> The Parallelism TS, a.k.a. “Parallel STL.” This includes parallelized versions of most STL algorithms
I hadn't seen this before now, this is super exciting!
Isn't this exactly the kind of thing that should be done by the compiler?
Not really. The payoff is low unless it's done in exactly the right place. If I've already partitioned the work into threads the last thing I want is the compiler taking it upon itself to parallise loops that execute in those threads.
The compiler may do vectorization, but not splitting up things into multiple threads.
"The default is to continue on the 3-year cycle (aim for C++20 then C++23), but we’re also thinking about whether to try out going to a 2-year cycle (aim for C++19, and if that works then C++21 and C++23)."
