arrayfire/arrayfire-lua: Lua wrapper for ArrayFire

ArrayFire is a high performance library for parallel computing with an easy-to-use API. It enables users to write scientific computing code that is portable across CUDA, OpenCL and CPU devices. This project provides Lua bindings for the ArrayFire library.

The wrapper is currently compliant with ArrayFire 3.2 API (and higher). If you find any bugs, please report them here.

local AF = require("arrayfire")

AF.main(function()
      local x = AF.randu(5, "f32")
      AF.print("x", x)
      AF.print("min of x", AF.min(x))
      AF.print("max of x", AF.max(x))
end)

TODO

• cmake
• Visual Studio on Windows, clang / gcc on Linux / OSX.

You can install ArrayFire using one of the following two ways.

• Download and install binaries
• Build and install from source

Post Installation Instructions

• Please read the wiki page for setting up the proper environment variables.

Windows

1. Launch cmake-gui. Set source and build directories.
2. Press configure.
3. Select generator as Visual Studio 12 2013 Win64.
   • You can choose a different generator as long as it is Win64.
4. Set CMAKE_INSTALL_PREFIX to a location of choice.
5. Press generate. The generated visual studio solution file will be present in the build directory.
6. Open the VS solution file and build the INSTALL project.

Linux / OSX

1. Make sure the environment variable ArrayFire_DIR is set to /path/to/arrayfire/share/ArrayFire/cmake.
2. Create a build directory and cd into it.
3. Run cmake /path/to/arrayfire-lua/ -DCMAKE_INSTALL_PREFIX=package.
4. Run make

Windows

> SET LUA_PATH=C:\path\to\install\location\arrayfire\?.lua;;
> SET LUA_CPATH=C:\path\to\install\location\?.dll;;
> lua.exe helloworld/helloworld.lua

Linux

$ export LUA_PATH="/path/to/install/location/arrayfire/?.lua;;"
$ export LUA_CPATH="/path/to/install/location/?.so;;"
$ lua helloworld/helloworld.lua

You should now be good to go!

This is a work in progress and is not intended for production use.

This project began with significant contributions from Steven Johnson. It is currently being maintained by @arrayfire/lua-devel team.
