Outside of the course or if you prefer to use your own laptop or system to do the hands-on labs during the course, you'll need either Python + numpy + mpi4py or a C, C++, or Fortran compiler and an up-to-date MPI library, e.g., open-mpi or mpich, as well as a proper Jupyter environment if you want to run the Jupyter Notebooks locally.

The VSC exercise material (Jupyter Notebooks based on the HLRS course) is available from the:

VSC MPI GIT REPO git clone https://gitlab.tuwien.ac.at/vsc-public/training/MPI

The HLRS exercise material can be downloaded from: (To verify your MPI library/installation please download either TEST.tar.gz or TEST.zip and do the tests described in the upper part at "A) Testing MPI" in the file TEST/README.txt within the archive.)

MPI31single.tar.gz or MPI31single.zip
