PArray

Parallelized array which executes each block concurrrently in enumerable operations

Add this line to your application's Gemfile:

gem 'parray'

And then execute:

$ bundle

Or install it yourself as:

$ gem install parray

By using parallelize, you can convert enumerable objects into parallelized arrays. In enumerable operations, parallelized arrays use multiple threads to execute each block concurrently. The default size of threads is 2.

[1] pry(main)> include PArray::API

[2] pry(main)> a = parallelize([1, 2, 3])
=> #<PArray:0x00007fd786872840 @arr=[1, 2, 3], @in_threads=2>

[3] pry(main)> a.map { |i| sleep(rand); p i; i * 2 }
2
3
1
=> [2, 4, 6]

You can also use PArray.parallelize to convert enumerable objects.

[1] pry(main)> a = PArray.parallelize([1, 2, 3])
=> #<PArray:0x00007fd7863283a8 @arr=[1, 2, 3], @in_threads=2>

After checking out the repo, run bin/setup to install dependencies. Then, run rake true to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
