Login script

Home directories are shared among hood, bow, minnewanka, waterton, kesagami, kuujjua, thelon, winisk, kazan. If your account uses bash for its login shell on all of these machines, then they will run the same bash login script (such as .profile, .bash_profile). Similarly if your account uses csh (or tcsh) they will run the same csh login script (.cshrc).

This is a Good Thing, except that some paths differ between the systems. Below is some code for bash and csh users that will set the recommended environment for each system.

As of September 2016, all new accounts created on hood will have .cshrc and .profile files that are already set up this way so no special steps are needed, and you'll have the recommended paths on all systems.

If your account is older than that, you have two options:

1. You can run the command "init_home" on hood to get the new .cshrc and .profile files. Your old .cshrc and .profile get renamed, so you can reintegrate from them whatever other customizations you might have made. (This is a good choice if you have made few or no changes to your .cshrc or .profile previously.)
2. You can edit your existing $HOME/.bash_profile or $HOME/.cshrc to include the following code. (This is a good choice if you have already customized your .cshrc or .profile a lot.)

Note that the SPINS set-up file for hood relies on these settings for Intel compilers and OpenMPI libraries. Similarly the recommended MITgcm set-up files rely on these recommended settings as well.

If any of these paths change, please update this wiki page.
