Gantenbein is a computer at the department of mathematics that provides a dedicated training ground for this course. You must have access to check and submit your assignments. Provided that you successfully registered in Canvas before the course start, you receive account data by email in the first week of the course. If you are registered later contact me.

Log in

If you, for instance, have the user name hpcuser223, you log into gantenbein via

ssh hpcuser223@gantenbein.math.chalmers.se

After that you have a usual terminal to work in. Gantenbein does not allow for a graphical user interface, like all high performance computing environments. Use the terminal as explained on the HPC website on "Command line usage and basic workflow".

Transferring files to and from gantenbein

To submit your solutions to the assignments, you need to transfer files from gantenbein. Should you want to edit files on a different system, which is not recommended, but common and accepted practice among students you will also need means to transfer them to and from gantenbein.

To transfer files you can use the command scp. An alternative command is rsync, which in some situations is more suitable. As an example of copying files from gantenbein to the working directory on your local computer is

scp hpcuserXXX@gantenbein.math.chalmers.se:assignment2/submission.tar.gz .

Note that the command might vary on operating systems different from Linux.

Your operating system

The Linux computers provided by Chalmers provide the crucial commands ssh and scp. Most students, however, prefer to connect to gantenbein from their own machines. There is no need that your system runs Linux as long as it provides those commands.
