To have a sequential execution the next command must be used:
>
java Island 1 -o output1.txt -c config.txt
> 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=
............ (now put your own problem configuration)
