Performance matters: new tricks for old dogs

Join session

Matt Bentley

On Day 3 at 9:00 (CET/Berlin) in Track D online

An overview of several new techniques, most of which are old ideas but with unique spins on them.

All techniques involved are performance-oriented, ie. do not attend this talk if you expect elegance, complexity and language-oriented talk. Some of the topics:

* methods for faster erasure from vectors/deques/static_vectors where order is unimportant

* cache-friendlier linked lists

* creating random-access containers with O(1) [] operators out of multiple memory blocks, but with a growth factor

Hopefully there should be something for both newcomers to the language and for 'old dogs' who can learn a few new tricks.
