RCS maintains and operates various systems and clusters which can be connected to from within the University of Calgary campus network or via the University of Calgary IT General VPN.
Service Overview
RCS operates the following clusters and services. Most services can only be accessed from the campus network or through the IT General VPN.
| Cluster | Service | Hostname | Access | Accessible by |
|---|---|---|---|---|
| ARC | Login Node | arc.ucalgary.ca | SSH via VPN/Campus | All ARC users |
| JupyterHub | https://jupyter.ucalgary.ca/ | HTTPS via VPN | ||
| Open OnDemand | https://ood-arc.rcs.ucalgary.ca/ | HTTPS | ||
| Data Transfer Node | arc-dtn.ucalgary.ca | SSH via VPN | ||
| TALC | Login Node | talc.ucalgary.ca | SSH | All TALC users |
| JupyterHub | https://talc.ucalgary.ca/ | HTTPS via VPN | ||
| MARC | Login Node | marc.ucalgary.ca | SSH via Citrix | MARC users |
Connecting to the University IT General VPN
Connections to certain services must be accessed from the University of Calgary campus network or via the University of Calgary IT General VPN. You may only connect to one of our login nodes via SSH or the Citrix service from either the campus network or after you have connected to the IT General VPN.
Connecting using FortiClient VPN
You may install the FortiClient VPN program to connect your computer to the IT General VPN.
Refer to the following pages based on your operating system:
| Operating System | Documentation |
|---|---|
| Windows | https://ucalgary.service-now.com/kb_view.do?sysparm_article=KB0033671 |
| MacOS | https://ucalgary.service-now.com/kb_view.do?sysparm_article=KB0033673 |
| Linux | https://ucalgary.service-now.com/kb_view.do?sysparm_article=KB0030086 |
For assistance with connecting to the IT General VPN, please contact the University IT team through UService.
Once you are connected to the VPN, you may access any web services with your web browser or connect to login nodes via SSH using a SSH client of your choice.
Connecting using Fortinet Web Portal
The Fortinet web portal allows VPN access through your web browser. This option is available for users that prefer not to use the FortiClient program or cannot install the FortiClient VPN program.
| VPN | Notes | URL |
|---|---|---|
| IT General VPN | To log-in, click on 'Single Sign-On'. | https://generalconnect.ucalgary.ca:10443/remote/login |
Once connected, you may use the 'Quick Connection' option to connect to a website or SSH to a login node.
Connecting to a web site
- Click 'Quick Connection'
- Click HTTP/HTTPS
- Enter the URL that you want to go to i.e. jupyter.ucalgary.ca or talc.ucalgary.ca
- The website will open in a new browser tab and you may proceed normally.
Connecting via SSH
- Click 'Quick Connection'
- Click SSH
- Fill out the "Host" box with
username@hostname. For example,uofcusername@arc.ucalgary.ca - A new browser tab will open with a prompt for your UC username/password
- The ssh terminal will open in a new tab and you can proceed typing commands into the terminal normally.
Connecting with SSH
Secure Shell (SSH) is an encrypted network protocol that allows secure communication between your computer and a server.
On Linux or MacOS computers, SSH is most likely installed and can be used by opening a terminal and running:
ssh username@arc.ucalgary.ca
For work requiring X11 forwarding, pass in the -X flag.
ssh -X username@arc.ucalgary.ca
On Windows, there are various clients that can be used to connect to our cluster including:
- PuTTY
- MobaXterm
External Collaborators
The main requirement for a researcher to have an account on ARC, or any other compute cluster at UofC is that the researcher must have a UofC IT account and have a corresponding UofC e-mail address. This is because access to the clusters is controlled by the central authentication system as to the rest of the electronic services on campus. Thus, external collaborators cannot get an account on ARC unless they have a UofC IT account.
To address this issue and to facilitate a collaborative environment there is
a hiring template for External Research Collaborators who need to remotely access the secure compute and
High Performance Compute (HPC) resources at the University of Calgary.
This new designation allows you to request General Associate (GA) access for external research collaborators,
that are not University of Calgary employees or associated with AHS, to our HPC and Secure Compute services in an expedited manner.
Researchers in this category require a Principal Investigator (PI) or a PI delegate to submit a Template Based Hire (TBH)
with the new GA template.
Please note that AHS external researchers have their own GA template available for them and they don’t need to use this new GA template.
Principal Investigators or their delegates can request the creation of a new General Associate External Collaborator
following the Template Base Hire form process in PeopleSoft and selecting the template
“UC_CWR_EXT_RES_CL – Gen Associate – External Research Collaborator”.
These requests will need to be approved by Research Computing Services, who is managing HPC.
Once the transaction is approved, it will go to HR to complete the hiring process and the new account will be ready for your associate.
Actions Required
- For new External Research Collaborators, please follow the Template Base Hire described above.
- If you currently have External Collaborators under a different template but fits into the new category, please let us know their names and email addresses and we will transfer them to the proper template.
