BENCH

BENCH is not really a solver but rather a procedure for running the same model across all requested solvers for a model type that are available to the user.  Namely it is a procedure that facilitates benchmarking of GAMS optimization solvers.  When invoked BENCH calls all requested GAMS solvers for a particular model type and captures results in the standard GAMS listing file format.  Solvers to be benchmarked are specified through the solver options file.  BENCH can also call the EXAMINER solver and interact with the PAVER performance analysis server.  BENCH is distributed free with any GAMS system.  BENCH can only run solvers for which the user has a valid license.  The GAMS solver manual for BENCH is bench.pdf.
