Accessing the test cluster
The test cluster holds several submission nodes, a central manager and worker nodes. You will have received a username, password and a host name in the course which you can use for logging in via SSH.
On Linux and MacOS X, an OpenSSH client is usually installed by default.
In case you want X11 graphics (not required by the course), you need XQuartz on the Mac and use ssh -X.
In the course, it will also be necessary to copy files to your machine to look at them (pictures, videos). For this, you can use scp or rsync.
Windows
On Windows, you can either use PUTTY, install a Linux distribution using the Windows Subsystem for Linux (WSL) via the Store, or use Cygwin.
If you want X11 graphics (not required by the course), you may use Xming for example in combination with WSL or Cygwin. To make use of it, you may have to run:
export DISPLAY=localhost:0.0in the terminal once before running ssh -X.
In the course, it will also be necessary to copy files to your machine to look at them (pictures, videos). For this, you can use scp or rsync
inside WSL or Cygwin, or use a graphical tool like WinSCP natively on Windows.
Preparing your environment
Several of the files mentioned in the course can be created manually (by copy-pasting from the page), but it is usually more easy to check out the repository.
You can do so by running:
git clone https://github.com/olifre/gridka-school-2019-htcondor.gitThe repository will then be available in the directory gridka-school-2019-htcondor.
