The research team of IT4Innovations National Supercomputing Center is focused on the development of highly scalable algorithms for the solution of linear and nonlinear problems arising from different engineering applications. In this paper, our main parallelization technique including the variants TFETI and HTFETI are described. In addition, our efficient quadratic programming algorithms implemented into our in-house software packages, are shown to demonstrate high scalability up to tens of thousands of cores.
