1.7 SEAMCAT software

1.7.1 Installation using .jar package
SEAMCAT is an open source project developed using Java which means it can run on any operating system supported by Java. The SEAMCAT installation is started by clicking on the install link from www.seamcat.org and it is free of charge. 
 The .jar package is platform independent so that you can run SEAMCAT on either Mac OS, Linux or Microsoft Windows operating systems. You need to check on the website that you have the latest version installed. 
 It is required that you have the Java runtime environment (JRE) installed on your computer, available to download free of charge from www.java.com . The latest version is recommended.

1.7.2 SEAMCAT home directory and configuration panel
When SEAMCAT (5 and upward) is run, a folder (SEAMCAT home directory) will be automatically created so that every time a new version of SEAMCAT is run, a subfolder with the version number will be created as shown in Figure 14.

1.7.3 Java source code
 The source code for SEAMCAT is made available for scrutiny. The only condition for obtaining a copy of the source code is to sign a special Source Code User Licence Agreement and deliver it to ECO by email ( seamcat@eco.cept.org ). The procedure is described at: http://www.cept.org/eco/groups/eco/seamcat-source-code . 

1.7.4 Multi processing power in SEAMCAT
As of version 5, SEAMCAT is able to run in multiprocessor environments to increase the computation speed. The more processors a computer has, the less time a simulation will take. Since the Monte Carlo simulation method considers that each event is independent from each other, events can therefore be distributed across all the processor cores in the machine in order to decrease the computation time. The EPP runs in parallel for each event.
