thread_pool_ruby

ThreadPool

A simple ThreadPool that satisfies the following criteria of the thread pool pattern:

1. Semaphores

Passing in an integer that will spin up that number of threads to execute the queue, and no more.

1. Reuse of threads

Threads will not be recreated when a new task needs to be worked on. Thread destruction and creation can be expensive, so reusing Threads is an important part of performance in a thread pool.

1. Threadsafe operations

The threads use a shared queue, which is threadsafe by using the ruby Queue object.

Usage

The first argument is a list of tasks that have to respond to call.

The second argument is the count for the semaphore.

After instantiation, call execute and watch it go!

task = lambda {p "Threading!"}
tasks = [task]
thread_count = 5

pool = ThreadPool.new(tasks, thread_count)

pool.execute

Installation

Add this line to your application's Gemfile:

gem 'thread_pool'

And then execute:

$ bundle

Or install it yourself as:

$ gem install thread_pool

Development

After checking out the repo, run bin/setup to install dependencies. Then, 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 to create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
