Run Materials Studio on a HPC

I want to run MS jobs on university HPC rather than on my 12-core workstation. I am trying to learn from previous posts on our BIOVIA MS community but still confused. It would be great if SO can help answer these questions:

Q1. What is the link/difference between running a MS job on HPC and the GATEWAY?

Q2. Do I need to have a new license file for running a job on HPC? If so, what happen to the installed MS on my current destop?

Q3. Is there any tutorial regarding submitting a MS job on HPC?
