About

Hi, I am Reiner.

I hold a M.Sc. degree in Computer Science from the Karlsruhe Institute of Technology (KIT) with a specialization in compiler construction and computer graphics. I am a doctoral researcher in the computer graphics group of Carsten Dachsbacher with a focus on real-time visualization. My core professional interests lie in optimizing compilers and manual optimization for GPUs—especially when targeting cross-platform deployment. More specifically, I am interested in:

A Fast GPU Schedule For À-Trous Wavelet-Based Denoisers

Reiner Dolp, Johannes Hanika, and Carsten Dachsbacher
Proceedings of the ACM on Computer Graphics and Interactive Techniques, Volume 7, Issue 1, I3D, 2024

We introduce a technique to apply a series of increasingly dilated filters or convolutions quickly. This technique implements a recursive permutation of GPU thread indices. Intuitively, this permutation sorts and groups threads by their accessed memory addresses to increase memory throughput.
