NOTE: There are some changes to this document for Grid 2.5. Please see below and in-context. Please contact RCS with any questions.
If you wish to use applications on the Grid via a graphical user interface (GUI), we support remote desktop sessions to the Grid using the NoMachine NX client software. Like Windows RDP or VNC running Stata on the Grid 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://researchnx.hbs.edu:4443 (Grid 2.5: https://researchnx-new.hbs.edu:4443/nxwebplayer). However, we've found connection speeds for the web-based interface to be significantly slower. For more information, please scroll down to the section Web Client Usage.
Local Client Installation
After the desktop installation is complete, please restart your machine before proceeding.
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 researchnx.hbs.edu (Grid 2.5: researchnx-new.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."
On the recent connections screen, click "Preferences."
Next click "Appearances," check the option "Don't show other computers on the network," and click "Done."
Highlight the "researchnx.hbs.edu" (Grid 2.5: researchnx-new.hbs.edu) connection 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, and 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. 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.
Congrats. You are now on one of two login nodes that are the gateway to the Grid.
To access software on the grid, click "Applications" and select your software.
Web Client Usage
NoMachine offers a web client that may be accessed at https://researchnx.hbs.edu:4443 (Grid 2.5: https://researchnx-new.hbs.edu:4443/nxwebplayer). As with the local client, you will enter your HBS username (without @hbs.edu) and password. Once your HBS credentials are accepted, you will be sent to the welcome page, where you will click on the computer icon (see screenshot below) to create a new session.
You will subsequently be brought to a virtual desktop, from which you can access Stata or any other tools, as shown below.
To log out, you cannot simply close your browser as this will not end your session. You must go to the System tab and then select Log out (see screenshot below).
