Classes are essentially hands-on practice sessions of parallel computing.
Teaching involves slide presentations of theoretical material, programming examples, and programming exercises . Internet access is used for obtaining relevant material. The programming exercises are made using a command line terminal in Windows/Linux/MacOS, GNU compilers and the mpich implementation of MPI. Access to a remote computer cluster is given for the problem assignments for evaluation. Resources used
