On-HBS-Campus
TEST TEST
To connect to the HBSGrid from on-campus, you must be connected to the HBS Network via either a wired ethernet connection or the HBS Secure Wireless Network.
Off-HBS-Campus
From off-HBS-campus, the HBSGrid can only be accessed through a virtual private network (VPN) connection using the Pulse Secure software. A VPN ensures that all communication between your computer and grid resources are encrypted. Harvard University also mandates that all persons accessing sensitive systems use two-factor authentication as a part of their login process.
Pulse Secure VPN Software Installation and Set-UpPersons with HBS-issued desktops and laptops may already have the necessary software. If you need to re-download, re-install, or download a new version of the software (e.g., VPN with two-factor), it can be found here.
Collaborators and guest users can download the VPN Pulse Secure software (with two-factor) here for PC or Mac.
Please ensure that the VPN software Pulse Secure has been installed as described in the previous step, and that the Duo Mobile app (or some other two-factor authentication method), also described above, has been installed and registered/configured.
For connecting to the HBS campus network, please follow the appropriate section on the VPN/DUO Quick Reference Guide. For example, to connect to the VPN with Duo Mobile 'push' using the smartphone mobile application, please see Section 3, steps 1 and 5 through 8.
- GUI Login to the HBSGrid

If you wish to use applications on the HBSGrid via a graphical user interface (GUI), we support remote desktop sessions using the NoMachine NX client software. Like Windows RDP or VNC running Stata on the cluster looks like running Stata on your desktop, for example. An additional application to run X11 (a long-established Unix graphics windows system) such as Xming or XQuartz is not needed. With NoMachine, Unix/Linux knowledge is not required.
Note: NoMachine also has a browser-based interface which you can connect to at: https://hbsgrid-nx.hbs.edu:4443/nxwebplayer. However, we've found connection speeds of the installed softwareto be significantly faster.
- Local Client Connection

On the Welcome page, click on “Create a new connection” and click "Continue."
On the "New connect" screen use the default Protocol setting "NX" and click "Continue." Next, enter host information for the compute grid, hbsgrid-nx.hbs.edu, on port 4000. Ensure the checkbox for UDP communication is checked and click "Continue."
On the next screen choose "Password" selected and click "Continue." Next, please check "Don't use a proxy" check and click "Continue." Select the checkbox for "Create a link on the desktop," and click "Continue."
Next click "Settings" in the top right corner, click "Privacy", and check the option "Don't show other computers on the network," and click "Done."
Highlight the hbsgrid-nx.hbs.educonnection and click "Connect."
In the window "Verify host authenticity", click "Yes." Next enter your username and password. For security purposes, do not select "Save this password."
After a few moments, a window will appear for windowing options. Click "New virtual desktop or custom session," click "Create a new GNOME virtual desktop” and click "Continue."
On the next few pages leave the default setting and check "Don't show this message again."
The virtual desktop then appears. Congrats. You are now on one of two login nodes that are the gateway to the Grid!
- Configure Your Desktop
-
If you find that your desktop is the wrong size (e.g., is larger than the window containing it) you can adjust it via the NoMachine settings page. When you hover over the upper right corner of the screen a page peel-back icon appears. Click on the image of the peel-back.
Next click on "Display" and "Resize remote screen" and click "Done" twice. For more details about configuring your display you may refer to the NoMachine documentation.
The Grid runs the Gnome desktop and includes "Tweak Tool", a configuration utility for customizing your desktop. For example, to add icons back to your NoMachine desktop, launch Tweak Tool
and click on the Desktop left tab (1) and turn on the Icons on Desktop option (2):
More information about configuring NoMachine and the Gnome desktop are available in our NoMachine Interface Changes guide.
