ncnn/benchmark

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

# 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

# copy all param files to the current directory
$ ./benchncnn [loop count] [num threads] [powersave] [gpu device]

run benchncnn on android device

# 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]

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

Typical output (executed in android adb shell)

Qualcomm MSM6150 Snapdragon 675 (Kyro460 2.0GHz x 2 + Kyro460 1.7GHz x 6 + Adreno 612)
