On Hash Functions for the GPU
This blog posts shows how the PCG2D hash function works geometrically. Further, we discuss a quantitative statistical test that may help to optimize parameters as compared to classical pass/fail test suites.

Random walk method for quaternions
The random walk method on the space of unit quaternions produces uniformly distributed quaternions without trigonometric functions. We study some performance and quality properties. CPU benchmarks show favorable results compared to the classical algorithm. Using shared memory, speedups can also be found on the GPU. Implementations in SIMD and GLSL are provided. (Note: This post…
