To get access you will need a username and Initial password that will be sent to you.
Quickstart for Niagara and Mist documentation page can be found here:
$ ssh -Y lclmaoroph@niagara.scinet.utoronto.ca Warning: Permanently added 'niagara.scinet.utoronto.ca' (RSA) to the list of known hosts. Password: =============================================================================== SciNet welcomes you to the NIAGARA supercomputer. This is a Niagara login node. Use this node to develop and compile code, to run short tests, and to submit computations to the scheduler. Remember that /scratch is never backed-up. Documentation: https://docs.scinet.utoronto.ca/index.php/Niagara_Quickstart Support: support@scinet.utoronto.ca or niagara@computecanada.ca =============================================================================== lclmaoroph@nia-login06:~$
Once you get access, you should change your password using this command on Niagara login node:
ldappasswd -H ldaps://ldapk9.scinet.utoronto.ca -D "uid=lclmaoroph,ou=People,dc=computecanada,dc=ca" -W -S
After that you MUST set up your SSH keys for login to Niagara
(https://docs.scinet.utoronto.ca/index.php/SSH_keys) and also enable Two-Factor authentication (https://docs.scinet.utoronto.ca/index.php/Two-Factor_setup).
Scratch area is available under $SCRATCH
cd $SCRATCH $ pwd /scratch/i/iscscc-scinet/lclmaoroph
Compute resource
Use slurm to allocate and run jobs on the compute partition.
The cluster has Intel Skylake CPUs and InfiniBand EDR networking:
