describe Xtend as "Flexible and expressive dialect of Java". It is a flexible and expressive dialect of Java, which compiles into readable Java 8 compatible source code. You can use any existing Java library seamlessly. The compiled output is readable and pretty-printed, and tends to run as fast as the equivalent handwritten Java code. On the other hand, OpenCL is detailed as "The open standard for parallel programming of heterogeneous systems". It is the open, royalty-free standard for cross-platform, parallel programming of diverse processors found in personal computers, servers, mobile devices and embedded platforms. It greatly improves the speed and responsiveness of a wide spectrum of applications in numerous market categories including gaming and entertainment titles, scientific and medical software, professional creative tools, vision processing, and neural network training and inferencing.

Xtend and OpenCL can be primarily classified as "Language Extensions" tools.

Some of the features offered by Xtend are:

• Works great on Android
• Advanced support for code generation
• Works well with Java 8 APIs

On the other hand, OpenCL provides the following key features:

• Cross-platform
• Parallel programming
• Improves the speed and responsiveness
