Interprocess communication between multiple nodejs apps

I am working on a project in which I am using nodejs. Project runs multiple nodejs apps(processes) simultaneously. I want share data between these processes and synchronize their execution. Does nodejs has something similar to "message queue" and "Semaphores" to share data and synchronize execution of process. I know nodejs has asynchronous I/O and I should't be using blocking I/O operations in my app but some file read/write operations in the app needs blocking I/O.

I can use socket.IO for information sharing but synchronization using socket.io gets messy.

In-short, I am looking for a node module which can host a shared message queue for IPC and also act as a scheduler to block and run processes in the app.

Any help will be appreciated. Thank You.
