## dynamic library
Dynamic libraries are libraries are pre compiled and often provided by the operating system, as opposed to compiling it as part of your project. This saves space as each program dont need its own "copy".
## command-line arguments
Command-line arguments are extra commands that we enter after the program's executable name so that the functionality of the program changes.

# 34. Parallelization
The following code was used for parallelization using openMP. We haven't had time to test and we have only parallelized half of what is possible. But we can see that it is using all the cores.
````
#pragma omp parallel
{
std::vector<CellMap> vec_private;
#pragma omp for
for (int i = 1; i <= num_contours; i++)
{
vec_private.push_back(produce_cellmap(heightmap, heightmap->min + interval*i));
std::cout << "Execute thread " << omp_get_num_threads() << " ";
}
#pragma omp critical
vector_contours.insert(vector_contours.end(), vec_private.begin(), vec_private.end());
}
