To connect to several servers

Question

Hi,
I must make an application that calculates the number pi. Points will be created at random and will use the circle unit.
The user will say to the client the number to him of points that wishes to generate.
So, the client t will receive that number and it will distribute them between several servers. The servers will make the calculations (must work simultaneously) and will give back the result to client. Finally the client will gather the data that have provided the servers to him and will show the final value of pi.
The number of servers is a parameter that will fix at programming, but that must easily be modifiable.
I have read about a server and several clients; but now it's just the inverse.
How I can create several servers simultaneously? How I can connect a client to several servers so that these make the calculations simultaneously?
Any idea? Any reference?
I'm using something like that:
import java.io.*;
import java.net.*;
class Client {
  static final String HOST = "localhost";
  static final int PORT=5000;
  public Client( ) {
    try{
      Socket skClient = new Socket( HOST , Port );
      InputStream aux = skClient.getInputStream();
      DataInputStream flux = new DataInputStream( aux );
      System.out.println( flux.readUTF() );
      skClient.close();
    } catch( Exception e ) {
      System.out.println( e.getMessage() );
  public static void main( String[] arg ) {
    new Client();
import java.io.* ;
import java.net.* ;
class Server {
  static final int PORT=5000;
  public Server( ) {
    try {
      ServerSocket skServer = new ServerSocket( PORT );
      System.out.println("Listening at port " + PORT );
      Socket skCliente = skServidor.accept(); // Crea objeto
     /* CODE CALCULATE */
   } catch( Exception e ) {
      System.out.println( e.getMessage() );
  public static void main( String[] arg ) {
    new Server();
}Thanks a lot

Here is a screenshot of the SEP log showing the connection.
I've disabled all items in this link:

So, it this connection embedded in firefox source code?
Is google collecting firefox user statistics?
