Creation of a new user of Mufasa
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.
All requests for the creation of new users and their registration to SLURM's accounting must be authorized by a member of the academic staff in charge of Mufasa.
Requests are done by writing an email
- TO: Giulio Fontana
- CC: the person who authorizes the request
The email must provide the following 5 pieces of information:
- name and surname of the person that the new Linux user is associated to
- (POLIMI) email address of the person
- user category, which can be either student (for M.Sc. students) or researcher (for everyone else, including Ph.D. students)
- research group that the person belongs to, among those listed in Group names below
- who authorizes the request
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 surname (or part of it if it's too long: maximum length for usernames is 9 characters). For instance, a person called Giuseppe Brambilla will be assigned username gbrambill.
Removal of old users
To preserve Mufasa's safety, old users must be removed (e.g., those of M.Sc. students who graduated). Removing a user means doing two things:
- deleting the user from the Linux system
- destroying the user's home directory
Whenever a person ceases to have reason to use Mufasa, the people responsible for them (Ph.D., professors, ...) are required to:
- copy anything useful still contained in the person's home directory somewhere else
- write an email to Giulio Fontana to ask for the removal of the user
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.
