Callbacks
As you might imagine, since the actual optimization task runs on a
remote system in a Compute Server environment, Gurobi callbacks give
different behavior than they do when the task runs locally. In
particular, callbacks are both less frequent and more restrictive.
You will only receive MESSAGE, BARRIER,
SIMPLEX, MIP, and MIPSOL callbacks; you will not
receive PRESOLVE or MIPNODE callbacks. As a result,
you will only have access to a subset of the callback information that
you would be able to obtain when running locally. You can still
request that the optimization be terminated from any of the callbacks
you receive. Please refer to the Callback
Code section for more information on the
various callback codes.
