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

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

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

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

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
