VCL is short for "Virtual Computing Lab." Duke University has set up several virtual computing lab images and they can be used to work remotely.

VCL and MATLAB
Using MATLAB over a wireless connection with port forwarding for X11 works great, right up until you need to hear the sounds MATLAB is making. In order to run a version of MATLAB that will also send sounds to your speaker, you will need to use a VCL that runs Windows in a window.
Using a Windows VCL and MATLAB
There are several steps to using a Windows VCL with the MATLAB distribution. The end result will be having a window open on your local computer in which a Windows 10 distribution is running. The process is slightly more complicated than the Working from home steps there are some similarities. Duke has posted instructions at their Knowledge Database site for "How to create a new VCM reservation." This includes listing the required software for opening a VCM as well as how to make a reservation. There is a virtual machine that has MATLAB installed *however* it is MATLAB 2016. It is probably better to start a blank Windows 10 distribution and then install MATLAB yourself.
Process Summary
Here is a summary of the process:
- Go to https://vcm.duke.edu/; enter your Duke ID and password if requested
- Click the "Reserve a VM" tab at the top
- Pick the "Plain VM No Apps Windows 10" from the pull down box and create the reservation
- You will go to a page called "VM Management Tools"
- Wait until you get an email from OIT indicating that you have a VM ready. If the "VM Status" is "reserving," you will not be able to run your VM.
- Click the "Remote Desktop" link. Depending on your operating system, this should download a link that you can open to run your virtual machine.
Installing MATLAB
Accessing CIFS from MATLAB in Windows VCL
Your CIFS space - which is to say, ~ in your UNIX account - is mounted as drive Z:. If you run the MATLAB program on that Windows distribution:
Start -> All Programs -> Mathematics & Statistics -> MATLAB -> VERSION -> MATLAB VERSION
(where VERSION is something like R2020a)
you can switch into your CIFS space by typing "cd Z:" in MATLAB's command window. You can use the UNIX cd and ls commands in the MATLAB command window to move around.
Using a Linux VCL and MATLAB
There are several steps to using a VCL with the MATLAB distribution. The process is slightly more complicated than the Working from home steps but they are similar. They are summarized here (for Windows, Mac, and Linux users) and the latter four steps from the list are discussed in detail below.
- Install the appropriate software if need be. For Windows users, this means MobaXterm; for Mac users, this means XQuartz; for Linux users - you're probably all good already...
- Make a reservation at https://vcl.oit.duke.edu/
- Receive reservation confirmation, including the IP address of your virtual machine
- Connect to the virtual machine using
ssh -XY netid@machineid
- where machineid is the four-part IP address of the virtual machine you were given.
- Profit
Making a Reservation / Receiving Confirmation
- To make a reservation, point your browser to https://vcm.duke.edu/, log in using your Duke credentials, and then select New Reservation
- Choose the "OIT Linux Lab 2013" environment, Now, and a duration of 4 hours (or whatever is longest)
- Click "Create Reservation"
Receiving Confirmation
In a few seconds, possibly minutes, you should receive an e-mail with your reservation confirmation and an IP address. After that happens, within 20 seconds, the web page should refresh and there will be a "Connect!" button on the web page. Click that button.
Connecting to the Virtual Machine
ssh -XY netid@machineid
- You should now come to the command prompt for the virtual machine over which you have been given temporary dominion. Note that these virtual machines access your OIT space just like logging in to Teer machines would.
Profit
And by profit, I mean you can now run UNIX commands just like the good old days. Like
matlab &
will bring up MATLAB and typing
surfc(rand(20))
will work. These machines should mount your CIFS drive.
Questions
Post your questions by editing the discussion page of this article. Edit the page, then scroll to the bottom and add a question by putting in the characters *{{Q}}, followed by your question and finally your signature (with four tildes, i.e. ~~~~). Using the {{Q}} will automatically put the page in the category of pages with questions - other editors hoping to help out can then go to that category page to see where the questions are. See the page for Template:Q for details and examples.
