Introduction to modern methods for numerical solution of systems of partial differential equations obtained by mathematical modeling of continuum mechanics problems (heat transfer, fluid flow, elastic deformation, etc.). The course includes overview of the basic software for numerical computation and its application to solution of PDEs. Major part includes overview and practical use of parallel HPC computational cluster, the basic numerical libraries (Blas, Lapack, Petsc, etc. ), finite element libraries (Fenics) and libraries for parallel computation (MPI, OpenMP)
