1.1 Quick Guide

Preparing the execution

1. Get the software and configuration files here.

2. Unzip JGDS and configuration files in an folder.

3. Modify the configuration files to adapt it to your needs. To do this see Section 3 for more details.

Sequential execution

1. In the configuration file of the problem you want to solve set parameters NUM_ISLANDS = 1 and HOST_1 =127.0.0.1 

2. Then uses the command java Island 1 -o <output file> -c <config file> to have a sequential execution. Remember that JGDS directory must appear in CLASSPATH environment variable.

3. Output file will have the results of the execution.

Parallel execution

1. In the configuration file of the problem you want to solve set parameters NUM_ISLANDS  to the number of islands you want to use. Next set parameters HOST_n to the IP address of every hosts. You can repeat IP address. See an example in Section 4.2.

2. Then uses the command java Island <i> -o <output file> -c <config file> in the corresponding host. The Island 1 must be the last executed.
