Ray tracing efficiently models complex illumination effects to improve visual realism in computer graphics. Typical modern GPUs use wide SIMD processing, and have achieved impressive performance for a ...

SIMD architectures are less efficient for applications with the diverse control-flow behavior, which can be mainly attributed to the requirement of the identical control-flow. In this paper, we ...

In today’s automobiles, manufacturers competitively blend performance and custom features with cutting-edge safety technology. In today’s automobiles, manufacturers competitively blend ...

The MIMD (Multiple Instruction, Multiple Data) execution model is more flexible than SIMD (Single Instruction, Multiple Data), but SIMD hardware is more scalable. GPU (Graphics Processing Unit) ...

However, SIMD efficiency can be reduced due to the divergent branching and memory access patterns that are common in ray tracing codes. This paper explores an alternative approach using MIMD ...
