BakaBench

What is this?

This program is a benchmark program that is the simplest, most straightforward, and “Baka” (the most foolish). This program measures performance by continuously adding 1 for a certain period of time (default is 10 seconds) and evaluating the resulting value.

What is “Baka”?

“Baka” (バカ) means “foolish” in Japanese and is commonly used with a connotation of insult or self‑deprecation. This benchmark program is very simple and does nothing complicated; it just continuously adds 1, which is why it is considered quite foolish. Therefore, this program is named “Baka.”

How to build

The recommended compiler is g++. It is likely that it can also be compiled with clang++, but g++ is preferred for the sake of uniformity in benchmark conditions. This program does not use any build systems like make. It can be easily built with the following command.

g++ -O0 bakabench.cxx -o bakabench

How to use

Usage example:
bakabench -d 10

Options:
-a             Do not run the single‑core mode A benchmark.
-b             Do not run the single‑core mode B benchmark.
-m             Do not run the multicore benchmark.
-d <SECONDS>   Specify benchmark duration in seconds. (default: 10)
-t <THREADS>   Specify number of threads. (default: actual number of CPU threads.)
-s <MODE>      Stress test mode. Specifying 0 for MODE runs in single‑core mode; 1 runs multicore mode.
-h, --help     Print this help.
-v, --version  Print version information
