Optimization R&D focuses on the development of algorithms for simulation-based objective functions. Specific areas of research include parallel optimization, model management, and interior-point methods.

Fault-tolerant algorithms are essential for the robustness of large-scale distributed simulations. Research includes the development of fault detection and recovery techniques for large cluster systems assembled from commodity parts.
