This time, the course is given in the form of a web conference again. If you want to participate, you should make the following preparations":

• sign up for the course as mentioned above
• if you do not have one yet, request an HPC account (if you have problems contact Scientific Computing)
• have a computer connected to the internet available during the time of the course
• you also need speakers or headphones, a microphone is not needed (if you have one, please use headphones to avoid feedback loops). A webcam should not be used as it takes up too much bandwidth.
• your computer should also be able to connect to the HPC cluster, for this you need to install and use the GlobalProtect client to establish a VPN.
• on Windows computers use MobaXterm to login to the cluster, Linux and Mac users can use ssh in a terminal

On Monday, a little before the course starts at 10:15 am, go to the course page in Stud.IP, select the Meetings tab and join the web conference (or use the link before). In the web conference, we will show slides and use audio for the lecturers, you can ask questions in the text chat.
