benchncnn can be used to test neural network inference performance Only the network definition files (ncnn param) are required. The large model binary files (ncnn bin) are not loaded but generated randomly for speed test. More model networks may be added later. --- Build ```shell # assume you have already build ncnn library successfully # uncomment the following line in <ncnn-root-dir>/CMakeLists.txt with your favorite editor # add_subdirectory(benchmark) cd <ncnn-root-dir>/<your-build-dir> make -j4 # you can find benchncnn binary in <ncnn-root-dir>/<your-build-dir>/benchmark ``` Usage ```shell # copy all param files to the current directory ./benchncnn [loop count] [num threads] [powersave] [gpu device] [cooling down] ``` run benchncnn on android device ```shell # for running on android device, upload to /data/local/tmp/ folder adb push benchncnn /data/local/tmp/ adb push <ncnn-root-dir>/benchmark/*.param /data/local/tmp/ adb shell # executed in android adb shell cd /data/local/tmp/ ./benchncnn [loop count] [num threads] [powersave] [gpu device] [cooling down] ``` Parameter |param|options|default| |---|---|---| |loop count|1~N|4| |num threads|1~N|max_cpu_count| |powersave|0=all cores, 1=little cores only, 2=big cores only|0| |gpu device|-1=cpu-only, 0=gpu0, 1=gpu1 ...|-1| |cooling down|0=disable, 1=enable|1| Tips: Disable android UI server and set CPU and GPU to max frequency ```shell # stopping android ui server, can be retarted later via adb shell start adb root adb shell stop # executed in android adb shell # set cpu performance mode echo "performance" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor echo "performance" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor echo "performance" > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor echo "performance" > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor echo "performance" > /sys/devices/system/cpu/cpu4/cpufreq/scaling_governor echo "performance" > /sys/devices/system/cpu/cpu5/cpufreq/scaling_governor # set gpu performance mode (eg.
