Using the Gurobi Optimizer Solvers on the Eagle System
Gurobi Optimizer is a suite of solvers for mathematical programming.
For documentation, forums, and FAQs, see the Gurobi website.
Gurobi includes a linear programming solver (LP), quadratic programming solver (QP), quadratically constrained programming solver (QCP), mixed-integer linear programming solver (MILP), mixed-integer quadratic programming solver (MIQP), and a mixed-integer quadratically constrained programming solver (MIQCP).
Eagle hosts 6 general use (including commercial) and 18 academic/government Gurobi licenses. The Gurobi interactive shell will run by typing "gurobi.sh". Gurobi can also be interfaced with C/C++/Java/MATLAB/R codes by linking with the Gurobi libraries.
For details on Gurobi programming, see the Gurobi website.
Gurobi and MATLAB
To use the Gurobi solver with MATLAB, make sure you have the Gurobi and MATLAB environment modules loaded, then issue the following two commands from the MATLAB prompt or your script:
>> grb = getenv('GRB_MATLAB_PATH')
Gurobi and General Algebraic Modeling System
The General Algebraic Modeling System (GAMS) is a high-level modeling system for mathematical programming and optimization. The GAMS package installed at NREL includes Gurobi solvers. For more information, see using GAMS on Eagle.
Note that the Gurobi license for this interface is separate from the standalone Gurobi license, and supports far more instances.
Important: When using the Gurobi solver in GAMS, the user should NOT load the Gurobi module. Simply using "module load gams" will be enough to load the required Gurobi components and access rights.
