Jades

This Java library provides the class DistributedExecutorService which implements java.util.concurrent.ExecutorService.
The goal is to distribute tasks across a network of machines (nodes) over SSH.

The API is designed to be as user-friendly as possible :
1. Instantiate DistributedExecutorService
2. Add nodes
3. Submit tasks

The only requirement is that all machines have SSH and a compatible JRE (>= 6). More precisely, when a node is added, the application’s jar is automatically copied (scp) to the node and a new server started (ssh).
Handling of access restrictions is left to the user (ie you can type your password every time or use authentication keys).

Nodes can be added dynamically. When a node is added, workers are created according to the node’s processor count. Eg, a cluster of 4 quadcores will give 16 workers.
