More information about getting access (eligibility and assessment criteria) for HPC users is available here: https://prace-ri.eu/hpc-access/eurohpc-access/.
Procedure for accessing HPC Vega after accepted proposal
After the proposal is technically reviewed and accepted, the applicant will receive a confirmation message from email@example.com with a request to send fulfilled EuroHPC User Data Protection Agreement form and also send his SSH public key to log in to the system. Our support team will then copy applicant's SSH public key to the "SSO identity management server". No access to this server is granted to EuroHPC applicants. If applicant wants to change his own SSH public key, a new public key needs to be sent to firstname.lastname@example.org.
