"Parallel Path Tracing using Incoherent Path-Atom Binning" by David Coulthurst, et al., discusses a new
approach to the classic ray-tracing problem of memory access latency:
An unbiased path tracing algorithm is presented that is insensitive to the coherency of the rays
traced, allowing it to run on diverse architectures including massively SIMD processors. Instead of
grouping together packets of coherent rays, with all the limitations this implies, the problem was
reworked to set aside the recursive calculation portion from the main computation and implemented
on the massively parallel SIMD architecture, the ClearSpeed CSX600.
This paper was recently presented at the 2008 Spring Conference On Computer Graphics (http://www.sccg.sk/pages/programme/programme2008.htm)
