Abstract
Quadratic programs (QPs) are central to many graphics applications, especially large-scale physically based animation, where they lead to sparse problems with hundreds of thousands to millions of degrees of freedom. Yet, benchmark datasets for such large and sparse QPs are vastly missing. We address this by extending the SimJEB dataset with explicit contact handling and by releasing a new collection of QPs derived from these scenarios. Our setup replaces the abstract contact force in the original GE Jet Engine Bracket Challenge with an explicit cylinder mesh pin, yielding realistic large-scale sparse QPs with up to nearly two million degrees of freedom. We describe the dataset construction and characteristics, and provide it to support fair and reproducible evaluation of QP solvers in graphics and related fields.
