Threadz Thread Pool Library

Description

This is a thread pool library that you can do two main things with, which I'll demonstrate in code:

# These are more for "fire and forget" tasks
T1 = Threadz::ThreadPool.new
T1.process { puts "my first task" }
T1.process { puts "my second task" }

# If you care when the tasks complete, use batches
T2 = Threadz::ThreadPool.new
b = T2.new_batch
b << lambda { puts "my first task" }
b << lambda { puts "my second task" }

puts "do a couple of other things..."

b.wait_until_done

# You can do other things, too

T3 = Threadz::ThreadPool.new
b = T3.new_batch
b << lambda { puts "my first task" }
b << lambda { puts "my second task" }

puts "do a couple of other things..."

b.when_done { puts "woohoo, done with tasks" }

puts "and some other stuff, blah"

b = T3.new_batch
b << lambda { 10000000.times {} }

b.wait_until_done(:timeout => 0.1)
puts b.completed? ? "finished!" : "didn't finish"

The thread pool is also smart – depending on load, it can either spawn or cull additional threads (at a rate you can set).

Examples

For examples, please see the well-documented specs. They're all fairly simple and straightforward. Please message me if they're not.

Disclaimer

Consider this product in late alpha. There are still some bugs to be worked out and the API may change.
