-# Dummy players for labs
+# Dummy players for lab
+ Simple example program to demonstrate the usage.
 
 
-## Files:
+### Setting up the **MPI** environment on host para
+ - login to para
+ - `module load mpi`
 
 
-player.h, player.cpp :
- - Player's basic class. Implementing server communication.
-
-main.cpp :
- - Implements a simple burglar and cop players.
- They are moving randomly and create log messages in \*.log files.  
-
-test.sh :
- - Test script for the simple players version.
-
-mpimain.cpp :
- - Simple MPI communication example.
- The silly policeman is moving randomly and shouting to his radio if he sees the robber.
- The others can hear this, but they don't know where the robber is.
-
-mptest.sh :
- - Test script for the MPI version. Starts a burglar, and starts the MPI processes.

-## Compile:
-
- module load mpi  
+### Compile:
  make 
  make 
 
 
-## Starting the clients:
+### Starting the clients from the *client* directory
  ./test.sh – simple version  
  ./test.sh – simple version  
  ./mpitest.sh – mpi version  
  ./mpitest.sh – mpi version  
   
   
-## Starting the graphical server on the local machine:
-1. Creating TCP tunnel between the remote machine (para) and the local host.
+### Starting the graphical server on the local machine:
+- download the server
+ - server.bat - on **WinX** host
+ - ./server.sh on **Unix/Linux** platform
 
 
-  The server listens on port number 15623.   
-  The client uses the unique port number UID+17000, where UID is your user id on host para.
+### Creating TCP tunnel
+A tcp tunnel sholud be set up between the remote machine (para) and the local host.   
+Parameters: 
+- The server listens on port number 15623.
+- The client uses the unique port number UID+15000, where UID is your user id on host para.
+- ./test.sh displays the port number
   
   
-  Using putty:  
+#### Tunnel setup using putty  
     Session->SSH->Tunnels  
     Session->SSH->Tunnels  
-    X Local ports accept connection from othrer hosts  
-    Source port: your unique port number (UID+17000). (./test.sh will display the port number  
+    Source port: your unique port number (UID+17000).   
     Destination: localhost:15623  
     Destination: localhost:15623

     Add  
 
 
-  Using ssh
+#### Tunnel setup using ssh
+ `ssh -R **PORT*:localhost:15623 USER@PARA`
+- where **PORT** is your unique port number
+- **USER** is ypur login name on para
+- **PARA** is the hostname of para cluster
