PrimeCruncher: A Prime Number Finding Service Java P2P Unleashed (Sams, 2002) 1. Description PrimeCruncher defines a JXTA service that computes a list of prime numbers between two integers in a distributed manner. This implementation uses the Java JXTA bindings, and is defined in the Java class PrimePeer. A client of this service is also provided, specified in the class PrimeClient. That client asynchronously discovers peers that advertise the prime number searching service via JXTA ModuleSpecAdvertisements. When a user specifies two integers, the client program distributes the task of calculating prime numbers between those integers among all the PrimeCruncher peers it knows of at the time of a job's submission. The client opens a JXTA pipe to each such peer, and sends each a message containing a peer's segment boundary integers. That message also contains the client's PipeAdvertisement to allow the prime searching peer to send its response back to the requesting peer. A prime searching peer computes the list of primes between those boundary numbers, opens a JXTA pipe back to the requesting peer, and sends a response message containing the result as a comma-separated integer list. The client peer waits for all peers to send back their responses, and it then assembles the complete primes list from the partial results, and displays that list back to the user. 2. Limitations This example focuses on JXTA programming features, and does not attempt to distribute the computation fairly between peers. Rather, it provides a framework upon which a more sophisticated scheduling mechanism may be built. 3. How to compile and run the examples To compile and run this service with the included Ant build file, you need to have the following software installed: * JDK 1.3 or higher * JXTA Java binding * Ant 1.4 or higher The JDK may be downloaded from http://java.sun.com. You may obtain the most up-to-date JXTA release from http://www.jxta.org, and the current Ant distribution from http://jakarta.apache.org. Once you've installed these packages (installation instructions for each package are available at their respective Web sites), you can use Ant to compile and run the service. To build the classes from the source directory, open a command window on your favorite operating system, and type: > ant To build the documentation, type: > ant javadoc To run the service, enter: >ant runservice To run another instance of the service (to simulate a multi-machine environment), type: >ant runservice2 Finally, to run the client, enter: >ant runclient 4.
