Abstract. Optimization problems where the evaluation step is com-
putationally intensive are becoming increasingly common in both en-
gineering design and model parameter estimation. We describe a tool,
Nimrod/O, that expedites the solution of such problems by performing
evaluations concurrently, utilizing a range of platforms from worksta-
tions to widely distributed parallel machines. Nimrod/O offers a range
of optimization algorithms adapted to take advantage of parallel batches
of evaluations. We describe a selection of case studies where Nimrod/O
has been successfully applied, showing the parallelism achieved by this
approach.
