How to message between CPU Cores in Node?

Question

I have an application that I'm working on that needs to sync a timer between multiple cores (using cluster).

Is there an efficient reliable way that I can communicate between cores? I've looked at Redis, but that seems to be more geared towards client/server communication. I'd be grateful for any advice.

Thank you,

You need to take a look at hook.io:

hook.io creates a distributed node.js EventEmitter that works cross-process / cross-platform / cross-browser. Think of it like a real-time event bus that works anywhere JavaScript is supported.

All good answers. I'm going to go with hook.io since it's very well documented. – Eric Clifford Nov 07 '11 at 18:08
Too bad hook.io died... Anyone found a replacement? – balupton Feb 15 '13 at 16:52

Look at message queue services such as ZeroMQ. They have advantage of supporting both local IPC and TCP transports, so you are ready for horizontal scalability beyond cores available on a single cloud node. zmq has a binding for node.

RabbitMQ is also awesome. Also pub/sub with redis, or just socket.io – CamelCamelCamel Nov 05 '11 at 02:16
Using ZeroMQ is a very bad idea, performance suck. This is due to the JS wrapper. – kilianc Nov 06 '11 at 10:21

Take a look at https://github.com/substack/dnode You can use it to communicate between nodejs processes.
