Accessing the Chimera Cluster
Most of the cluster services are accessible using your existing SIS login/password.
ssh sis_login_name@hpc.troja.mff.cuni.cz
Other services:
- gitlab account at https://gitlab.mff.cuni.cz
(Note: Karlin local gitlab is separate service https://gitlab.karlin.mff.cuni.cz) - Initialize your JupyterHub Chimera account by loging at https://hpc.troja.mff.cuni.cz:8000
- Mattermost (collaboration platform designed for technical and operational teams).
This is useful to get notifications from admins about planned outages and report
possible issues with Chimera and/or JupyterHub.
