Many academic users would like to have Gurobi installed on multiple computers, such as a university machine, a home computer, and a laptop.
In this situation, you should create additional individual academic licenses for your other computers:
To install a free academic license yourself, connect your computer to the university network, then follow the instructions for a named-user academic license here.
You can repeat this process to activate additional licenses for additional computers.
However, if you wish to run Gurobi on a cluster of computers or in a computer lab, a better option is to request an academic site license.
