Access to Niagara is not enabled automatically for everyone with a Compute Canada account, but anyone with an active Compute Canada account can get their access enabled.
Access to Niagara is not enabled automatically for everyone with an Alliance account, but anyone with an active Alliance account can get their access enabled.
   
   
If you have an active Compute Canada account but you do not have access to Niagara yet (e.g. because you are a new user and belong to a group whose primary PI does not have an allocation as granted in the annual [https://www.computecanada.ca/research-portal/accessing-resources/resource-allocation-competitions Compute Canada RAC]), go to the [https://ccdb.computecanada.ca/services/opt_in opt-in page on the CCDB site].  After clicking the "Join" button on that page, it usually takes only one or two business days for access to be granted.
