Gareth Lloyd (He/him)I'm putting a talk together about <a href="https://fosstodon.org/tags/programming" class="mention hashtag" rel="nofollow noopener" target="_blank">#programming</a> Mandelbrot image generator with insight into profiling and optimisation. Main part will be normal optimisations, <a href="https://fosstodon.org/tags/simd" class="mention hashtag" rel="nofollow noopener" target="_blank">#simd</a>, <a href="https://fosstodon.org/tags/multithreading" class="mention hashtag" rel="nofollow noopener" target="_blank">#multithreading</a>, and possibly gpu acceleration. I'll also show micro benchmarking, hotspot/perf, intel advisor, and also inspecting assembly code.Any other interesting bits I should look into putting into my talk?<a href="https://fosstodon.org/tags/cpp" class="mention hashtag" rel="nofollow noopener" target="_blank">#cpp</a> <a href="https://fosstodon.org/tags/cplusplus" class="mention hashtag" rel="nofollow noopener" target="_blank">#cplusplus</a>
