Java wrapper for ArrayFire

arrayfire-java

Slack Channel

This repository contains the files required to use ArrayFire from Java.

Prerequisites

• The latest version of ArrayFire. You can get ArrayFire using one of the following:

  • Download binary installers
  • Build from source

• The latest version of JAVA SDK. It has been tested with OpenJDK 1.7 and OpenJDK 1.8. Make sure there is an environmental variable JAVA_HOME pointing to the root directory of java sdk installation.

• CUDA

  • Tested for CUDA 7.5

• CMake, minimum version of 2.8.

  • On Linux/OSX, it defaults to standard makefiles.
  • On Windows, we have tested with NMake Makefiles.

Contents

• src/: Contains the source files for the ArrayFire Java wrapper

  • *.cpp The JNI wrapper files
  • jni_helper.h The JNI API helper functions

• com/: Contains the Java source files implementing algorithms

• examples: contains a few examples demonstrating the usage

Usage

After you the necessary pre-requisites, do the following:

• mkdir build
• cd build
• Configure and generate the platform specific make files.
  • cmake .. on Linux/OSX
  • cmake -G "NMake Makefiles" .. on Windows from visual studio x64 command prompt.
• Build the project and run helloworld example.
  • make && make exHelloWorld on Linux/OSX.
  • nmake && nmake exHelloWorld on Windows.

Documentation

• TODO

• Please check the LICENSE file in the root directory

arrayfire-java's Issues

Investigate supporting JavaCPP

More details here:
arrayfire/arrayfire#155

Integrate with the new C API from ArrayFire

This will be closed when we have feature parity with 3.2

Can't compile on windows
