EXAMPLES AND EXERCISES FOR PACS COURSE

This repo contains source code and descriptions for the examples and exercises that will be explained during the APSC (Advanced Programming for Scientific Computing) course at Politecnico di Milano, also known as PACS (Programmazioen Avanzata per il Calcolo Scientifico)

The repository contains submodules, so to check it out properly you have to type

git clone --recursive https://github.com/pacs-course/pacs-examples.git

or (preferred choice!)

git clone --recursive git@github.com:pacs-course/pacs-examples.git

In the latter case you have to register your ssh keys on a github account.

To keep your local repo update with changes upstream do frequently

git pull --recurse-submodules

or just, from this directory,

./update.sh

The software requires a c++ compiler, i.e. gcc >= 8.0 or clang >= 8, and the Eigen library for linear algebra version 8.

You may check the version of you compiler with the option -v. Several examples have now been ported to c++17 and some examples to c++20. Check wether your compile support those standards. You may have a look on https://en.cppreference.com/w/cpp/compiler_support

This directory contains some utilities:

** load_modules If you use the module system, typing

source load_modules

or

. load_modules.sh

will load the main modules used in the examples, a part hdf5 which is used only on the example on input-output streams.

Installing git submodules

If you do not have used --recursive when cloning this repo and you want to use the git submodules containing third party software type:

./install_git_submodules.sh

The file submodule_commands.txt contains some reminder of useful git commands for operating with submodules. We also have the following utilities

• change_submodules_url.sh changes the protocol of the submodules to https. You should not need it!

• change_submodules_url_ssh.sh changes the protocol of the submodules to ssh. You should not need it!

WHAT DO DO NEXT?

• Go to the Extras/ directory that contains additional software used by some examples and follow the instructions in the local README.md file.
• Go to the Examples/ directory and follow the instructions in the local README.md file.
