tinymembench

This is a simple memory benchmark program, which tries to measure the peak bandwidth of sequential memory accesses and the latency of random memory accesses. Bandwidth is measured by running different assembly code for the aligned memory blocks and attempting different prefetch strategies.

Benchmark

The benchmark results for some hardware can be found in the wiki page: https://github.com/ssvb/tinymembench/wiki

Build from source

This program can be compiled in either linux or windows (via mingw32 and msys) by simply running make:

$ make

Adding extra optimization options is possible:

$ CFLAGS="-O2 -march=atom -mtune=atom" make

Example of crosscompiling for Arm:

$ CC=arm-linux-gnueabihf-gcc CFLAGS="-O2 -mcpu=cortex-a9" make

Example of crosscompiling and running the benchmark on Android device:

$ CC=arm-linux-gnueabihf-gcc CFLAGS="-O2 -mcpu=cortex-a8 -static" make
$ adb push tinymembench /data/local/tmp/tinymembench
$ adb shell /data/local/tmp/tinymembench
