BIT_Bcast#

BIT_Bcast is a page written by a scientific software developer and discusses topics from software engineering from the point of view of scientific and high-performance computing.

The selection of topics is driven by what I needed to understand (and remember) at some point. The style is heavily code- and experimentation based and probably often too terse.

Currently ,it consists of, for lack of a better word, Short Stories. They’re mildly entertaining observations about technical details that usually have some performance related twist to them:

  • Sorting: Micro-benchmarking a sorting algorithm.

  • Copying Fast: Simple question: how to copy bytes fast? (Unsatisfying answer.)

  • mdspan: The implementation of <mdspan> I contributed to libstdc++ offered a few nice opportunities to look at disassembly.
