arrayfire_java

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

• make

  • GNU Make on Linux

• C++ compiler

  • gcc or clang on Linux

• OSX and Windows support coming soon

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

• lib/: The location where the JNI library is stored

• examples: contains a few examples demonstrating the usage

Usage

After you the necessary pre-requisites, edit the following paramets

• Open Makefile and change JAVA_HOME together with AF_PATH to the right location

Linux

• To build the JNI Wrapper for ArrayFire use

  • make cuda to build using CUDA
    • alternatively, you can pass in environment variables to the Makefile like this: JAVA_HOME=<path to the Java SDK> AF_PATH=<path to ArrayFire> make cuda
  • make opencl to build using OpenCL
    • alternatively, you can pass in environment variables to the Makefile like this: JAVA_HOME=<path to the Java SDK> AF_PATH=<path to ArrayFire> make cuda

• To build the examples do one of the following from the examples directory

  • make cuda run to use build and run examples using CUDA
    • alternatively, you can pass in environment variables to the Makefile like this: JAVA_HOME=<path to the Java SDK> AF_PATH=<path to ArrayFire> make cuda
  • make opencl run to use build and run examples using OpenCL
    • alternatively, you can pass in environment variables to the Makefile like this: JAVA_HOME=<path to the Java SDK> AF_PATH=<path to ArrayFire> make cuda
