  This doesn't appear to be related to Gurobi - that output comes from the NumExpr library. I would try following the suggestion and set the \(\texttt{NUMEXPR_NUM_THREADS}\) environment variable to 16. This can be done by following the instructions in NumExpr's Threadpool Configuration documentation.
