There are two licensing options for MATLAB Parallel Server, Online Licensing and Local Licensing.
The first option is Online Licensing. Online Licensing allows you to use a cluster in the Cloud on MathWorks Cloud Center or setup your own dedicated cluster locally. Your cluster will reach back to the MathWorks Servers to verify it's license. The first step is to have your administrator add you to the license, once done you can use the MathWorks Cloud Center to setup your cluster.
After you are listed on the MATLAB Parallel Server license, the link below will guide you through using the Cloud Center, setting up an Amazon account, and the other needed steps.

If you are not trying to setup a cluster in the cloud and instead are trying to run it on your personal cluster hardware with Online Licensing then please see the link below:

The second option is for large scale clusters that cannot connect to the internet. These are usually data centers and HPC clusters already setup by the University. In order to access this type of cluster, please contact your University to see what they have available.
If you are an administrator and want to setup a large scale HPC cluster, then please see the link below for those instructions:
