GUROBI

GUROBI  is a soon to be fully released solver that provides state-of-the-art simplex-based linear programming (LP) and mixed-integer programming (MIP) capability.  The GUROBI MIP solver includes shared memory parallelism, capable of simultaneously exploiting any number of processors and cores per processor. The implementation is deterministic: two separate runs on the same model will produce identical solution paths. The Gurobi solver is available for the 32-bit and 64-bit versions of Windows and Linux.  Details on GYROBI can be found at http://www.gurobi.com/ .

A bare bones, free version of GUROBI is available as COINGUROBI.
