Hands-On

The course revolves mainly around the hands-on sessions, as the point is to enable the users to operate the provided applications.
The sessions will be done on the CooLMUC2 Cluster @ LRZ with 28-way Haswell-based nodes and FDR14 Infiniband interconnect.

Please bring your own laptop with X11 support and an ssh client installed for the hands-on sessions. There are no PCs installed in the course room!

Under Windows
- We recommend to install the comfortable tool MobaXterm (https://mobaxterm.mobatek.net/download-home-edition.html) which also includes an X11 client.
- Alternatively install and run the Xming X11 Server for Windows: https://sourceforge.net/projects/xming/ and then install and run the terminal software putty: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
Under macOS
- Install X11 support for macOS XQuartz: https://www.xquartz.org/
Under Linux
- ssh and X11 support comes with all distributions

Besides that, you will need:

VisIt version 3.1.X or 3.2.X installed on your laptop (3.3.X is NOT supported yet). It will act as a client. You may get the free binary from here.
A VNC client or similar means to access LRZ Remote Visualisation Service. Instruction can be found here.
You are encouraged to bring data you from your own research and projects, although we cannot guarantee compatibility for any specific format.
If you cannot, alternative datasets will be provided.
