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 need to understand (and remember), but sometimes also what I’d like others to known. The style is heavily code- and experimentation based.

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

• Sorting: Micro-benchmarking a sorting algorithm.

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

• Memory Mapped Vector: Zero-copy variation of a resizable vector.

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