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 ...

The reconfiguration enables the core to operate as a SIMD processor (with N processing elements), as a MIMD/multiprocessor processor (with N/4 processing elements), or as a mixed-mode processor ...

The interleaving of MIMD and SIMD modes is performed at the granularity of single microprogrammed operation. To amortize the cost of MIMD execution, we propose a decoupling of data access from data ...
