Yes there is an open source project on git called Threads a gogo written for node.
TAGG: Threads à gogo for Node.js
Threads à gogo (*) is a native module for Node.js that provides an asynchronous, evented and/or continuation passing style API for moving blocking/longish CPU-bound tasks out of Node's event loop to JavaScript threads that run in parallel in the background and that use all the available CPU cores automatically; all from within a single Node process.
Installing the module
With npm:
npm install threads_a_gogo
From source:
git clone http://github.com/xk/node-threads-a-gogo.git
cd node-threads-a-gogo
node-gyp rebuild
# It also works with node-waf, but this is outdated, so please use node-gyp nowdays.
To include the module in your project:
var threads_a_gogo= require('threads_a_gogo');
