Scientific Computing I / Wissenschaftliches Rechnen I

The lecture will show the pratical implementation of standard numerical algorithmns. We focus on the special properties of the floating-point arithmetics and difficulties when formulating the algorithms in a high-level programming language, such as C. Utilities for searching fo errors and post proccessing of results will be explained, too. Additionally, existing software packages that are highly recommended for use in own implementations will be introduced.

Teaching Material

Virtual Machine

In order to provide all students an equivalent environment for handling the exercises, we created a virtual machine with a small Ubuntu 20.04 setup including the necessary tool and libraries. The virtual machine is configured to be used in Virtual Box, but it can also be imported in other virtualization tools like VMware or Parallels.

Since the virtual machine contains a 64 bit operating system a 64 bit host CPU with enabled virtualization. The virtualization, mostly called Intel VT or AMD-V, can be enabled in the BIOS settings if not enabled by default. Normally, all 64 bit CPUs from the last 8 years support it.

The virtual machine is configured to use Virtual Box's way to connect to the outside world via network. Furthermore we included a port forwarding to the SSH server running inside the virtual machine. After starting the virtual machine you can connect to it from the terminal of your Linux or Mac computer via:

  ssh -p 22022 scuser@localhost

If using Windows as main operating system you have to install an SSH client first. A common tool is Putty. Newer versions of WIndows 10 (since end of 2018) already ship an SSH client on the command line. It can be used like above.

The default username for the virtual machine is scuser with the passwort scuser.
