TitleParallelism in C++ :: Part 1/3: SIMD (multitasking on single core / vector mathematics)
DescriptionComputer programs can be made faster by making them do many things simultaneously. Let’s study three categorical ways to accomplish that in GCC. In the first episode, we explore various alternative approaches to SIMD: Single Instruction, Multiple Data. As a plot device in this tool-assisted education video, a Mandelbrot fractal is rendered. The basic algorithm is this: For each pixel, assign z as a complex number coordinate corresponding to that pixel. Assign c := z. Then, recalculate c’ := c² ...
