Simple VGG16 from Scratch

This is a simple implementation of the VGG16 net from scratch written in C++.

Build & Run

$ make clean; make; ./vgg16
$ make clean; make BENCHMARK=1; ./vgg16

Unit Test

$ make clean; make test; ./vgg16_test

Output

$ make clean; make BENCHMARK=1; ./vgg16
rm -rf objs *~ vgg16 vgg16_test
mkdir -p objs/
clang++ main.cpp -Iobjs/ -O3 -std=c++17 -Wall -fopenmp  -DBENCHMARK -c -o objs/main.o
clang++ -Iobjs/ -O3 -std=c++17 -Wall -fopenmp  -DBENCHMARK -o vgg16 objs/main.o
