An Energy and Bandwidth Efficient Ray Tracing Architecture
(ACM, 2013)
We propose two hardware mechanisms to decrease energy consumption on massively parallel graphics processors for ray tracing while keeping performance high. First, we use a streaming data model and configure part of the L2 ...
SGRT: A Mobile GPU Architecture for Real-Time Ray Tracing
(ACM, 2013)
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
(ACM, 2013)
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 ...
