SGRT: A Mobile GPU Architecture for Real-Time Ray Tracing
Recently, with the increasing demand for photorealistic graphics and the rapid advances in desktop CPUs/GPUs, real-time ray tracing has attracted considerable attention. Unfortunately, ray tracing in the current mobile ...
Megakernels Considered Harmful: Wavefront Path Tracing on GPUs
When programming for GPUs, simply porting a large CPU program into an equally large GPU kernel is generally not a good approach. Due to SIMT execution model on GPUs, divergence in control flow carries substantial performance ...
