1.1 License file

The programs of the ADF package require a license file to run. However, you may already install the package without the license file. In case of a trial version, a trial demo license file is attached to the mail in which you receive the necessary information to download our software. In other cases and this is your first installation of ADF we can, in fact, only make your license file after you have installed the package.

The license file contains information about the machines that your license allows you to use the programs on. You must make this file available with read-access for all users of the program on all the machines the program might be used on. You can do this, for instance, by putting the license file on a shared disk, or by copying the file to all machines. The name of the license file is immaterial: you have to set an appropriate environment variable to reference it.

We recommend the following procedure (if you already have a valid license, you can skip steps 2, 3, and 4):

1. Install the package as described in Chapter 2.

2. Generate the license information with the following command:

$ADFBIN/dirac CHECK

This will note that your license is invalid.

3. SCM needs the full output of the previous command to generate your license file. Send exactly that information to us (email license@scm.com).

4. You will get the license file per e-mail.

5. Pick up the license file and move it to an appropriate location on your machine, corresponding to the environment variable $SCMLICENSE which you should define in your login script (see Chapter 2).

6. Ensure that the permissions on the license file allow read access for all users.

7. Verify that you can now run the sample runs provided with the package and that they give correct results. We recommend that you consult the Examples document for notes on such comparisons: non-negligible differences are not necessarily indicative of an error.

Note: the sample runs are complete run scripts that should be executed as such, not just input files to feed into the program.
