Distributed prime number searcher.

It connects to a number of remote number checker services, sends them a number to check for primeness and accumulates the results.

To build the project, execute:

mvn clean compile assembly:single

To start the checker execute:

java -jar <jar_file> <remote_host_1> <remote_port_1> <remote_host_2> <remote_port_2>

where <jar_file> is the packaged jar of the application, and <remote_host_N> and <remote_port_N> are the respective remote hosts and ports of the remote services that will check given numbers for primeness.

To start an example prime number checker service execute:

java -cp <jar_file>  primenumberservice.PrimeNumberService <port_number>

where <port_number> is the local port number on which the service should start.

Prime numbers are persisted in the primes.dat file. Should the service crash, best effort would be made to recover the last known prime number and continue from there.
