Virtual Computer Lab (VCL)

The Engineering Virtual Computer Lab (VCL) provides a way to run a variety of software provided by UMD on powerful servers and display the running software on your computer locally.

Note: The VPN is now required to access the VCL from Off Campus
For more information, please visit this ask article.

The maintenance window for the VCL is Tuesday mornings from 5-7 am.  Expect disruptions and outages during this time frame as we do our best to keep our technology up to date. 

The VCL leverages software provided by Citrix to perform its tasks, so that the required resources are handled by our servers and not your computer. This allows more widespread access to resource-intensive programs on a wider variety of computer hardware than would otherwise be possible.

Getting Started

We recommend updating your installation of Workspace App before every semester for the latest performance enhancements, security updates and bug fixes. If you are still running Citrix Receiver (replaced by Workspace App), please upgrade now!

Download and install the Citrix client for your platform:

  • Windows - Choose the Download button for "Citrix Workspace App".
    When prompted, enter as the web server and at the login dialog enter your UM directory ID username and UM directory password.

Citrix Workspace enter server information     Enter UMD Directory ID and password to login

Once you set up Workspace App, you can access VCL applications from the Workspace App, or directly from the website,

Recent versions of Citrix Workspace for Windows match display resolution and DPI scale settings of the local Windows client to the Citrix session. To make text larger, we suggest setting “Scale and layout” to 100% in the Settings on your Windows computer.

We have made some desktops available for remote connection, you may access them here You still need to have the Citrix Workspace App installed. When finished, please click the Ctrl+Alt+Del button at the top and sign out.


After installing the client, for applications go to Login page and enter your Directory ID username and your directory password.

Run Application

After logging in, click on an application to run the program. When prompted, choose "Permit all access" to allow the VCL to access your machine for opening and saving files. Check the "Do not ask me again for this site" box to not be asked every time you use the VCL from your computer.

Permit all access to allow Citrix Workspace to function properly


VCL Software List


Saving Files to Your Personal Computer

  • Save in \\Client\C$(location will vary depending on the application you’re using). You cannot save to the C: drive on the VCL application host servers. On Windows, \\Client\C$ is the root directory of your client computer. On a Mac, \\Client\C$ is your Mac Home folder. In some applications, we map a V: to \\Client\C$ since they do not handle the UNC mapping well. You may also be able to save to a USB, if your USB is the E: drive, then \\Client\E$

Saving files to your personal computer

  • The Documents folder on the VCL is redirected to your personal space on our files server, the U drive


Saving Files to VCL Server User Folder (U)

An option to save to a user folder on a VCL server share. Your folder will be mapped as the (U:) drive.

  • 2 GB storage per user, saved files available to you in future sessions (automatic increases up to 10GB in 2 GB increments, updated daily based on usage)
  • Available via Secure FTP, such as WinSCP on Windows or Fetch on a Mac, hostname: Use SFTP setting or specify port 22
  • May have better performance with applications that use a lot of disk I/O
  • Alternative if you are having an issue saving locally, or some applications which have issues saving locally such as Cadence

Saving files on the server

Downloading files using Winscp  Watch our video on saving to your server folder (U:) and using WinSCP to download files from that location. 


Saving Files to TERPDrives/Kumo Cloud Storage

This is an active service, and no longer a limited pilot. If you participated in the pilot, you do need to authorize any cloud services again.

This service will map a Windows drive in your VCL or computer lab session to any cloud storage spaces you authorize (*Box, GoogleDrive, DropBox, OneDrive). You control what cloud storage services to connect to, if any. To do so, go to and authorize which cloud services you would like to use when using the VCL and computer labs. Then, when launching applications in the VCL, those drives will be mapped as in the image below.

Saving files using TerpDrive/Kumo

Thanks to DivIT for offering this service.

*To activate your free UMD Box account, up to 50GB of storage, information is here, UMD Box Service


Saving File to USB, External Hard Drives, and Your iPad

On many applications, you will be able to save to other drives on your client machine, such as a USB device or additional hard drive.

Saving to your iPad

To save files onto your iPad, you will need to turn on Shared Documents.

  • From the iPad Citrix Workspace App click the Gear icon in the upper right, choose Advanced, and then turn on Shared Documents.

Saving files to your iPad

  • Relaunch your session
  • Save locally via the \\Client\C$(V:) just as you would do from a typical VCL session from a PC or Mac.

Note: Files saved from the VCL are not accessible from other iPad apps.


Logging Out


In most cases, exiting an application will close your session; however, closing some applications (such as Creo Parametric and Cadence) doesn’t always fully end your session properly. If you are having trouble running an application you recently closed, your session may not have fully terminated.

To fully end your session:

  • Right-click on the Citrix icon in the icon tray in lower right-hand corner of the screen.
  • Select Online Sessions.
  • Choose Connection Center.

Choose Citrix Connection Center

  • Highlight the server, then Log Off.

Highlight the server and logoff


  • Right click on the Citrix Viewer icon in the Dock and choose Quit.

Right click on the Citrix Viewer on the Mac to quit

  • Choose Log Off.

Choose Logoff
