Account management at the VSC is mostly done through the web site using your institute account rather than your VSC account.

Managing user credentials

  • You use the VSC account page to request your account as explained on the "Account request" pages. You'll also need to create an SSH-key which is also explained on those pages.
  • Once your account is active and you can log on to your home cluster, you can use the account management pages for many other operations:
    • If you want to access the VSC clusters from more than one computer, it is good practice to use a different key for each computer. You can upload additional keys via the account management page. In that way, if your computer is stolen, all you need to do is remove the key for that computer and your account is safe again.
    • If you've messed up your keys, you can restore the keys on the cluster or upload a new key and then delete the old one.

Group and Virtual Organisation management

Once your VSC account is active and you can log on to your home cluster, you can also manage groups through the account management web interface. Groups (a Linux/UNIX concept) are used to control access to licensed software (e.g., software licenses paid for by one or more research groups), to create subdirectories where researchers working on the same project can collaborate and control access to those files, and to control access to project credits on clusters that use these (all clusters at KU Leuven).

Managing disk space

The amount of disk space that a user can use on the various file systems on the system is limited by quota on the amount of disk space and number of files. UGent users can see and request upgrades for their quota on the Account management site (Users need to be in a VO (Virtual Organisation) to request aditional quota. Creating and joining a VO is also done trought the Account Management website). On other sites checking your disk space use is still mostly done from the command line and requesting more quote is done via email.
