Get started here¶
In order to use UPPMAX resources, you need to be a member of a project and a user account.
PIs¶
Do you or members in your research group need compute and storage resources on a HPC cluster or Infrastructure-as-a-Service cloud? Learn how to apply for a project by following the link below.
Are you interested in other services, e.g. large volume data storage?
Let us know by contacting UPPMAX Support at support@uppmax.uu.se!
Users¶
Once you or someone in your group or collaboration has a project, you must apply for a user account by following the link below.
Have an account already? Then check out these basic user guides:
Students¶
Are you taking a university course that uses UPPMAX and need help? Ask your instructor! If they can't help, contact us through IT Support.
Getting started: First login to UPPMAX¶
See Log in to an UPPMAX cluster.
Changing your password¶

Copying files from/to your UPPMAX account¶

Where are my files? (Or, what are the different file systems?)¶
You have access to the same home directory regardless of what cluster you have logged into. Here you store your private files.
All projects also have a central storage area under the /proj/[project id]/ directory path. I.e. when you first login to UPPMAX you will see your home directory, so you will have to change to the project directory if you want to transfer project data files.
Also note that UPPMAX uses different disk quotas on your home directory and other areas you have access to (like the project folder).
Example: to see who much disk space you use:
uquota
We have a page with more information about different file storages and quotas that can be good to read.
Your private files¶
When you log in to UPPMAX for the first time you only have the following files created by the system:
ls -la
total 68
drwxr-x--- 7 user uppmax 4096 Jun 2 23:11 .
drwxr-xr-x 19 root root 0 Jun 9 13:16 ..
-rw-r--r-- 1 user uppmax 24 Jan 9 2008 .bash_logout
-rw-r--r-- 1 user uppmax 435 Apr 21 2008 .bash_profile
-rw-r--r-- 1 user uppmax 446 Jan 9 2008 .bashrc
drwxr-xr-x 2 user uppmax 4096 Jan 9 2008 bin
-rw-r--r-- 1 user uppmax 385 Jan 9 2008 .cshrc
-rw-r--r-- 1 user uppmax 237 Jan 9 2008 .emacs
drwxrwxrwx 1 user uppmax 14 Jun 2 11:05 glob
-rw-r--r-- 1 user uppmax 120 Jan 9 2008 .gtkrc
-rw-r--r-- 1 user uppmax 279 Apr 21 2008 .login
drwx--S--- 2 user uppmax 4096 May 2 2008 private
-rw-r--r-- 1 user uppmax 307 Apr 21 2008 .profile
-rw-r--r-- 1 user uppmax 220 Jan 9 2008 .zshrc
The files starting with a "." are hidden files — startup scripts or configuration files.
The default permission of your home directory is 750, i.e. you can do everything, people belonging to the same group can read and execute your files and other people can not do anything. For more info on file permissions see this page on the online Linux Handbook.
Also note the private sub-folder. Here you can put files that you want only you, and no one else, to be able to access. Each day we have a job that ensures that all users's private folders still can't be accessed by anyone else, even if the permissions somehow accidentally would change.
Creating and editing files¶
The nano text editor¶
There are several editors installed at UPPMAX. The one that is considered easiest to use for new users without graphics is nano.
Example: how to use nano:
nano filename
Save and exit the file with:
Control-O, Control-X
(You might need to answer "y" or "n" on some questions, and/or press "Enter" to confirm.)
Exit without saving with:
Control-X
You can get more help with nano by pressing (inside nano):
Control-G
The Emacs text editor¶
Another very common editor, with more features (but a little harder to use), is emacs.
Example: how to use emacs:
emacs filename
Do the editing you want, then save with:
Control-x, Control-s
Exit emacs with:
Control-x, Control-c
You can read a tutorial in emacs by doing:
Control-h t
The Gedit text editor¶
See gedit
Bash, bourne-again shell¶
Bash is the default Unix shell, a command-line interpreter and script host that provides a traditional user interface for the linux operating system at UPPMAX. Users direct the operation of the computer by entering command input as text for a command line interpreter to execute or by creating text scripts of one or more such commands.
The .bash_profile file is run whenever you login or when you start a login shell (as in starting a job in the queue).
The .bashrc file is run when an interactive shell that is not a login shell is started, or if it is called from the .bash_profile (as it is in the default configuration).
The .bash_logout file is run when you log out.
Modules¶
In order to run installed programs, one uses the module system.
How to run jobs¶
All jobs should be run using the job scheduler.
