node-cluster-seed

- A simple seed project for quickly getting started with node-cluster.	

- Current version is tested with Node v0.10.21 and above.

- Presented example uses Express for the worker.

###Descrition on repo contents

1. cluster.js - Main file which is responsible for forking worker processes and managing them. - Contains separate sections for the tasks to be done while in master process and for the tasks to be done while in worker process. - Master process forks workers equal to the number of CPUs in the running environment. - Has configuarable scheduling algorithm setting. - Contains all essential life cycle methods like fork,online,exit,etc., in the master process. - The example presented has a simple tracker module that keeps track of all the HTTP requests received by all workers.

2. worker.js - This file contains all the chores that each worker has to perform when spawn. - In the example presented, each worker reports to master on every incoming request that it receives.

3. enums.js - Helper to hold address type mapper and the similars.

###How to run

• env NODE_CLUSTER_SCHED_POLICY="none" node cluster // to let operating system decide on the scheduling policy

• env NODE_CLUSTER_SCHED_POLICY="rr" node cluster // to force round-robin manually

• node cluster // Naa, I don't care what scheduling policy will be used. ;)

###Todo's

- Write tests
- Add code comments
- Rethink optimizations
