Note that you need need a CxxExplorer running to execute the notebooks. However, you still can open the notebooks and experience the C++Explorer features.
At the begining of the course, the students learn to use the C++ standard template library and use the Markdown cells of the Jyputer notebooks to document the code. For larger projects, the intructor uses the Markdown cells to comment and the code and gives intrusctions to the students which parts of the tempalte they should edit to accomplish the exercise. Please find a example for how to compute the median here and the template for the N-Body simualtion here.
After the inroduction of HPX in the lecture, the students learn that the need to use
run_hpx([](){
//My code
});within a Cling cell to execute the HPX code and use the parallel version of the C++ STL algorithms. Please find the example here.
After we have introduced the concept of futures and asyncronous function calls in C++, the students learn how to replace theC++ version with the HPX version. Please find one example here. Note that cling does not support thread local yet and therefore std::async will not run in the notebooks.
In the lecture, we use the pybind feature to plot the computation in C++ using the Python package matplotlib. We show this feature to the students later in the lectures as some showcase but do not use it explicit in the exercises, since the majority of them is learning C++ for the first time. Please find some example here.
For the example with std::async we have to use the terminal, since cling does not support trhead local which is internaly used by std::async. The parallel algorithms are some experimental feature of GCC and not yet available by clang/clang so we use the terminal and the g++ compiler for this feature.
