Red Arrow CUDA - Apache Arrow CUDA Ruby
Red Arrow CUDA is the Ruby bindings of Apache Arrow CUDA. Red Arrow CUDA is based on GObject Introspection.
Apache Arrow CUDA is an in-memory columnar data store on GPU.
GObject Introspection is a middleware for language bindings of C library. GObject Introspection can generate language bindings automatically at runtime.
Apache Arrow CUDA GLib is a C wrapper for Apache Arrow CUDA C++. GObject Introspection can't use Apache Arrow CUDA C++ directly. Apache Arrow CUDA GLib is a bridge between Apache Arrow CUDA C++ and GObject Introspection.
gobject-introspection gem is a Ruby bindings of GObject Introspection. Red Arrow CUDA uses GObject Introspection via gobject-introspection gem.
Install Apache Arrow CUDA GLib before install Red Arrow CUDA. Use packages.red-data-tools.org for installing Apache Arrow CUDA GLib.
Note that the Apache Arrow CUDA GLib packages are "unofficial". "Official" packages will be released in the future.
Install Red Arrow CUDA after you install Apache Arrow CUDA GLib:
% gem install red-arrow-cuda
require "arrow-cuda" manager = ::.new if manager.n_devices.zero? raise "No GPU is found" end context = manager buffer = ::Buffer.new(context, 128) ::BufferOutputStream.open(buffer) do |stream| stream.write("Hello World") end puts buffer.copy_to_host(0, 11) # => "Hello World"
