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). 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).

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 be arrive at your home directory
