Ready to get started? Follow the menu items on the left to learn how to install, configure and use HMDC's Research Computing Environment, powered by NoMachine NX4 and HTCondor.
An exciting feature of the RCE environment, is the ability to access your desktop and your jobs through your web browser.
Accessing the RCE via HTTP
Open your preferred web browser and navigate to https://rce.hmdc.harvard.edu. Enter your username and password, and click OK. | |
If you have an already running session, highlight your session and click Connect. Otherwise, start a new session. The web interface completely mirrors the NoMachine client interface. | |
Why use the NoMachine Desktop Client at all?
You may find yourself using the Web client interface to access your RCE session, rather than the NoMachine Desktop client. Great! However, if you need to print documents or connect a USB storage device to your RCE session, you must use the NoMachine NX4 Desktop client. If you never need to print or access USB storage from RCE, ditch the NoMachine NX4 Desktop client and enjoy the HMDC supported NoMachine NX4 Web client interface!
Download the NoMachine client for your OS: Please download the NoMachine client from HMDC; it provides a superior RCE experience. Our support staff will ask you to download and install our version if you encounter difficulties using the RCE. Windows zipfile |

Do you need to print from applications in the RCE? NoMachine NX4 allows you to attach any printer to a currently running RCE desktop. Printing from the RCE with NX4 is as simple as printing on your local desktop. Just click Print. First, you need to attach a printer to your RCE Desktop in the NoMachine NX4 client. Please note that printer sharing only works from the NoMachine NX4 desktop client, not the mobile client or the web client.
Setting Up Printer Sharing in Mac OS X |
|
Click the Apple logo in the upper left hand corner of your screen and select System Preferences |
|
Click the Sharing button | |
Click the lock on the bottom left of the window to unlock your sharing preferences and enter your administrative password. You should see a number of printers listed with unchecked checkboxes. If you see no printers listed, you haven't configured any printers. Please add a printer, first. If you don't know how to add a printer, mail support@help.hmdc.harvard.edu. |
|
Click the On checkbox for Printer Sharing on the left side of the window. Then, click the checkboxes for each printer you want to use inside the RCE Desktop environment as shown. |
|
For each printer you want to share, click the + button, highlight yourself, and click Select. | |
You should now see that Printer Sharing is checked On, the printers you wish to share with your RCE desktop are also checked, and that your username Can Print while 'Everyone' has no access. | |
Setting Up Printer Sharing in Windows |
|
Click the Start button and select Control Panel. Then, click View devices and printers.
|
|
Double-click on the printer you want to share with RCE6.
|

Connecting a printer to your RCE Desktop |
|
Once completed, click the Lock and exit the screen by clicking the X button on the upper left hand corner of the screen. Open your RCE6 session by clicking on the RCE6 icon on your desktop which you set up earlier. | |
On the top right-side of your RCE desktop, click the !M button and select Show the menu panel. | |
Click Devices | |
Click Connect a printer. |
|
Select the printer you wish to connect. Click Done. | |
Make sure to select the Private radio button, otherwise all NX4 users will be able to print directly to your device. If you're going to use this printer for every RCE session, you may check Make this the default printer and Export this printer at session startup. Then, click Connect. |
|
If you see a checkmark next to your printer icon and a green indicator, you're done. Your printer is connected. Continue to click Done until you return to your desktop. | |
Open a document or a web browser and attempt to print. When selecting Print from an RCE launched browser like Google Chrome, you should see your printer in the list. | |
To suspend your session close the browser tab, or browser window. In the case of the desktop client you can simply close the window. You can also Go to the Nomachine Menu Panel and click the disconnect icon in the bottom right of the page.
