Home directories are shared among hood/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 users that will set the correct paths by checking the current 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 correct paths on all four 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 (assuming you use bash) 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.

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