Copy libdwt-bench.c to the libdwt folder.

cd to the libdwt folder

make the library if not yet made

# make ARCH=x86_64 BUILD=release -C src libdwt.a

And compile libdwt-bench

# gcc -O3 -fopenmp -I src -L src -o libdwt-bench libdwt-bench.c -ldwt -lm

And run the driver

# ./libdwt-bench -w 3480 -h 2160

remember to set the number of threads using

# OMP_NUM_THREADS=1 ./libdwt-bench -w 3840 -h 2160

As expected, the ilv->i is not parallel! Use the ilv->d if you want parallel but then we also have to compare it with our ilv->d paraline, which does 4 memory ops.

Use the -x to switch between the ilv->i and ilv->d

# ./libdwt-bench -x -w 3480 -h 2160
