Actors in the Small 

JASocket is a lock-free, scalable and robust server framework with no single point of failure. Servers are run on a cluster of nodes. Servers interact with other servers using mobile agents, which reduces the number of messages and thus reduces the overall system latency. Administration is handled via ssh.

Benchmarks:
Latency for agents sent between 2 JVM’s on the same machine (round trip): 84 microseconds.
Throughput for agents sent between 2 JVM’s on the same machine: 137,000 per second.

(Test Machine: i7-3770 @ 3.40 GHz, ASUS P8Z77-M Motherboard, 16 GB Corsair DDR3 1600 MHz RAM and Vertex 3 SATA III SSD)

 
Maven:
JASocket is available on The (Maven) Central Repository, so Maven users just need to add this to their POM file:

<dependency>

    <groupId>org.agilewiki.jasocket</groupId>

    <artifactId>jasocket</artifactId>

    <version>3.2.1.0</version>

</dependency> 

 
(Be sure to update the version number appropriately, of course.)

Dependencies: Java 7, sshd, jline, joda-time, slf4j, JActor, JID

2. Getting Started with JASocket
   To run JASocket you will need the JAR files for compatible versions of JActor, JID and JASocket. Download these projects from… more
3. Configuring JASocket
   The Node class provides a default configuration for a node in the cluster and also has a main method for running a simple node, e.g. a node without a console. Configuring a node is a matter of… more
4. A Basic Console for JASocket
   The Console class provides JASocket with a basic console. It starts up a node and then repeatedly reads lines of text from System.in and evaluates them using EvalAgent. Here is the code… more
