Users

Creation of a new user

Only people with a Linux user account on Mufasa can access the machine and interact with it.

Only Linux users registered to SLURM's accounting system can use SLURM to run jobs.

To request the creation of a new Linux user and its registration to SLURM's accounting system, a person must write an email to Giulio Fontana.

The request needs to specify what follows:

1. name and surname of the person that the Linux user is associated to
2. email of the person
3. user category, which can be either student (for M.Sc. students) or a researcher (for everyone else, including Ph.D. students)
4. what research group the person belongs to, among those listed in Group names (see below)
5. (in CC to the email) the academic staff in charge of Mufasa who authorized the request

User and groups on Mufasa

This section explains user and group policy on Mufasa, and the procedure to create new users and associate them to groups.

Usernames

Mufasa usernames have the form xyyy (all lowercase), where x is the first letter of the first name of the person, and yyy is their complete surname. For instance, a person called Mario Rossi will be assigned username mrossi.

If multiple users with the same surname and first letter of the first name exist, those created after the very first one are given usernames including a two-digit counter: mrossi, mrossi01, mrossi02 and so on.

Group names

On Linux machines such as Mufasa, users belong to groups. On Mufasa, groups are used to identify the research group that a specific user is part of. Assigment of Mufasa's users to groups follow these rules:

• All users corresponding to physical people belong to group users
• Additionally, each user must belong to one and only one of the following groups:
  • cartcas, i.e. CartCasLab (prof. Cerveri);
  • biomech, i.e. Biomechanics Research Group (prof. Votta);
  • nearmrs, i.e. Medical Robotics Section of NearLab (prof. De Momi);
  • nearnes, i.e. NeuroEngineering Section of NearLab (prof. Ferrante);
  • bio, for BioEngineering users not belonging to any of the research groups listed above.

The person cited within brackets is the faculty who is in charge of Mufasa for each group.
