How do I access the HPC Cluster?

You can remotely access the frontend machines astro01-09 via SSH to submit jobs or to analyze data (see Hardware for an up to date list of available frontends). For example, you can login to the astro06 machine entering the following in the command line

ssh username@astro06.hpc.ku.dk

From which you will be prompted to enter your password (Note: If the connection times out, it's likely that your IP address is not recognised). By entering the correct password, you will arrive at your home directory /groups/astro/username. It may be a good idea to check the load factor after logging in, using "top", and choose a different frontend if the CPU or memory use is already high (use "<" or ">" in top to temporarily change from sorting on CPU to memory / virtual memory).
