Ubuntu Amazon DCV issues

When running Gnome Terminal over a Amazon DCV session on Ubuntu, you might not automatically have access to the user environment that AWS ParallelCluster makes available through the login shell. The user environment provides environment modules such as openmpi or intelmpi, and other user settings.

Gnome Terminal's default settings prevent the shell from starting as a login shell. This means that shell profiles aren't automatically sourced and the AWS ParallelCluster user environment isn't loaded.

To properly source the shell profile and access the AWS ParallelCluster user environment, do one of the following:

• Change the default terminal settings:

  1. Choose the Edit menu in the Gnome terminal.

  2. Select Preferences, then Profiles.

  3. Choose Command and select Run Command as login shell.

  4. Open a new terminal.

• Use the command line to source the available profiles:

  $ source /etc/profile && source $HOME/.bashrc
