If you haven't yet, have a look at my previous post for motivation on why vectorizing code is useful. In my … Continue reading Building a C++ SIMD abstraction (2/N) – Status Quo (My Perspective)

Howdy everyone out there! After a bit of a hiatus from writing, CppCast recently had Jonathan Boccara on as a guest to talk about blogging which has inspired me to get back to expository writing again. Recent developments in OSPRay since the summer have marked several deep changes and additions of our infrastructure, including some rewrites … Continue reading Building a C++ SIMD abstraction (1/N) – Motivation

If you have not read that post yet, I encourage you to do so and watch the associated talk which helped inspire it from Sean Parent ("no synchronization primitives"). In this post, … Continue reading Thread Parallelism (Part 2): A Simple Parallel-For Wrapper
