First, you must set up your environment so Legion can function properly and locate the executable it needs. Either line can be added to your .cshrc, .kshrc, .bashrc depending on your shell. The login object is your proxy to the world, and Legion generates a certificate that identifies who you are. Now you're ready to try some of the UNIX-like Legion commands to query Legion's context space . The following command will display various Legion objects such as host objects, class objects and vaults.
Legion provides tools for compiling a program and registering it for multiple architectures.
Using Globus Tools Globus, like Legion, also provides a set of higher-level tools to allow you to generate a certificate, stage files, run programs on remote machines, and find out static and dynamic information about various machines that Globus has been deployed on. See Chapter 3 for more information. The examples here will focus on using a few of the Globus tools. In order to use Globus, you first need to get a Globus certificate. Getting a Globus certificate takes several days so allow sufficient time for this step.
