Interactive Rendering of Large Unstructured Grids Using Dynamic Level-of-Detail
We describe a new dynamic level-of-detail (LOD) technique that allows real-time rendering of large tetrahedral meshes. Unlike approaches that require hierarchies of tetrahedra, ou...

A Comparative Study of the NAS MG Benchmark across Parallel Languages and Architectures
Hierarchical algorithms such as multigrid applications form an important cornerstone for scientific computing. In this study, we take a first step toward evaluating parallel lan...

Towards a Scalable Metacomputing Storage Service
We describe a prototypical storage service through which we are addressing some of the open storage issues in wide-area distributed high-performance computing. We discuss some of t...

Adaptive deformations with fast tight bounds
Simulation of deformations and collision detection are two highly intertwined problems that are often treated separately. This is especially true in existing elegant adaptive simu...

On segmentation evaluation metrics and region counts
Five image segmentation algorithms are evaluated: mean shift, normalised cuts, efficient graph-based segmentation, hierarchical watershed, and waterfall. The evaluation is done us...
