Denis Yaroshevskiy - "My First SIMD" - C++ London

Recorded live at the C++ London meetup at Macquarie, October 2022
www.meetup.com/cpplondon/even...
`std::strlen` is 16 or 32 times faster than a while loop, depending on your machine.
How? It uses SIMD. And so can you. The talk will show you a few algorithms with SIMD,
enough for you to get a feel for it.
The talk will utilize `eve` library github.com/jfalcou/eve but you don't have to,
the principles and ideas stay the same regardless of how you write SIMD.

Hi!
If you find the sound quality difficult on the ear - here is the previous iteration of this talk: czcams.com/video/d6NcnyXjc3I/video.html
I don't think I can post a link to the slides without CZcams blocking me but you can find them on my github in presenations repo

Thanks Denis.
I've added a link to your slides in the description.
I think we fixed your mic a bit too close, so it does distort a bit. Still understandable, though.
