Gurobi: Difference between revisions

Note that all Gurobi license checkouts are handled by a single license server located in Ontario, so that it is important for you to assure that your use of Gurobi limits as much as possible license checkout attempts. Rather than checking out a license for each invocation of Gurobi in a job - which may occur dozens or even hundreds of times - you should ensure that your program, whatever the language or environment used, only makes a single license checkout and then reuses this license token throughout the lifetime of the job. This will improve your job's performance since contacting a remote license server is very costly in time and also improve the responsiveness of our license server for everyone who is using Gurobi. Some documentation on this subject for C++ programs may be found [https://www.gurobi.com/documentation/9.5/refman/cpp_env2.html here], explaining how to create a single Gurobi environment which can then be used for all your models. Python users can consult this [https://www.gurobi.com/documentation/9.5/refman/py_env_start.html page], which discusses how to implement the same idea of using a single environment and thus a single license token with multiple models.
