A PGAS-based Implementation for the Unstructured CFD Solver TAU Open
Whereas most applications in the realm of the partitioned
\nglobal address space make use of PGAS languages we here
\ndemonstrate an implementation on top of a PGAS-API. In
\norder to improve the scalability of the unstructured CFD

Accelerated single ray tracing for wide vector units Open
Utilizing the vector units of current processors for ray tracing single rays through Bounding Volume Hierarchies has been accomplished by increasing the branching factor of the acceleration structure to match the vector width. A high branc…

Parallel Spatial Splits in Bounding Volume Hierarchies Open
Bounding volume hierarchies (BVH) are essential for efficient ray tracing. In time-constrained situations such as real-time or large model visualization, fast construction of BVHs usually compromises hierarchy quality, resulting in reduced…
