• Challenge repository: https://github.com/gunnarmorling/1brc

The challenge: compute simple floating-point math over 1 billion rows. As fast as possible, without dependencies.

Implemented in C++ 20, with GCC 10 (that's why there is a copy of fast_float.h)

Running the challenge

Tested on Debian Linux 11 with GCC 10:
