To have a sequential execution the next command must be used:

> java Island 1 -o output1.txt -c config.txt

In the configuration file we have to specify:

      NUM_ISLANDS = 1

        HOST_1= 127.0.0.1 (if we are running in the local host) or

        HOST_1= <IP address> (if we are running in another host, it's possible to see in the host file /etc/hosts)

        ............ (now put your own problem configuration)
